If your Windows 10 PC is eligible, you can still move to Windows 11 at no cost—and even machines that Microsoft labels “incompatible” often have practical, community-tested workarounds that will get you onto the newer OS today. This feature explains every supported route Microsoft provides, walks through the unofficial Rufus-based bypass used by enthusiasts, verifies the key technical requirements and dates against Microsoft’s documentation, and lays out the security and update trade‑offs so you can choose the safest path for your hardware and use case.
Microsoft set a stricter compatibility baseline for Windows 11 than for past feature upgrades. The baseline is intended to raise the security floor of the platform by requiring UEFI + Secure Boot, TPM 2.0, and a set of supported processor models, along with minimum memory and storage. Those checks are enforced in the official upgrade flows and are the reason many older but still serviceable Windows 10 PCs are flagged as “incompatible.”
At the same time, Windows 10 reached its published end-of-support date—meaning consumers who remain on Windows 10 after that date must either upgrade, enroll in Microsoft’s consumer Extended Security Updates (ESU) program for a one‑year bridge, or accept the increasing security risk of running an unsupported OS. Microsoft’s consumer ESU rollout offers several enrollment paths (including a free option via Windows Backup to OneDrive, a Microsoft Rewards redemption, or a paid one‑time purchase) and runs through October 13, 2026. These enrollment details are published by Microsoft and have been widely documented.
The practical reality today: most users with relatively recent hardware can upgrade for free through Microsoft’s supported channels; users with older hardware have three practical choices—update firmware or enable TPM/Secure Boot (if present), enroll in the consumer ESU bridge to buy time, or, if technically comfortable, use a community tool such as Rufus (or a registry bypass) to install Windows 11 on unsupported hardware. The community routes work in many cases but are explicitly unsupported by Microsoft and carry potential long‑term update, security and stability implications.
Limitations: Microsoft rolls out feature updates in stages; if you’re eligible but don’t see the offer immediately, it may be staged.
Caveat: due to a known recent regression in Microsoft’s Media Creation Tool, some Windows 10 hosts may experience the tool closing unexpectedly; Microsoft has documented this as a known issue and recommends the ISO‑download workaround while a fix is prepared. That advisory is live in Microsoft’s release‑health pages.
A typical Rufus flow looks like this:
Upgrading to Windows 11 remains free for qualifying Windows 10 PCs, and there are trusted ways to bring many older machines forward—whether by enabling firmware features, enrolling in ESU as a bridge, or using community tooling when you accept the trade‑offs. Prioritize backups, verify compatibility with PC Health Check, prefer Microsoft’s supported paths when possible, and treat unsupported workarounds as short‑term solutions that require ongoing vigilance and maintenance.

Background / Overview
Microsoft set a stricter compatibility baseline for Windows 11 than for past feature upgrades. The baseline is intended to raise the security floor of the platform by requiring UEFI + Secure Boot, TPM 2.0, and a set of supported processor models, along with minimum memory and storage. Those checks are enforced in the official upgrade flows and are the reason many older but still serviceable Windows 10 PCs are flagged as “incompatible.” At the same time, Windows 10 reached its published end-of-support date—meaning consumers who remain on Windows 10 after that date must either upgrade, enroll in Microsoft’s consumer Extended Security Updates (ESU) program for a one‑year bridge, or accept the increasing security risk of running an unsupported OS. Microsoft’s consumer ESU rollout offers several enrollment paths (including a free option via Windows Backup to OneDrive, a Microsoft Rewards redemption, or a paid one‑time purchase) and runs through October 13, 2026. These enrollment details are published by Microsoft and have been widely documented.
The practical reality today: most users with relatively recent hardware can upgrade for free through Microsoft’s supported channels; users with older hardware have three practical choices—update firmware or enable TPM/Secure Boot (if present), enroll in the consumer ESU bridge to buy time, or, if technically comfortable, use a community tool such as Rufus (or a registry bypass) to install Windows 11 on unsupported hardware. The community routes work in many cases but are explicitly unsupported by Microsoft and carry potential long‑term update, security and stability implications.
