Many Windows found themselves in a quagmire after having installed March’s monthly Windows cumulative updates. The problem is Windows is crashing with so-called blue screen of death (BOD) when attempting to print from Windows apps such as Word, Chrome, Adobe Acrobat and more.
Namely, the issue appears to be impacting printers from Kyocera, Ricoh, Brother and Zebra, among others. After the latest KB5000802 update is installed, according to Microsoft, Windows 10 users can experience “an issue that might cause a blue screen when attempting to print to certain printers using some apps and might generate the error, APC_INDEX_MISMATCH for win32kfull.sys“” The error appears to be related to a mismatched driver and happens when printing from Windows apps.
