Be aware of these issues in Windows 11 KB5012592 and Windows 10 KB5012599

As part of the April 2022 cumulative updates, Microsoft has released two major cumulative updates - Windows 11 KB5012592 and Windows 10 KB5012599. Both updates contain the same bug fixes and improvements, as Windows 11 is obviously built on top of Windows 10.

Unfortunately, things are not going well for everyone, especially those using Windows 11. The latest updates, numbered KB5012592 and KB5012599, offer a host of bug fixes, stability improvements, an improved Windows search interface, and some small new features like better control over notifications and more.

Since these are mandatory security updates and they install automatically, it’s no wonder many users install them as quickly as possible. If you've updated and your update isn't going as smoothly as expected, you're not alone - some users have reported issues when installing the update, while others have flagged performance issues.

Known issues in Windows 11 KB5012592

According to the official release notes, recovery disks created using the Windows 7-era Backup and Restore tool in Control Panel may not boot in the latest patch . Thankfully, the bug does not affect modern recovery options built into the operating system, and no third-party backup or recovery applications are known to be affected.

On Feedback Hub and Reddit, users are warning that the update may fail to install, with vague error messages such as 0x800f081f, 0xc1900101, and 0x800f0988. The error messages provide no specific details, but the tech giant has previously warned that certain configurations are not "patch-eligible" for various reasons.

In its update connection data, Microsoft warns that computers should have a stable internet connection at least two hours before and six hours after the update. This ensures that Windows updates can be successfully delivered to the device and that it works with Windows 10 as well.

"We have found that devices that have not reached a certain connection time are less likely to successfully update," Microsoft said.

How to fix KB5012592 installation issues

So how to fix KB5012592 installation issues? According to users, in some cases, a simple system restart is enough to resolve Windows update issues.

Also, you can hold down the "Shift" key while clicking the "Shut Down" button. For those who don't know, Shift Shutdown refers to a "complete shutdown" as it forces the operating system to close all applications and log out all users. It also bypasses hybrid shutdown or hibernation (the ability to preserve some data so the system can continue where you left off).

But despite all this pushing, if you find that one or more Windows 11 or Windows 10 PCs don't seem to be updating correctly, you can reset Windows Update or navigate to the Microsoft Update Catalog and download it via .msu package.

In addition to Windows Update issues, users have flagged the following issues with the Windows 11 April 2022 Update:

1. Applications may not start with an error 0xc0000022. This has been fixed with a server-side update.
   
2. Performance issues and a weird bug where the cursor would jump over certain locations on the screen. This has been fixed in newer preview builds.

Known issues in Windows 10 KB5012599

KB5012599 is also plagued by similar issues, including an error that the update may fail to install with 0x800f0831. In the Microsoft forums, users noticed that the cumulative update downloaded successfully, but after a period of inactivity it paused at "Installing 20%" and then moved to 100%.

After getting stuck during installation, Windows Update generates a 0x800f0831 error with a matching installation failure message.

"I have been trying to resolve this issue for the past 2 hours, including running the Windows Update Troubleshooter and many other suggestions, but nothing is working," one users noted in the forum, and others agreed with the findings.

As mentioned at the beginning, if you are having issues with Windows Update and nothing seems to be working, you will need to manually install updates from the Microsoft Update Catalog.

If you have installed the update and are experiencing performance issues or stuttering in games, you can manually uninstall Windows 10 updates through Command Prompt or Settings.
