12 Quick Safe Ways to Speed Up Windows 11 Without New Hardware

If your Windows 11 PC feels sluggish, a focused cleanup and a handful of practical tweaks will usually deliver the biggest performance gains without buying new hardware—this guide walks through 12 easy, high-impact changes to speed up Windows 11, explains why they work, and flags the risks to avoid so you don’t trade stability for a tiny boost.

Background / Overview​

Windows installs, updates, and everyday use create a steady accumulation of temporary files, old update leftovers, unused apps, and background services that quietly steal CPU cycles, memory and disk space. The result is slower boot times, choppy multitasking, and stalled updates. The good news: many of those problems are fixable with built‑in tools and a few safe manual steps.
This article combines a practical cleanup checklist with verified technical guidance for the most common root causes of a slow Windows 11 machine. Where appropriate, system commands and OS settings are shown; each technical claim has been cross‑checked with Microsoft documentation and independent tooling references to ensure accuracy.

Why cleaning matters: the real bottlenecks​

A few factors repeatedly show up in real‑world troubleshooting:

• Low free space on the OS (C drive reduces available pagefile and caching space and makes updates and background maintenance fail more often.
• A crowded startup list and background services lengthen boot time and reduce available RAM.
• Visual effects, indexing, and background syncing increase CPU cycles and I/O.
• Fragmented or slow storage (HDD vs SSD) dramatically affects perceived responsiveness.

Fixing these high‑value targets yields a much better return than sweeping registry cleanups or one‑click “boosters.” Modern Windows rarely benefits from registry cleaners, and those tools can break applications—avoid them.

---

1. Run Windows’ built‑in disk cleanup and Storage Sense (safe first step)​

Windows offers two solid, supported ways to remove temporary files and old update payloads: the classic Disk Cleanup and the newer Cleanup recommendations / Storage Sense in Settings. Use the Settings > System > Storage > Cleanup recommendations to get a user‑friendly review of temporary files, large or unused files, and previous Windows installations. Storage Sense can be configured to run automatically and to clear the Recycle Bin and old Downloads items. Microsoft documents Storage Sense and Cleanup recommendations as the supported, safe mechanism for freeing space.

• How to use it:
• Open Settings > System > Storage > Cleanup recommendations.
• Review categories (Temporary files, Large or unused files, Previous Windows installation(s)) and click Clean up for the items you want to remove.
• If you prefer automation, enable Storage Sense and configure its cadence (daily, weekly, monthly) and how it handles Downloads and Recycle Bin items.

Why this matters: freeing even a few gigabytes on a nearly full system drive restores space for virtual memory, update staging and caching—often the single fastest fix for a sluggish PC.

---

2. Analyze and clean the Windows Component Store (WinSxS) safely with DISM​

Windows keeps a component store (WinSxS) that grows after updates. You can analyze its reclaimable space, then run DISM’s StartComponentCleanup to remove superseded components. Use an elevated command prompt for these commands:

• Analyze: dism.exe /online /cleanup-image /AnalyzeComponentStore
• Cleanup: dism.exe /online /cleanup-image /StartComponentCleanup

Running Analyze first is optional but useful to see recommended reclaimable space. Microsoft’s guidance and multiple Windows experts confirm these commands as the supported way to manage the component store; run them only from an elevated prompt and allow the operation to complete. In many cases manual cleanup via DISM frees several gigabytes.
Caution: avoid manual deletion inside the WinSxS folder—this can render Windows unbootable. Use DISM, Disk Cleanup, or the scheduled “StartComponentCleanup” task instead. Some administrators use the /ResetBase switch (StartComponentCleanup /ResetBase) to remove older component versions permanently—only do that on stable systems because it prevents uninstalling updates.

---

3. Empty or curate the Downloads folder (fast wins)​

Most users forget the Downloads folder. Sorting by size and deleting installers, ISO images, old installers, and videos can free tens of gigabytes instantly.

• Open File Explorer > Downloads, sort by Size, and remove what you don't need.
• If you need to keep files, move them to an external drive or to cloud storage with OneDrive Files On‑Demand enabled to keep placeholders locally small.

This is straightforward housekeeping, but because it’s manual it’s easy to miss—schedule an occasional sweep.

