Microsoft removes Windows 11 update KB5039302, causing reboot loops

Microsoft has removed Windows 11 June update KB5039302 after finding that it caused some devices to restart repeatedly.

Update KB5039302 is the June preview update released this week, allowing consumers and businesses to test new bug fixes and changes before they go live to everyone as part of July’s Patch Tuesday.


In a new message posted to the Windows Message Center, Microsoft indicates that after installing the KB5039302 update, some systems may restart repeatedly.

“After installing the updates released on June 26, 2024 (KB5039302), some devices may fail to start,” Microsoft explains.

“Affected systems may reboot multiple times and require recovery operations to restore normal operation.”

Microsoft says the issue primarily affects devices that use virtual machine tools and virtualization features, such as CloudPC, DevBox, Azure Virtual Desktop. A Windows user also reported on Reddit that the bug was affecting his VMware virtual machines.

The company says it pulled update KB5039302 to investigate the cause of the reboots, and Windows users will no longer see it offered in Windows Update and Windows Update for Business.

Microsoft says that Windows Home edition users are less likely to encounter the issue because virtualization is not commonly used in those environments.

If you are affected by this faulty update, you will need to uninstall it via the Windows 11 Recovery Environment.

After a few unsuccessful reboots, Windows should automatically reboot into the recovery environment as shown below.

Once done, you will be prompted to restart your computer, and now that the update is uninstalled, you should be able to restart Windows 11.
