Microsoft has acknowledged a new issue in its Patch Tuesday update for Windows 10 versions 2004 and 20H2 released earlier this week. Indeed, some users who have installed the patch have been encountering BSODs when trying to print files from Microsoft Word and other apps.
In its updated release notes, Microsoft explained that "after installing this update, you might receive an APC_INDEX_MISMATCH error with a blue screen when attempting to print to certain printers in some apps. According to the numerous reports spotted by Windows Latest on Reddit, the issue seems to be affecting printers from Kyocera, Ricoh, and Zebra.
It's hard to know if these printing-related BSOD issues are affecting many Windows 10 users. While Microsoft is already working to fix these issues, affected users unable to use their printers may want to uninstall the patch in the meantime. To do so, you’ll need to open Windows Update in Settings, go to View update history, and then choose "Uninstall updates."
This month's Patch Tuesday update was notable as it removed the now-unsupported legacy Edge browser from the OS. If you had yet to install the new Chromium-based Edge, this update will also automatically install it on your PC. We hope that a fix for the BSOD issues is coming later this month, but let us know in the comments if you've been affected.