---

4. Use a disk space visualizer to find hidden hogs (WizTree recommended with caveats)​

A disk visualizer shows files and folders sorted by size and a treemap view so you can find unexpectedly large files quickly. WizTree is a highly regarded lightweight tool that scans fast and displays results both as lists sorted by size and as a treemap chart. Official downloads and package managers like Chocolatey/PortableApps carry trusted builds; be careful to use the official site or a reputable package manager because copycat sites have appeared.
Why WizTree:

• Extremely fast NTFS scanning using the Master File Table (MFT) for almost instant results.
• Clear “largest files” views and treemap visuals that speed up cleanup decisions.

Caution:

• Avoid deleting files from Windows and Program Files folders unless you understand what they are.
• Download WizTree from the official vendor page or reputable repositories to avoid malicious imitations.

---

5. Trim startup programs and background apps​

Many apps authorize themselves to run at startup and never get used. Reducing startup load shortens boot time and frees RAM.

• Open Task Manager (Ctrl+Shift+Esc) > Startup tab.
• Sort by Startup impact and disable nonessential apps (cloud storage syncers, updaters, messaging apps you rarely use).
• Keep antivirus and essential drivers enabled.

Tip: On laptops, if you want battery life and quieter operation, keep only the essential services enabled and run heavier apps manually.
Why this matters: fewer background processes means more memory and CPU available for active apps.

---

6. Check for malware and unwanted resource hogs​

Malware and PUPs (potentially unwanted programs) can consume CPU and I/O. Run a full scan with Windows Security (Microsoft Defender) and, where appropriate, a second opinion scanner such as Malwarebytes to catch things Defender misses. Multiple independent sources and security advisories recommend layered scanning when performance problems are unexplained. Regular scans are free insurance.

---

7. Adjust visual effects and experience settings​

Windows 11’s transparency, animations, and shadow effects are polished but cost CPU/GPU cycles and may add latency on older hardware.

• Search “Adjust the appearance and performance of Windows” and choose “Adjust for best performance” or customize which effects to keep.
• Disable Transparency Effects in Settings > Personalization > Colors if you want a balance between visuals and speed.

This is a low‑risk tweak that can make UI interactions feel snappier on low‑end systems.

---

8. Use the right power profile​

Set the Power mode to Best performance for desktops and when plugged in on laptops:

• Settings > System > Power & battery > Power mode, then choose Best performance (or Ultimate Performance if available on desktops).

Be aware this increases energy use and can raise component temperatures; monitor thermals on laptops and older systems.

---

9. Keep drivers and Windows updated—selectively​

Drivers (graphics, storage and network) are often the cause of poor responsiveness. Use Windows Update and the hardware vendor’s driver pages for the latest stable drivers.

• Settings > Windows Update > Advanced options > Optional updates lists driver updates.
• For GPUs, download from NVIDIA, AMD, or Intel direct for gamers and creators.

Caveat: avoid installing beta drivers unless you need a specific fix. For business or mission‑critical machines, prefer vendor‑tested driver packages.

---

10. Tune Storage: SSD over HDD, TRIM, and defragmentation​

If your PC still uses an HDD, moving Windows and your most used applications to an SSD is the single largest hardware upgrade for responsiveness. On SSDs, ensure TRIM is enabled; Windows 11 handles TRIM automatically for NVMe and SATA SSDs.
For HDDs, run Optimize Drives (defrag) occasionally. For SSDs, use built‑in optimization (retrim/maintenance) which Windows schedules automatically. The storage upgrade argument is repeated across hardware guides because of the large, measurable improvement in boot and app load times.

---

11. Manage virtual memory (pagefile) sensibly — usually leave to Windows​

Windows manages virtual memory well on modern systems. For low‑RAM systems (4–8 GB) increasing pagefile size can help, but on most systems the recommended approach is:

• Let Windows manage the paging file automatically unless you have a specific reason to set a custom size.
• If you set a manual pagefile, ensure you leave enough free space on the system drive.

Changing the pagefile can help in constrained RAM situations, but it is usually a last resort compared to adding physical RAM.

---

12. When to reset or clean‑install Windows (the nuclear option)​

If performance remains poor after the above steps, consider “Reset this PC” (Settings > System > Recovery > Reset this PC) or a clean install. Back up your data first.

• Reset with “Keep my files” preserves documents but reinstalls Windows and removes apps—this often removes hidden cruft and misbehaving services.
• Full clean install is the most reliable way to return to a known good baseline, but requires driver and app reinstall.

