Microsoft has released the optional KB5055612 preview cumulative update for Windows 10 22H2 with two changes, including a fix for a GPU paravirtualization bug in Windows Subsystem for Linux 2 (WSL2).

The KB5055612 cumulative update preview is part of Microsoft’s “optional non-security preview updates” schedule, typically released at the end of every month. This update allows Windows admins to test upcoming fixes and features that will be released in the upcoming May Patch Tuesday.

Unlike Patch Tuesday cumulative updates, this preview update does not include security updates.
