Last week, Microsoft released the KB5041585 cumulative update for Windows that packed together a bunch of improvements and security patches along with fixing the BitLocker BSOD issue.
But in what appears to be a trend this year, this Windows update comes with some serious side effects.
According to IT blog Borncity (German), patch KB5041585 can cause Windows 11 PCs to crawl to a halt due to skyrocketing CPU usage. And according to Windows Latest, the patch can even fail to install altogether on some PCs. Complaints from affected users can be found across social media, such as in this Reddit thread.
Windows Latest quotes several affected users, including this one:
“This problem started as soon as the updates installed this morning. Any slightly heavy applications, such as Adobe Photoshop or Audition, or games like Diablo and World of Warcraft keep crashing, and this is the only change this PC has experienced since last month’s updates. Dialog box says ‘XXX program is using too much memory and must shut down’ even though Task Manager says I am only using 18% and there’s over 900GB free space on the drive. This has never been a problem until today.”
Windows Latest continues: “KB5041585 has also led to high CPU usage, with some users reporting that their CPU is constantly at 100%, causing everything to run slowly and leading to frequent timeouts.”
What to do if you’re affected
As of right now, the only guaranteed way to resolve these issues is by going to Settings > Windows Update > Update history, then scroll all the way down and select Uninstall updates, then click Uninstall next to the item listing for the KB5041585 update.
Alternatively, you might find some relief by disabling Control Flow Guard. You can do this by launching Windows Security, selecting App & browser control in the left navigation, scrolling down to Exploit protection, clicking on Exploit protection settings, and then changing the Control flow guard (CFG) setting to Off by default.
Microsoft is rumored to be aware of the problem and working on a solution. However, the official support page for this patch still states “Microsoft is not currently aware of any issues with this update.”