These steps are effective but require time for reconfiguration; use them only after trying the lighter measures above.

---

A critical look at third‑party “cleaners” and registry tweaks​

• Registry cleaners promise large gains but usually provide near‑zero measurable benefit on modern Windows and carry a real risk of breaking installed applications or system components. Experts strongly advise against routine use.
• “One‑click” optimization suites often bundle adware or attempt aggressive changes; prefer official Microsoft tools (Storage Sense, Disk Cleanup) and targeted utilities like WizTree for file discovery.
• If you use PowerShell or scripts to debloat Windows (e.g., community debloat scripts), review each action carefully and create a system restore point first.

---

Quick 10‑minute checklist (do this now)​

• Open Settings > System > Storage > Cleanup recommendations — run the suggested cleanups.
• Empty Downloads or move big files out.
• Run an elevated PowerShell or Command Prompt and execute: dism.exe /online /cleanup-image /AnalyzeComponentStore and, if recommended, dism.exe /online /cleanup-image /StartComponentCleanup.
• Open Task Manager > Startup and disable nonessential entries.
• Run Windows Security full scan (or a second‑opinion scan with Malwarebytes).

---

Expected outcomes and realistic gains​

• Freeing up several GB of system drive space typically results in a noticeably snappier system, more reliable updates, and reduced paging activity.
• Moving Windows from HDD to SSD commonly reduces boot and app load times by multiple seconds to tens of seconds—often the most visible single improvement.
• Trimming startup programs and disabling resource‑heavy visual effects produce immediate snappiness in UI responsiveness.

Be skeptical of claims promising 200% faster speeds from a single tweak—real gains are incremental and compound. Also, the amount of improvement depends on your baseline hardware, disk fullness, and what is causing the slowdown to begin with.

---

Troubleshooting common pitfalls​

• DISM /StartComponentCleanup stalls at 20%: sometimes the operation briefly pauses or completes with a short progress bar; check DISM logs at C:\Windows\Logs\DISM\dism.log and rerun /AnalyzeComponentStore to validate results. Microsoft community guidance and field reports explain that behavior can vary by build and background activity; when in doubt, reboot and run DISM again.
• If an application breaks after debloating or removing apps, restore from an earlier point or reinstall the affected software.
• If Windows Update fails after aggressive cleanup, use Windows Update Troubleshooter and the DISM /RestoreHealth sequence before attempting more invasive fixes.

---

Final verdict — balance safety and speed​

The fastest, safest route to a noticeably faster Windows 11 machine is to:

• reclaim disk space using Windows’ Cleanup recommendations and Storage Sense;
• use DISM to safely shrink the component store when recommended;
• remove large unused files (Downloads) and use a trusted disk visualizer like WizTree to locate space hogs; and
• trim startup programs while keeping essential security software enabled.

Avoid registry cleaners and one‑click booster suites. When you follow the prioritized, supported steps above you’ll usually regain the most important performance without risking stability. The PCWorld checklist the original guide promoted lines up with this approach: built‑in tools first, then targeted third‑party utilities when needed.

---

If you want, the next step is a printable quick reference with the exact commands and a short pre‑check list (create a restore point, backup large files) so you can run through this workflow on any Windows 11 PC in under 30 minutes.

[ChatGPT]

October 14, 2025 did not merely mark the end of Windows 10’s free support — it was the day Microsoft quietly exited support for a host of other high-impact, perpetual‑license products too, leaving administrators juggling migrations, emergency extended‑security programs, and a sudden spike in compliance and attack‑surface risk.

Background​

Microsoft’s lifecycle calendar has long been predictable: fixed end‑of‑support dates, followed by staged migrations toward newer products and subscription models. This October wave, however, is unusual in scope. The widely publicized end of Windows 10 support was the headline, but the same day also finished mainstream and extended pipelines for older Office perpetual releases, multiple Exchange and Skype for Business server releases, and even certain servicing channels of Windows 11. That aggregation of product sunsets turned October 14 into one of the busiest — and riskiest — single days on many enterprise IT calendars.
This feature unpacks what changed, what remains available as a lifeline, and the operational and security trade‑offs organizations must weigh right now. It cross‑verifies Microsoft’s lifecycle announcements and program briefs, highlights crucial discrepancies administrators should watch for, and offers a prioritized migration checklist for enterprises and small organizations alike.

