Several users are reporting installation issues and crashes when attempting to install Windows 10’s latest optional update. As spotted by WindowsLatest, customers on the Feedback Hub and Reddit are reporting issues with KB4541335.
The problem appears to occur for those on Windows version 1903 and 1909, with some receiving ‘There were problems installing some updates’ messages, and others experiencing freezing and other instabilities during mouse or keyboard input.
“The 2020-03 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4541335) gets to about 90% before it says “We couldn’t complete the updates Undoing Changes” then it just restarts and doesn’t update. I have tried to install the update 8 times over the course of about 2 weeks and the same thing happens every time,” explains one Reddit user.
“It reached 74% installed and then anything I’d send input to would stop working,” said another, according to WindowsLatest.
Others say they’re unable to play games like Bleeding Edge or the Halo Masterchef Collection on Steam. This issue is caused by a known problem with Windows 10 proxies that is affecting applications that use WinHTTP or WinInet.
Unfortunately, those wanting to jump into the Microsoft published shooters may have to wait a little while longer. Though the company is working on a fix, it says it won’t roll out until early April. You may get some relief by restarting your PC, but this appears to be only a temporary fix at this time.
The installation issues sadly don’t appear to have a fix just yet, but it’s worth noting that this is an optional update. It holds minor bug fixes and improvements and can be skipped until it rolls out with Next month’s Patch Tuesday, which will also contain a fix for a critical security flaw.
