Microsoft Re-releases Troubled Patch for Windows 11, Excluding Virtualization Devices

Earlier, Microsoft released a preview update (KB5039302) for Windows 11 in June, but many users, especially professionals and developers, experienced system crashes after installation, prompting Microsoft to halt the update's rollout.

After initial investigation, Microsoft confirmed that the update caused errors in virtualization software, such as virtual machines, leading to system issues. Affected software includes VMware, CloudPC, DevBox, and Azure Virtual Desktop.

If the system does not have these virtualization software or nested virtualization environments installed, the update will not cause any issues. Due to this problem, Microsoft stopped pushing the update to avoid further problems.

Now, Microsoft has re-released the update, but surprisingly, it has excluded virtualization devices. This means that the issue has not been fully resolved, and users with virtual machines and virtualization environments installed will not receive the update.

The Patch Tuesday for this month is on July 9th, leaving Microsoft only a week to resolve this bug. If the bug is not fixed, it is likely that Microsoft will continue to temporarily block the update for devices with virtual machines installed, as it cannot knowingly push a problematic update that causes widespread system crashes.

Finally, it's worth noting that preview updates have a testing nature, and users are not recommended to select "Download and install updates as soon as they are available" in Windows Update. If this option is selected, any preview updates released by Microsoft will be received and installed automatically by the system.
