Security News > 2021 > March > Microsoft confirms Windows 10 crash issue due to March updates
Update: Microsoft has released out-of-band non-security updates to address the Windows 10 printing crash issue.
Microsoft has confirmed that Windows 10 devices might crash with a Blue Screen of Death when printing under certain conditions after applying the March cumulative updates.
After installing the updates released during this month's Patch Tuesday, "You might receive an APC INDEX MISMATCH error with a blue screen when attempting to print to certain printers in some apps," as Microsoft explains on the Windows 10 health dashboard.
As BleepingComputer reported Wednesday, we have seen a stream of user reports around printing causing Windows 10 to crash with "APC INDEX MISMATCH for win32kfull.sys" BSOD errors since the cumulative updates were released as part of the March 2021 Patch Tuesday.
A similar issue affected Windows 10 devices during the June 2020 Patch Tuesday updates when a bug prevented users from printing.
To resolve the printing issues, Microsoft released out-of-band updates for all impacted Windows users.
