Microsoft has released the KB5000842 non-security preview update for all editions of Windows 10, version 20H2, and Windows 10, version 2004, with fixes for system freezing and activation issues.

After installing this cumulative update, you may experience issues with the system and user certificates getting lost if updating from Windows 10 1809 or later versions using outdated install media.

More details regarding the types of updates Microsoft releases each month are available in the Windows 10 update servicing cadence primer.
With the KB5000842 monthly release preview update, Microsoft addresses an issue that might cause systems running Windows 10 2004 to stop responding during hybrid shutdowns.

This cumulative update also fixes bugs causing devices to stop working and generating 0xC9 error codes, and heap leak triggering high memory consumption in explorer.exe.

Microsoft also addressed a Windows activation issue impacting Windows 10, version 2004 systems after installing last month's KB4598291 preview update that fixed device deactivation and freezing issues.

Last but not least, the update removes the out-of-support Microsoft Edge Legacy and installs the new Microsoft Edge. Microsoft announced last month that the Windows 10 April updates will remove Edge Legacy permanently.

Other highlights included in this update:
  • We fixed an issue that might cause the cluster network interface to stop working for a short time. As a result, the network interface controller (NIC) is marked as failed. When the network is operational again, the system might not detect that the NIC is working and the NIC remains in a failed status.
  • Addresses an issue that causes a system to stop working when no Trusted Platform Module (TPM) is present in the system. The error code in TpmTasks.dll!TrackTPMStateChanges is c0000005.
  • Informs users when a child account in the Family Safety plan has administrative privileges.
  • Updates an issue that causes a device to stop working if you delete files or folders that OneDrive syncs.
  • Addresses an issue that might cause File Explorer and other applications to stop responding for several minutes. This issue occurs after a client reconnects to the corporate network and attempts to use mapped drives to access file shares on the corporate network.
