Windows 10 Patch Tuesday March 2021: blue screens when printing

Specifically, the patch KB5000802 (KB5000808 in 2004 Y 20H2), a safety replace, is inflicting blue screens on some customers’ computer systems. This safety replace is put in mechanically, so customers who’re experiencing it could not know precisely the place it comes from.

The blue display screen happens when you press print

The failure appears to happen on the time of printing, the place numerous manufacturers could be affected. If the pc has the drivers for the affected printers put in, and also you attempt to print one thing, then the working system hangs. One of the affected customers claims that in his firm there are already 20 confirmed instances from 4 totally different shoppers. The error that seems on the screenshot is «APC_INDEX_MISMATCH for win32kfull.sys«.

Among the affected manufacturers could be Kyocera, Ricoh, Zebra and others. Therefore, evidently the bug is widespread throughout all producers, and doesn’t look like associated to a particular firm. The screenshot happens simply when the print button is pressed, whatever the app (Word, Notepad, and so forth.), and if the system is related to a printer. If we give it to print, however the printer will not be related, then the blue display screen doesn’t happen. Connecting the printer by way of WiFi didn’t clear up something both.

The solely resolution is to uninstall the patch

Therefore, the one resolution out there in the meanwhile is to uninstall the patches KB5000802 and KB5000808 whereas the bug is solved, though in return our pc turns into weak to the vulnerabilities patched this month.

To uninstall them, we simply must go to Settings> Update & safety> View replace historical past. In there we go to the choice to Uninstall the updates, and we select one of many two that we’ve got talked about relying on the model of Windows 10 that we’ve got put in.

Other customers declare that putting in the drivers for Microsoft PCL6 appears to additionally briefly repair the bug. It will in all probability take a couple of weeks for Microsoft to repair this, because it normally takes not less than two weeks to launch the subsequent batch of patches.

If you replace and also you wouldn’t have the bug, it is suggested that you just depart the patches put in, since among the many solved vulnerabilities are these of Microsoft Exchange, which have come to generate complications within the United States White House itself. Through it, scripts have been put in to mine cryptocurrencies.
