Microsoft Issues Fix for Windows 11 22H2/23H3 Preview Update Issues

Microsoft has issued a Known Issue Rollback (KIR) to fix issued caused by its latest Windows 11 22H2/23H2 preview update.

“This issue is resolved using Known Issue Rollback (KIR),” the Microsoft Learn website explains. “Please note that it might take up to 24 hours for the resolution to propagate automatically to consumer devices and non-managed business devices and business devices that are not managed by IT departments. Restarting your Windows device might help the resolution apply to your device faster.”

As Laurent noted Monday, users who installed the latest preview update for Windows 11 versions 22H2/23H2, KB5043145, have been experiencing several reliability problems and system reboots. Microsoft will roll the fix for this issue into a future Windows Update, but for now, the KIR will do the trick for individuals. Organizations that installed the dodgy update can use a new Group Policy to deploy the fix as well.

As for KIR, there’s a Microsoft TechCommunity post from 2021 that explains this unusual option.

“Known Issue Rollback is an important Windows servicing improvement to support non-security bug fixes, enabling us to quickly revert a single, targeted fix to a previously released behavior if a critical regression is discovered,” Microsoft’s Eric Vernon writes. “When Microsoft decides to roll back a bug fix in an update because of a known issue, we make a configuration change in the cloud. Devices connected to Windows Update or Windows Update for Business are notified of this change and it takes effect with the next reboot.”
