Emergency fix for recent Windows 11 update by Microsoft

Key Points

• Support Ended: Microsoft has officially ended support for Windows 10, encouraging users to upgrade to Windows 11.
• Update Issues: The latest Windows 11 update has caused various issues with applications and peripherals.
• Fix in Progress: Microsoft is working on a patch for the problems caused by Windows 11 KB5066835.
• Market Share: Windows 11 now holds nearly 50% of the market share, while Windows 10 retains 40% despite the end of its support.

Just last week, Microsoft officially ended support for Windows 10, pushing users to upgrade to its latest operating system Windows 11. That makes the timing of a recent Windows 11 issue very awkward for Microsoft.

Unfortunately, Microsoft’s most recent Windows 11 update appears to have caused problems with numerous different applications and hardware peripherals, according to multiple reports from different outlets, including our sister site, CNET. Many devices using Windows 11 will now require a follow-up emergency update to fix issues caused by the previous mandatory update.

The October Windows 11 update “breaks localhost (127.0.0.1) HTTP/2 connections,” according to Windows Latest, which also listed a number of issues that users are facing. For example, apps that were hosted locally were no longer able to connect to the network. Windows users were also finding that some hardware by Logitech was no longer working on their PCs. In addition, some users reported that their mouse and keyboard wouldn’t work in WinRE (Windows Recovery Environment) and that File Explorer documents wouldn’t open in the Preview pane due to a false security issue.

Microsoft has since indicated that a fix is on the way in a subsequent update for issues with Windows 11 KB5066835. The company says a patch is rolling out and users should continually check for an update. However, it could take more than 48 hours for the update to finally show for some users.

Mashable previously reported on one of the last updates to Windows 10, which caused issues that included frame rates dropping in games like Fortnite, making them near unplayable.

Windows 11 was released in 2021 and now holds nearly 50 percent of the market share. Its predecessor, Windows 10 was first released to the public in 2015 and still holds 40 percent of the PC market share, regardless of the fact that Microsoft ended support for the operating system earlier this month.

As Microsoft looks to move those who have still yet to update their operating system to Windows 11, this latest update bug couldn’t have come at a worse time. Microsoft is certainly looking to get that fix out to everyone as soon as possible.
