Windows 11 KB5014668 update fixes upgrade fails, game crashes

Windows 11

Microsoft has released the optional KB5014668 cumulative update previews for Windows 11 with fixes for issues leading to game crashes and failed upgrades to the latest Windows version.

This cumulative update is part of Microsoft's scheduled June 2022 monthly "C" updates that enables Windows customers to test upcoming fixes before they're released for all users on July 12th as part of the next Patch Tuesday.

Unlike regular Patch Tuesday updates, scheduled Windows non-security preview updates are optional and only provide bug fixes and performance improvements.

Preview cumulative updates released today include:

KB5014668 (Windows 11)
KB5014665 (Windows Server 2022)
KB5014669 (Windows 10, version 1809)

"The preview update for other supported versions of Windows 10 will be available in the near term," Microsoft said.

To install today's preview updates, you have to go to Settings > Windows Update and manually click the 'Check for updates' button. Windows will not install them until you also click 'Download now' because they're also optional updates.

You can also manually deploy them from the Microsoft Update Catalog by searching for KB5014668 or KB5014669 and installing the appropriate package for your platform.

KB5014668 fixes upgrade issues, game crashes

Today's Windows 11 optional update comes with fixes for issues that may cause some games to crash when using specific audio technology.

This cumulative update also patches up a race condition "that might cause an upgrade to Windows 11 (original release) to fail."

It also fixes a bug that could prevent Bluetooth from reconnecting to some audio devices after a device restart.

Last but not least, KB5014668 addresses an issue that might cause Windows 11 (original release) to stop working when installing applications without network connectivity.