---

What reached end of support on October 14, 2025​

The headline: Windows 10​

• Windows 10 (all supported editions) reached end of support on October 14, 2025. After that date Microsoft stopped providing technical assistance, feature updates, and security updates for Windows 10. Devices continue to operate, but will receive no further public patches.
• Microsoft offered an Extended Security Updates (ESU) program as a one‑year bridge for consumers and a multi‑year option for commercial customers. The consumer program provides a one‑year security patch window that runs through October 13, 2026; commercial ESU options are available through Volume Licensing with a tiered renewal model.

Office perpetual editions​

• Office 2016 and Office 2019 (perpetual licenses) also reached end of support on October 14, 2025. Microsoft has formally stated there will be no ESU program for these perpetual Office versions — they will not receive security updates after this date. Organizations relying on Office 2016/2019 must migrate to Microsoft 365 (subscription) or to Office LTSC 2024 to retain supported, on‑premises, perpetual licensing.
• Office LTSC 2024 (Long Term Servicing Channel) is the perpetual‑license alternative Microsoft is offering; its fixed lifecycle runs to October 2029 for supported editions. That buys on‑premises customers a longer supported runway, but LTSC intentionally omits the continuous feature updates that Microsoft 365 subscribers receive.

Exchange and Skype for Business servers​

• Exchange Server 2016 and Exchange Server 2019 moved to end of support on October 14, 2025. Microsoft’s lifecycle pages and Exchange team communications stress that security and non‑security fixes will cease for these versions after that date.
• Skype for Business Server 2015 and 2019, along with client versions aligned to those releases, also reached end of support the same day. Microsoft’s guidance pushes migrations to Skype for Business Server Subscription Edition (SE) or to Microsoft Teams.

---

The lifeline: Extended Security Updates (ESU) programs and limits​

Windows 10 ESU: consumer and commercial differences​

Microsoft set up two separate ESU paths for Windows 10:

• Consumer ESU: a one‑year program ending October 13, 2026, with three enrollment options — free enrollment via cloud backup/synced Microsoft account, redemption of 1,000 Microsoft Rewards points, or a one‑time $30 purchase. Enrolment requires Windows 10 version 22H2 and an administrative Microsoft account on the device. This consumer ESU covers security updates rated Critical or Important by the Microsoft Security Response Center (MSRC) and does not include support or feature updates.
• Commercial ESU: available via Volume Licensing for organizations, commercially priced per device with the possibility to renew annually for up to three years. Microsoft published a stepped pricing structure intended to discourage long‑term reliance: Year 1 list pricing is modest relative to replacement costs, but subsequent years increase and are commonly modeled to double annually, emphasizing migration rather than indefinite deferral. This ESU also only delivers security updates and not full technical support.

Important operational considerations:

• ESU is a bridge, not a port in the storm. It’s explicitly time‑boxed and limited to Critical/Important security fixes.
• Consumer ESU ties enrollment to a Microsoft account and cloud sync — a privacy and compliance trade‑off that may be unacceptable in regulated or isolated environments.
• Commercial ESU pricing can become material at scale; organizations must model ESU costs against procurement and migration expenses.

Exchange and Skype for Business ESU: a last‑minute six‑month offer​

For on‑premises messaging and UC systems, Microsoft introduced a narrow, private ESU program for Exchange Server 2016/2019 and Skype for Business Server 2015/2019:

• This program is six months long and runs through April 14, 2026. It is not an extension of lifecycle support; instead, it offers private delivery of any Critical or Important security updates that Microsoft elects to issue during that six‑month window. Microsoft does not guarantee updates will be released. Enrollment requires contacting Microsoft account teams and is priced per server.

Why this matters:

• Many organizations still operate on‑premises Exchange or Skype servers for regulatory, latency, or air‑gapped reasons. The six‑month ESU buys time — and only time — for final migration to Exchange Subscription Edition (SE) or to cloud services like Exchange Online/Teams.
• The private nature of the ESU (updates delivered privately, not via public update channels) requires planning for testing and deployment pipelines that accommodate non‑public patch delivery.

