Microsoft has confirmed that its March 2021 updates are causing Windows 10 devices to crash with the Blue Screen of Death (BSOD) when printing.
After installing KB5000802 a user might receive an APC_INDEX_MISMATCH error with the Blue Screen of Death when attempting to print to certain printers in some apps. It is reported that both client and server Windows versions are affected by this cumulative update.
In the event that you would have encountered the BSOD, the following steps are recommended:
If youre unable to uninstall the patch via Control Panel, you can also use the following Command Prompt or PowerShell command to remove the patch manually:
wusa /uninstall /kb:[id]
In the above command, you would need to replace the KB ID with the one that you wish to uninstall.
If youre on v2004 or 20H2, the command would be wusa /uninstall /kb:5000802.
For version 1909/1903, the command is wusa /uninstall /kb:5000808.
The Guyana National CIRT would like to remind users and administrators that it is important to test patches before applying, to always backup data and critical systems before applying patches.