Check for Compatibility (the first and essential step)
Before doing anything else, confirm whether your machine truly needs a workaround.- Run PC Health Check (Microsoft’s official compatibility tool). It reports whether TPM is present and enabled, whether Secure Boot is on, and whether your CPU is on Microsoft’s supported list. Many “incompatible” flags are actually firmware/configuration issues you can fix by toggling settings in UEFI/BIOS.
- Verify your Windows 10 build. To upgrade smoothly you should already be on a supported Windows 10 build (Windows 10, version 2004 or later; in practice Windows 10 22H2 is the version referenced for consumer ESU eligibility). If you’re not on an up-to-date Windows 10, install updates first.
- Processor: 1 GHz or faster with 2 or more cores on a compatible 64‑bit processor or SoC.
- Memory: 4 GB RAM.
- Storage: 64 GB or larger.
- System firmware: UEFI, Secure Boot capable.
- TPM: Trusted Platform Module (TPM) version 2.0 (discrete or firmware/fTPM).
- Graphics: DirectX 12 compatible with WDDM 2.x driver.
- Display: 720p, >9" diagonal, 8‑bit color.
The Supported, Free Upgrade Routes (use these first)
If your PC passes Microsoft’s checks—or you can enable the required firmware features—the supported options are simple and preserve your entitlement to updates and Microsoft support.1) Windows Update (the simplest, safest path)
- Go to Settings → Update & Security → Windows Update → Check for updates.
- If Microsoft has offered the Windows 11 feature update to your device it will appear as “Upgrade to Windows 11 — Download and install.” This preserves apps, settings and your files in most cases and keeps you on Microsoft’s supported update channel.
Limitations: Microsoft rolls out feature updates in stages; if you’re eligible but don’t see the offer immediately, it may be staged.
2) Windows 11 Installation Assistant (official in‑place tool)
- If Windows Update hasn’t shown the offer yet but your PC is compatible, download and run Microsoft’s Windows 11 Installation Assistant. Accept the prompts and it will perform the in‑place upgrade while you continue to use the PC. Reboot when prompted to finish.
3) Media Creation Tool or ISO (create installation media)
- Create installation media via Microsoft’s Media Creation Tool or download a direct ISO from Microsoft’s Download Windows 11 page.
- Use an 8 GB (or larger) USB flash drive to create a bootable installer, or mount the ISO and run setup.exe inside Windows to do an in‑place upgrade.
- If the Media Creation Tool is unavailable on your Windows 10 host, you can download the ISO directly and either mount it or use a third‑party utility to create a bootable USB.
Caveat: due to a known recent regression in Microsoft’s Media Creation Tool, some Windows 10 hosts may experience the tool closing unexpectedly; Microsoft has documented this as a known issue and recommends the ISO‑download workaround while a fix is prepared. That advisory is live in Microsoft’s release‑health pages.
How to Upgrade with Microsoft’s Tools — Step‑by‑Step
- Backup first. Create a full disk image or at minimum copy Documents, Desktop and other personal data to an external drive or OneDrive. Verify backups.
- Run PC Health Check and fix firmware toggles (enable fTPM, PTT, or discrete TPM and enable Secure Boot) if your hardware supports them.
- If you see the Windows 11 offer in Windows Update, accept it and follow prompts. If not:
a. Try the Windows 11 Installation Assistant for an in‑place upgrade.
b. If you prefer a clean install or need media, download the Windows 11 ISO and either mount it or use the Media Creation Tool to create USB media (or use the ISO + Rufus approach if MCT fails on your host). - During setup you’ll be asked whether to keep personal files and apps — choose carefully. Reboot when prompted and follow first‑run setup.
- After the upgrade, run Windows Update and your OEM’s support site to install the latest drivers and firmware updates. Confirm activation and recreate a fresh restore point once everything is stable.
What if Your PC Is “Incompatible”? The Unofficial Options
If PC Health Check reports your CPU is not on Microsoft’s supported list, or TPM/Secure Boot are missing, you have these practical options:- Confirm whether the block is merely firmware/configuration related (enable fTPM/PTT, enable Secure Boot). Often that resolves the issue.
- If the machine is business‑critical and must remain secure, enroll in Microsoft’s consumer ESU program for a temporary one‑year bridge through October 13, 2026. Enrollment options include syncing Windows Backup to OneDrive (free), redeeming 1,000 Microsoft Rewards points, or paying a one‑time fee; the program and methods are described on Microsoft’s ESU support pages.
