Watch out for these issues in Windows 11 KB5012592 & Windows 10 KB5012599

As part of the
April 2022 cumulative updates, Microsoft published two
major cumulative updates – Windows 11 KB5012592 and Windows 10
KB5012599. The two updates contain identical bug fixes and
improvements because Windows 11 is apparently built on top of
Windows 10.

Unfortunately, things aren’t going smoothly for everyone,
particularly those who are on Windows 11. The latest updates,
numbers KB5012592 and KB5012599, offer lots of bug fixes,
stability improvements, an improved interface for Windows
Search, a couple of small new features like greater control
over notifications, and so on.

Since these are mandatory security updates and they install
automatically, it’s no wonder that many users have them
installed as quickly as possible. In case you’ve already
updated and the 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

As per the official release notes, recovery disks created using
the Windows 7-era ‘Backup and Restore’ tool in Control Panel
might fail to launch in the latest patch. Thankfully, the bug
does not affect the modern recovery options built into the
operating system and no third-party backup or recovery apps are
known to be affected.

On Feedback Hub and Reddit, users warned that the update could
fail to install with vague error messages like 0x800f081f,
0xc1900101 and 0x800f0988. These error messages do not offer
specific details, but the tech giant previously warned that
some configurations are not “patch-compliant” due to various

In its Update Connectivity data, Microsoft warned that the
computers should have a stable internet connection for a
minimum of two hours of pre-update and six hours of post-update
time. This ensures that a Windows Update can be successfully
delivered to the device and it also applies to Windows 10.

“What we found is that devices that don’t meet a certain amount
of connected time are very unlikely to successfully update,”
Microsoft said.

How to fix KB5012592 installation issues

So what can be done to fix KB5012592 installation issues? As
per users, a simple system reboot is enough to address Windows
Update issues in some cases.

Additionally, you can hold the ‘Shift’ key when clicking on the
Shutdown button. For those unaware, Shift + Shutdown refers to
a ‘full Shutdown’ as forces the OS to close all apps and
signout all the users. It also bypasses hybrid shutdown or
hibernation (a feature that retains certain data so the system
can pick up from where you left).

However, despite all this push, if you find that one or more of
your Windows 11 or Windows 10 PCs seems to be failing to update
properly, you can reset Windows Update or navigate to Microsoft
Update Catalog and install any update manually by downloading
the .msu package.

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

  1. A bug where apps may fail to start with
    0xc0000022. This has been fixed via a server-side

  2. Performance issues and a weird bug where the cursor would
    skip certain spots on the screen. This has been fixed in a
    newer preview build.

KB5012599 is also plagued with similar issues, including a bug
where the update could fail to install with 0x800f0831. In a
Microsoft forum, users noted that the
cumulative update is downloaded successfully, but then after a
period of inactivity, it pauses at ‘Installing 20%’ and later
moves to 100%.

After getting stuck in the installation process, Windows Update
generates the 0x800f0831 error with a matching failure to
install message.

“I have spent the last 2 hours trying to fix this problem,
including running the Windows Update Trouble Shooter plus a
host of other suggestions, but nothing works,” one user noted
in the forum and others have echoed the findings.

As mentioned at the outset, if you run into Windows Update
issues and nothing seems to be working, you need to manually
install the update from Microsoft Update Catalog.

If you’ve already installed the update and there are
performance issues or stuttering in games, you can
uninstall Windows 10 updates manually via Command Prompt or
