Microsoft has tacitly confirmed that the mandatory Windows 11 24H2 updates from past months negatively impacted the operating system’s stability, which is bad timing for the company who recently claimed that Windows 11 is the “most reliable” version of Windows ever.
The issues continued with mandatory updates KB5060842 and KB5063060 in June, which brought their own problems. Windows 11 users might’ve seen error messages such as 0x800f0922, 0x80070002, 0x80070306 or 0x800f0991 when they tried to install the updates.
According to Windows Latest, system stability issues include: games like Fortnite randomly restarting on affected PCs, Windows taskbar freezes, incorrect Windows Firewall events, and FPS drops and performance hits in games like Counter-Strike: Global Offensive.
Microsoft has now quietly confirmed these problems. In an addendum to the currently optional preview update KB5062660, Microsoft writes:
[Stability issue] This update addresses an issue observed in rare cases after installing the May 2025 security update and subsequent updates causing devices to experience stability issues. Some devices became unresponsive and stopped responding in specific scenarios.
[Windows Firewall] Fixed: This update addresses an issue found in Event Viewer as Event 2042 for Windows Firewall with Advanced Security. The event appears as “Config Read Failed” with the message “More data is available.” For more information about this issue, see “Error events are logged for Windows Firewall” in the Windows Health Dashboard.
No details are provided on the exact reasons for the problems, but you can address these issues by installing update KB5062660.
How to get update KB5062660
Update KB5062660 is currently still an optional update that Microsoft does not yet install as standard on all Windows computers. It will be released for all Windows computers on Patch Tuesday in August.
If you’re experiencing any of the problems described above and therefore want to install the optional update to fix those problems, you must do so manually via Windows Update or the Microsoft Update Catalog.
Microsoft has recently committed to improving Windows 11 performance and made moves to improve Windows 11 stability with stricter driver standards. Hopefully the company will hold true to its words and these sorts of issue-laden Windows 11 updates will become a thing of the past.