- If you’re technically comfortable and the machine is non‑critical, use community workarounds—either a registry bypass or Rufus—to install Windows 11. Both approaches are widely used but are explicitly unsupported by Microsoft and carry long‑term risks (see “Risks” section).
The supported registry tweak (what Microsoft has documented)
Microsoft has a documented registry override that relaxes the CPU and TPM check when running Setup.exe from inside Windows: create the DWORD AllowUpgradesWithUnsupportedTPMOrCPU = 1 under HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup and then run setup from a mounted ISO. This can allow an in‑place upgrade in some cases, but it is limited and not a guaranteed route for all incompatibility cases. Use it only if you understand the implications and have verified backups.Rufus: the widely used community solution
Rufus is a free, open‑source utility that creates customized Windows installers. In its “Extended Windows 11 Installation” mode Rufus can build USB media that removes checks for TPM 2.0, Secure Boot, and the 4 GB+ RAM requirement, and can also automate removal of the forced online Microsoft account requirement in setup. The created installer boots normally; you can run setup.exe from within Windows to do an in‑place upgrade or perform a clean install. Multiple independent outlets have documented this Rufus workflow and community testing shows it works for many unsupported x64 PCs.A typical Rufus flow looks like this:
- Download the Windows 11 ISO from Microsoft.
- Download and run Rufus. Insert an 8 GB+ USB flash drive.
- In Rufus: pick the ISO, choose “Standard Windows installation” and press Start. When the customization dialog appears, check the boxes to remove the TPM / Secure Boot / RAM checks and (optionally) to remove the required online Microsoft account. Press OK and let Rufus build the USB.
- On the target PC, mount the Rufus USB in File Explorer and run setup.exe (or boot from the USB for a clean install). Choose the upgrade path that keeps personal files and apps if you want to preserve them.
- Rufus doesn’t “remove” TPM/Secure Boot from the hardware; it customizes the installer to skip those checks during setup. If the device later has TPM/Secure Boot present and enabled, Windows can use them normally.
- Rufus’s option to remove the Microsoft account requirement and other “Windows User Experience” tweaks simply pre-configures unattended XML files the setup process reads during install; these are convenience features and alter setup behavior.
Security, Update, and Support Risks (what you must accept)
Installing Windows 11 on hardware that Microsoft deems unsupported isn’t just a technical trick—there are concrete, ongoing risks you must weigh.- Updates are not guaranteed. Microsoft’s official position is that unsupported installs may not receive feature updates, and the company can change update behavior at any time. Users who rely on receiving future security and quality updates should treat updates on unsupported installs as uncertain. This is an important, unverifiable long‑term claim: community reports show many bypassed installs have continued to receive monthly cumulative updates in practice, but that experience varies and is not an official guarantee. Treat any expectation of regular updates on unsupported installs as uncertain.
- Security baseline may be weaker. Microsoft’s hardware requirements (TPM 2.0, Secure Boot) underlie Windows 11 security features like hardware‑anchored encryption and virtualization-based mitigations. Bypassing those checks removes the hardware assurances Windows assumes—this increases exposure to some classes of attacks and may break features dependent on the hardware security root (for example, some anti‑cheat or corporate device attestation features).
- Stability and driver problems. Older CPUs and chipsets may lack microcode or driver support for Windows 11’s newer components. Expect more manual driver hunting and troubleshooting on unsupported hardware; some OEM drivers may not be available.
- Warranty and enterprise policies. For business devices under warranty or managed by IT, running an unsupported configuration can violate support agreements and local security policies. Use unsupported installs only for personal, non‑critical machines where you accept responsibility for ongoing maintenance.
- Regressions may be introduced by future updates. Microsoft may add instruction‑set or microarchitecture checks in future feature updates that make some bypasses no longer work. If your plan depends on long‑term access to updates, buying new hardware or using ESU is a safer choice.
What If You’re Not Ready to Upgrade?
