Skipping Windows updates usually will not cause an immediate crash or make a PC visibly fail overnight. The more consequential change is quieter: a machine remains on an older security baseline while Microsoft, security researchers, and attackers continue to learn what the newer code fixes. BGR’s overview of the risks gets that central point right, but it treats “Windows updates” too broadly for a decision that should be made differently by home users, small businesses, and managed IT environments.
For a current Windows 11 PC, the practical rule is simple: do not treat monthly security and quality updates as optional features. Delay a feature upgrade if necessary, avoid optional preview patches unless they fix a problem you actually have, and manage drivers separately where possible. But leaving the regular cumulative update stream behind for weeks or months creates a widening gap that anti-malware alone cannot close.
Microsoft’s own servicing documentation makes the distinction clear. A monthly quality update includes security fixes alongside reliability and bug fixes, and each new one is cumulative. A PC that skips July’s update but installs August’s generally receives July’s fixes too. A PC that stops updating entirely does not merely miss a string of cosmetic changes; it misses the current aggregate of Microsoft’s fixes for its version of Windows.
The danger in skipping updates is not that every missed patch exposes a dramatic remote takeover bug. Most vulnerabilities require a particular configuration, user action, local access, or a second weakness to become useful. But Windows is used across home networks, workplaces, schools, remote-access setups, printers, file shares, browsers, VPN clients, and domain environments. The more months a machine falls behind, the more opportunities there are for a relevant flaw to line up with its configuration.
Attackers also do not need a newly disclosed Windows flaw to affect an unpatched system. Older vulnerabilities remain useful when they are common, reliable, and present on devices that have been forgotten. CISA’s Known Exploited Vulnerabilities catalog exists specifically to distinguish theoretical bugs from those with evidence of real-world exploitation. That catalog is a better priority signal for administrators than panic over every new CVE number, but it does not help a device that never receives the update containing the fix.
The key operational point missing from the usual “just update” advice is that security is not an all-or-nothing choice between immediate installation and permanent refusal. Microsoft supports controlled deferrals for organizations, and its Windows Update client policies distinguish feature updates from quality updates. Administrators can stage deployment through test, pilot, broad, and critical-device rings; Microsoft’s own example uses short quality-update delays while allowing much longer feature-update deferrals.
That is a recognition that patching carries change risk. It is not a license to create a permanent exception list.
The upside is recovery: installing the latest monthly cumulative update generally brings a supported Windows build current without manually applying every missed KB in sequence. The downside is that a user who distrusts a single nonsecurity change may respond by blocking the entire package and, with it, the security payload.
That is why optional preview updates deserve different treatment from the regular monthly security release. Preview releases are intended to validate nonsecurity fixes before those fixes are incorporated into a later cumulative update. If a PC is stable and no listed fix solves a real problem, there is little reason for a home user to install a preview simply because it is offered. That is a much narrower and safer form of caution than disabling Windows Update outright.
Driver updates are another separate category. Microsoft’s update policies allow managed environments to control whether drivers arrive through Windows Update, and IT departments with specialized storage controllers, CAD workstations, industrial hardware, or line-of-business peripherals often need a vendor-tested driver process. A problematic driver package should lead to driver controls and hardware-specific testing, not a decision to abandon OS security servicing.
Claims that Windows updates inherently slow down a computer also need more evidence than a before-and-after impression. A major feature update can expose an aging SSD, low free storage, insufficient RAM, startup bloat, a failing driver, or software that is no longer compatible. Monthly servicing can occasionally introduce regressions, too. But a sustained performance decline is a troubleshooting problem, not proof that the security-update channel should be shut off.
Rapid7 reported that public proof-of-concept exploits began circulating on June 29, 2021, initially amid confusion with the separately tracked CVE-2021-1675. Rapid7 documented that the exposed Windows Print Spooler functionality could permit authenticated attackers to execute code with SYSTEM-level privileges in affected circumstances. Microsoft then clarified the issue under CVE-2021-34527, and released emergency out-of-band updates on July 6 rather than waiting for the next standard Patch Tuesday.
The record is more complicated than a clean patch-success story. CISA’s July 2021 alert noted that the first out-of-band fixes addressed remote code-execution variants and cited CERT/CC’s concern about a local privilege-escalation path. Rapid7 also found configuration-dependent conditions where public exploit code could remain effective after the initial patch, particularly around Point and Print settings. Microsoft subsequently said its update worked as designed against the known printer-spooling exploits and issued guidance restricting printer-driver installation.
That is not an argument against patching. It is the opposite: PrintNightmare showed why administrators must patch, confirm that the update actually deployed, review the vendor’s mitigation guidance, and test the business function involved. On domain controllers and systems that do not need printing, disabling the Print Spooler was a defensible temporary mitigation. On print servers, the answer required more care because applying restrictions could affect legitimate driver deployment and printing workflows.
The broader lesson is that a patch closes a defined portion of a known exposure; it does not replace configuration management, least privilege, network segmentation, or asset inventory. An unpatched device has the original exposure plus whatever later exploitation knowledge becomes public. A patched but poorly configured system may still need additional work. Those are different risks, and they require different responses.
Microsoft’s Consumer ESU program provides critical and important security updates for eligible Windows 10 22H2 devices through October 13, 2026. It does not add features, ordinary product improvements, or technical support. For someone keeping a compatible Windows 10 computer in service temporarily, ESU is a risk-reduction bridge, not a return to full support. For an organization, Windows 10 ESU licensing and servicing terms differ by program, so consumer enrollment should not be assumed to cover business endpoints.
This creates an uncomfortable but concrete distinction. A Windows 10 PC can be stable, useful, and still be a security liability if it has stopped receiving fixes. Stability measures whether the machine works today; support status determines whether newly discovered defects will be corrected tomorrow.
For IT teams, the defensible model is staged deployment with visibility. Keep an inventory of Windows versions and update status, deploy monthly quality updates first to representative test devices, then to pilot and production rings on a defined schedule. Treat CISA-known exploited vulnerabilities, Microsoft emergency releases, internet-facing systems, identity infrastructure, and endpoints with elevated users as reasons to compress that schedule.
The bad outcome is not a carefully managed delay with testing and a deadline. It is an exception that becomes permanent because nobody owns it. Once a Windows device no longer has a supported version, a current cumulative update, or a compensating control, it is no longer merely “avoiding annoying updates.” It is operating outside the security baseline Microsoft is actively maintaining.
Microsoft’s own servicing documentation makes the distinction clear. A monthly quality update includes security fixes alongside reliability and bug fixes, and each new one is cumulative. A PC that skips July’s update but installs August’s generally receives July’s fixes too. A PC that stops updating entirely does not merely miss a string of cosmetic changes; it misses the current aggregate of Microsoft’s fixes for its version of Windows.
The real cost is an outdated security baseline
The danger in skipping updates is not that every missed patch exposes a dramatic remote takeover bug. Most vulnerabilities require a particular configuration, user action, local access, or a second weakness to become useful. But Windows is used across home networks, workplaces, schools, remote-access setups, printers, file shares, browsers, VPN clients, and domain environments.