---

Why the simultaneous sunsets matter: security, compliance, and attack surface​

Office perpetual versions remain a juicy attack vector​

Even if Windows devices are upgraded, perpetual Office installs that stop receiving patches create a significant vector for compromise. Office’s deep file‑handling footprint and macro support historically attract attackers, and while Microsoft has hardened Office (for example, by disabling VBA macros by default), unsupported Office versions remain a persistent risk. The end of Office 2016/2019 without an ESU option means organizations cannot rely on Microsoft for security fixes; they must migrate or accept escalating exposure.

Compound risk: unsupported OS + unsupported apps + on‑prem servers​

When multiple components lose support simultaneously, risk compounds. Common scenarios that raise immediate alarm:

• An organization still running Windows 10 endpoints plus on‑premises Exchange 2019 and Office 2016 becomes an attractive target: any new zero‑day exploiting Office or Exchange could lack timely patches for multiple layers.
• Regulatory frameworks (PCI, HIPAA, NIST, ISO) often require supported, patched software; continuing to run unsupported stacks can jeopardize compliance and insurance coverage.
• Migration teams historically under‑resourced for a single product end‑of‑life now face concurrent projects across OS, productivity, and messaging platforms.

---

Migration options and their trade‑offs​

1) Move to Microsoft 365 (cloud‑first)​

• Benefits:
• Continuous security and feature updates.
• Consolidated identity and management (Azure AD, Intune).
• Rapid access to new capabilities (co‑authoring, cloud storage).
• Drawbacks:
• Subscription cost model and long‑term OPEX.
• Data residency, offline operation, or air‑gap constraints may hinder adoption for some regulated organizations.
• Potential vendor lock‑in and platform dependence.

2) Shift to Office LTSC 2024 and on‑premises server subscription SE​

• Benefits:
• Perpetual license option for organizations that cannot use cloud subscriptions.
• Office LTSC 2024 receives security updates through Oct 9, 2029 — a multi‑year supported runway without feature churn.
• Exchange/SFB Subscription Edition (SE) offers a modern lifecycle for on‑prem deployments.
• Drawbacks:
• LTSC intentionally excludes continuous feature updates — you trade innovation for stability.
• Server SE migrations may be complex, especially for environments with heavy custom integrations.

3) Purchase ESUs as a controlled bridge​

• Benefits:
• Buys time for orderly migration planning and execution.
• Minimizes immediate exposure when hardware or application compatibility prevents instantaneous upgrades.
• Drawbacks:
• ESU costs can escalate and are time‑limited.
• Consumer ESU enrollment conditions may be incompatible with privacy or compliance needs.
• For Exchange and Skype for Business, ESU availability was limited and private — not a scalable, long‑term solution.

4) Replace hardware / adopt alternative OS​

• Benefits:
• Upgrading to modern hardware can unlock Windows 11 benefits and improved security posture.
• Switching to supported Linux distributions or ChromeOS Flex can eliminate Microsoft dependency for certain workloads.
• Drawbacks:
• Migration complexity, retraining costs, and application compatibility remain significant barriers.

---

Practical, prioritized mitigation checklist for administrators​

Follow this ordered list to triage and reduce exposure in the next 30–180 days:

• Inventory and prioritize: Create an authoritative inventory of endpoints, servers, and Office installs. Flag devices on Windows 10, Office 2016/2019, Exchange 2016/2019, and Skype for Business servers.
• Verify versions and update levels: Ensure Windows 10 devices are on version 22H2 if you plan to enroll in consumer ESU; confirm Exchange/Skype server cumulative update baselines required for ESU eligibility.
• Decide per‑workload path:
• Move users with cloud‑ready profiles to Microsoft 365.
• Reserve LTSC for locked‑down, air‑gapped, or regulated desktops that cannot tolerate cloud.
• Plan Exchange migrations to Exchange SE or Exchange Online with prioritized mailbox moves.
• If ESU is needed, enroll now: Consumer ESU enrollment windows run through October 13, 2026; commercial ESU enrollment requires Volume Licensing and should be processed promptly to avoid gaps.
• Harden surviving endpoints: Apply network segmentation, elevate monitoring, deploy strong EDR, enforce least privilege, and isolate any unsupported instances where migration is not yet possible.
• Engage legal/compliance: Map unsupported products to regulatory controls and insurance requirements. Document compensating controls if a temporary ESU is used.
• Test rollback and patch pipelines: For private ESU patches (Exchange/Skype), ensure test environments can receive and validate non‑public updates.
• Budget and timeline: Model TCO — include ESU cost, consultant/migration services, new hardware, and cloud subscription fees. Present options to finance and senior leadership with clear timelines and risks.

