bsod

I struck this in the wild today. A Windows update is killing printing for Type 3 printers. The result is a BSOD stop code APC_INDEX_MISMATCH in win32kfull.sys. The fix that worked for me came from here: https://docs.microsoft.com/en-au/windows/release-health/status-windows-10-2004#1570msgdesc

Really scratching my head on this problem. Hoping someone has insight. Thank you in advance to anyone for your help and time with this issue. Problem: BSOD dump files point to iUSB3Hub.sys as the breaking point after enabling BIOS option: External USB ports. Steps taken after this problem...
