In less than two weeks, Microsoft will stop shipping monthly security patches to Windows 11 version 24H2 Home and Pro editions. If your PC is still on 24H2 after October 13, 2026, it will stop receiving fixes for newly discovered security holes — and the clock is already ticking for most home and small-business machines in York County.
What Microsoft announced
On October 13, 2026, Windows 11, version 24H2 Home and Pro editions will reach end of updates. After this date, devices running these editions will no longer receive monthly security and non-security preview updates containing protections from the latest security threats. Enterprise and Education editions remain supported until October 12, 2027.
Microsoft has been pushing eligible 24H2 machines forward automatically. Devices running Home and Pro editions of Windows 11, version 24H2 that are not managed by IT departments will receive the Windows 11, version 25H2 update automatically. In practice, that means most consumer PCs will roll to 25H2 on their own — but not all of them will, and some will stall partway through for the usual reasons: low disk space, driver conflicts, interrupted installs, or a drive that is starting to fail.
How to check which version you have
Press the Windows key, type winver, and hit Enter. A small box will show your Windows version. If it says Version 24H2, your PC is on the version that stops getting patches on October 13. If it says 25H2, you're already on the current release and no action is needed. Windows 11, version 25H2 is the latest version of Windows available.
If you're on 24H2 and Windows Update hasn't offered 25H2 yet, go to Settings → Windows Update and click Check for updates. The upgrade is delivered as a normal cumulative update and typically installs in a few minutes on a healthy system.
What happens if you ignore the deadline
Your PC will keep working. But without monthly patches, any new vulnerability discovered after October 13 will remain open on your machine indefinitely. That is exactly the window attackers look for — unpatched consumer PCs are the easiest targets for ransomware, banking trojans, and info-stealers. If your machine does get hit, cleanup usually means a full malware and ransomware removal job, and in bad cases a wipe-and-reinstall where any un-backed-up files are gone.
This is also a good moment to check that your backups are actually running. Windows' built-in File History has been glitchy on recent updates, so don't assume it's working — open it and confirm the last backup date. If a drive has already failed, pulling files off a dead disk is a separate job that gets harder the longer the drive sits.
If the 25H2 upgrade won't install
A stuck feature update is the most common reason a PC lands on our bench this time of year. The usual culprits are a nearly full system drive, a flaky hard drive that can't complete the copy, insufficient RAM to stage the install, or a corrupted update component. In many cases the fix is straightforward — clear out old update files, run the Microsoft upgrade assistant manually, or swap a slow spinning drive for an SSD. An SSD and memory upgrade often solves both the update problem and the "my computer is slow" complaint in one visit.
If the machine won't boot after a failed update, that's a repair-shop problem, not a DIY one — forcing more update attempts on a half-installed system can make the files on the drive harder to recover.
Note on Windows 10 users
This deadline is specifically about Windows 11 version 24H2. Windows 10 users are on a different track: The Extended Security Updates (ESU) program for Windows 10 provides customers with a more secure option to continue using their Windows 10 PCs after October 14, 2025, while they transition to Windows 11. The ESU program helps reduce the risk of malware and cybersecurity attacks by providing access to critical and important security updates as defined by the Microsoft Security Response Center (MSRC) for devices running Windows 10, version 22H2. You can enroll in ESU any time until the program ends on October 12, 2027. If you're already enrolled, your coverage will automatically continue through that date—no action needed.