---

Cost modeling and the hard numbers​

• For many organizations the math is stark: commercial ESU list pricing for Windows 10 starts at roughly $61 per device in Year 1 with steep increases projected for subsequent renewals; consumer one‑year ESU is available for $30 or via no‑cost enrollment paths that require Microsoft account and sync. The cumulative cost of multi‑year ESU at scale often rivals or exceeds hardware refresh or cloud migration costs when multiplied across tens of thousands of endpoints.
• For Exchange and Skype on‑premises, Microsoft’s ESU is priced per server and limited to six months; this should be viewed strictly as an emergency window for migration rather than a financial planning instrument.
• Office perpetual users face a different reality: no ESU was offered for Office 2016/2019, so the only supported perpetual option is Office LTSC 2024 (support through Oct 9, 2029). Migrating to LTSC involves a new procurement cycle and explicit acceptance of a static feature set.

---

Strategic implications: cloud migration, vendor strategy, and operational resilience​

Microsoft’s commercial signal: accelerate migration​

Microsoft’s lifecycle decisions — and specifically the manner in which ESU pricing escalates year‑over‑year — are a clear nudge toward migration to cloud and subscription models. The economics are designed to make migration more attractive than indefinite ESU renewal. For many organizations this simply accelerates an already‑planned cloud shift; for others it forces a strategic decision between perpetual control and ongoing operational cost.

Risk to organizations that prefer perpetual licensing​

• Organizations that prefer perpetual licensing for compliance, offline operation, or predictable CapEx are now squeezed. Office LTSC 2024 and on‑premises server subscription editions offer alternatives, but they come with operational trade‑offs and lifecycle limits that must be baked into long‑term planning.

The operational spotlight on discovery and patch management​

• The cascade of sunsets underscores the importance of robust discovery tools. Tools that can identify installed Office versions, Exchange build numbers, and Windows 10 update status should be run immediately. Failing to detect unsupported installations is now a material operational risk. Observers have warned that the Office EoS might fly under the radar of teams focused exclusively on Windows 10 — that problem is now reality.

---

Areas where claims and expectations require caution​

• Microsoft’s private ESU programs (Exchange/Skype) are explicitly not lifecycle extensions and do not guarantee patch issuance. Treat them as conditional — if Microsoft finds nothing requiring a security update, no patches will be produced during the ESU window. That caveat should be factored into migration plans and risk acceptance paperwork.
• Consumer ESU enrollment mechanisms involve Microsoft account ties and cloud sync; organizations that assume a pure offline path to secure extended patches are mistaken. The commercial ESU path remains the appropriate route for enterprise needs, but it carries cost and administrative overhead.
• Any public commentary that models global financial exposure (for example, “billions at stake”) depends heavily on variable inputs: installed base counts, negotiated discounts, cloud adoption rates, and how many systems can be upgraded in place. Those headline numbers are useful thought experiments but should not replace organization‑specific modeling.

---

Final analysis and recommendations​

The October 14 wave of end‑of‑support events is more than symbolic: it’s operationally consequential. When multiple widely deployed Microsoft products exit support on the same date, organizations face a compressed window to reduce exposure without disrupting services.
Prioritized recommendations:

• Treat the next 90 days as high urgency for discovery, enrollment (if ESU fits your short term plan), and migration sequencing.
• Use ESU only as a controlled bridge — do not rely on it as a long‑term strategy.
• If you must retain perpetual licensing, plan for Office LTSC 2024 where applicable and budget for the trade‑offs in features versus control.
• For messaging and UC: prioritize Exchange and Skype server migrations now; the six‑month private ESU window is short and conditional.
• Integrate legal, procurement, and compliance teams into migration planning. Unsupported software has downstream impacts on audits, insurance, and contractual obligations.

The net effect of October 14 is a crucible for IT organizations: those that planned, budgeted, and executed migrations will see minimal disruption; those that were narrowly focused on a single product’s retirement — Windows 10 — and postponed other migration work now confront a compressed schedule with elevated risk. The time to inventory, decide, and act was yesterday; the time to do it decisively is now.