If you decide now is not the time to move to Windows 11—or if your hardware truly cannot meet the baseline—there are reasonable alternatives.- Enroll in consumer ESU through October 13, 2026. Microsoft’s consumer ESU program provides security‑only updates for one year and can be obtained for free by syncing Windows Backup to OneDrive, via redeeming Microsoft Rewards (1,000 points), or by a one‑time paid purchase. This is intended as a bridge, not a permanent solution.
- Stay on Windows 10 but isolate risk. If you keep Windows 10, make sure to maintain antivirus, enable network protections, and isolate sensitive activity (banking, work credentials) to separate machines or VMs. Consider a hardened browser or running risky workflows inside a sandbox or Linux VM.
- Consider alternate OSes or cloud PCs. ChromeOS Flex, Linux distributions, or a cloud desktop (Windows 365 / Azure Virtual Desktop) are valid routes for older hardware. A cloud PC can deliver a supported Windows 11 experience to even very old machines for a subscription fee.
A Practical, Prioritized Checklist (actions to take now)
- Backup everything. Image the drive or at minimum copy Documents, Desktop, and browser/data syncs (OneDrive/Dropbox). Verify the backups.
- Run PC Health Check and note the exact blocking reason(s) (CPU, TPM, Secure Boot, RAM, storage).
- If the block is firmware-related, check UEFI/BIOS and vendor support pages—enable fTPM/PTT and Secure Boot where supported. Update firmware if an OEM update exposes firmware TPM.
- If eligible, use Windows Update or the Installation Assistant for the simplest upgrade.
- If you prefer a USB ISO and the Media Creation Tool fails on Windows 10, download the ISO directly from Microsoft and create media with Rufus (or run the MCT from a Windows 11 host). Microsoft has documented this as the recommended workaround while the MCT regression is fixed.
- If your device is incompatible and you cannot replace it immediately, enroll in ESU to buy time; otherwise, evaluate Rufus or the registry tweak only after confirming robust backups and test installs on spare hardware.
Example: Using Rufus to Upgrade an Unsupported PC (concise walkthrough)
- Download the official Windows 11 ISO from Microsoft.
- Download Rufus and run it on a working PC. Insert an 8 GB+ USB drive (it will be reformatted).
- In Rufus: SELECT the ISO, keep “Standard Windows installation,” then START. When prompted, check the boxes to Remove requirement for 4GB+ RAM, Secure Boot, and TPM 2.0 (and other options if desired). Confirm and let Rufus create the USB.
- On the target PC, open the USB in File Explorer and run setup.exe to perform an in‑place upgrade, or boot from the USB for a clean install. Choose the option to keep files and apps if you want to preserve them.
Final Analysis and Recommendations
- For most users with compatible PCs: use Windows Update or Windows 11 Installation Assistant, or create media with the Media Creation Tool when it works. These keep you on Microsoft’s supported update channel and minimize future headaches.
- If compatibility failures are firmware/configuration issues: fix the firmware settings first (enable fTPM/PTT, turn on Secure Boot). That usually solves the problem without hacks.
- If your PC is truly incompatible and you can’t replace it immediately: enroll in consumer ESU to keep receiving security updates through October 13, 2026, while you plan a permanent migration. The ESU enrollment options (free OneDrive backup route, Rewards redemption, or paid purchase) are detailed on Microsoft’s support pages.
- If you are an enthusiast, hobbyist, or have a spare non‑critical machine and accept the risks: community workarounds—Rufus or the registry method—offer reliable ways to get Windows 11 onto older PCs. Test on spare hardware first, keep verified backups, and be prepared to troubleshoot drivers and manual issues. Do not use these on business‑critical machines.
- Finally, if the Media Creation Tool misbehaves on Windows 10 (a confirmed Microsoft known issue), use the direct ISO download or run the MCT from a Windows 11 machine to create fresh media; Microsoft has acknowledged the problem and published guidance while a fix is prepared.
Upgrading to Windows 11 remains free for qualifying Windows 10 PCs, and there are trusted ways to bring many older machines forward—whether by enabling firmware features, enrolling in ESU as a bridge, or using community tooling when you accept the trade‑offs. Prioritize backups, verify compatibility with PC Health Check, prefer Microsoft’s supported paths when possible, and treat unsupported workarounds as short‑term solutions that require ongoing vigilance and maintenance.