That is a recognition that patching carries change risk. It is not a license to create a permanent exception list.
Cumulative updates make selective avoidance harder
Windows Update’s modern cumulative model reduces fragmentation but also means users cannot reliably choose “security fixes only” while declining every change they dislike. The same monthly package commonly carries security remediation, reliability fixes, and other servicing changes. Microsoft designed this approach to keep devices from settling into countless unsupported combinations of partially installed patches.The upside is recovery: installing the latest monthly cumulative update generally brings a supported Windows build current without manually applying every missed KB in sequence. The downside is that a user who distrusts a single nonsecurity change may respond by blocking the entire package and, with it, the security payload.

Monthly servicing can occasionally introduce regressions, too. But a sustained performance decline is a troubleshooting problem, not proof that the security-update channel should be shut off.
PrintNightmare shows both why patches matter and why patching needs verification
BGR uses PrintNightmare, tracked as CVE-2021-34527, as an example of why delaying updates is risky. The incident remains useful, but its timeline also demonstrates why “install the patch and forget it” is not sufficient administrative advice.Rapid7 reported that public proof-of-concept exploits began circulating on June 29, 2021, initially amid confusion with the separately tracked CVE-2021-1675. Rapid7 documented that the exposed Windows Print Spooler functionality could permit authenticated attackers to execute code with SYSTEM-level privileges in affected circumstances.

An unpatched device has the original exposure plus whatever later exploitation knowledge becomes public. A patched but poorly configured system may still need additional work. Those are different risks, and they require different responses.
Windows 10 has turned update avoidance into a support-status problem
On August 6, 2026, the sharpest update question is not confined to Windows 11. Windows 10 Home and Pro reached the end of free support on October 14, 2025. A Windows 10 version 22H2 PC that was not enrolled in Microsoft’s Consumer Extended Security Updates program has already been outside the normal stream of free Windows security fixes for nearly ten months.Microsoft’s Consumer ESU program provides critical and important security updates for eligible Windows 10 22H2 devices through October 13, 2026. It does not add features, ordinary product improvements, or technical support.

Stability measures whether the machine works today; support status determines whether newly discovered defects will be corrected tomorrow.
A better policy than “always update immediately” or “never update”
Home users should leave automatic security updates enabled, let Windows install the current monthly cumulative update, and schedule the restart at a predictable time. Before a major feature update, back up important files and check available storage, drivers, and software compatibility. If a regular cumulative update causes a documented problem, uninstall or pause it briefly, watch Microsoft’s release-health notices, and install the corrected or superseding update rather than remaining indefinitely behind.For IT teams, the defensible model is staged deployment with visibility. Keep an inventory of Windows versions and update status, deploy monthly quality updates first to representative test devices, then to pilot and production rings on a defined schedule.
