" Microsoft has released optional cumulative update previews for Windows 10 versions 20H2, 21H1, and 21H2, fixing slow file copying and applications crashing due to Direct3D issues.

Today's KB5014023 update is part of Microsoft's scheduled May 2022 monthly "C" updates which allow Windows customers to test bug fixes and performance improvements before the general release on June 15 during Patch Tuesday. "

Fixes app crashes, file copying, memory leak issues​

Today's optional update fixes several issues that might trigger various problems or cause some Windows applications to crash.

This cumulative update fixes a known issue affecting specific GPUs that could "cause apps to close unexpectedly or cause intermittent issues that affect some apps that use Direct3D 9."

Microsoft also fixed an issue that might cause file copying to be slower and one more that would prevent BitLocker from encrypting when using the silent encryption option.

KB5014023 addresses other known issues impacting Windows systems in use 24/7, leading to a memory leak and causing the deduplication driver to deplete all physical memory and cause the machine to stop responding.

Last but not least, after applying today's preview update, Windows systems will no longer stop responding when users sign out when Microsoft OneDrive is in use.

What's new in today's Windows update preview​

After installing the KB5014023 non-security cumulative update preview, Windows 10 21H2 will have the build number changed to 19044.1741.

The Windows 10 update preview includes a lot more quality improvements and fixes, including:
  • Addresses an issue that causes a yellow exclamation point to display in Device Manager. This occurs when a Bluetooth remote device advertises the Advanced Audio Distribution Profile (A2DP) source (SRC).
  • Addresses a rare issue that prevents Microsoft Excel or Microsoft Outlook from opening.
  • Addresses a known issue that might prevent recovery discs (CD or DVD) from starting if you created them using the Backup and Restore (Windows 7) app in Control Panel. This issue occurs after installing Windows updates released January 11, 2022 or later.
