Latest Windows 10 update seems to be causing BSODs when printing

If your PC is suffering from a Blue Screen of Death (BSOD) while attempting to print, a recent Windows update from Microsoft may be to blame.

According to reports from Windows Latest and other sites, all referencing a Reddit thread, users started experiencing BSODs shortly after installing Windows Update KB5000802, which was installed on March 9.

While the Reddit thread specifically mentions BSODs occurring in conjunction with Kyocera printers, Windows Latest reported that it had heard of similar results with printing activity from many different makes and models, including Ricoh. When the BSOD occurs, users may receive the “APC_INDEX_MISMATCH for win32kfull.sys” error message.

PCWorld has contacted Microsoft but received no comment at press time. However, after the publication of this article, Microsoft has confirmed the problem. “We are working to resolve an issue affecting a subset of customers using certain printers”, a company representative said via email.

Rolling back the patch appears to resolve the issue. Some Reddit thread users reported that they were able to uninstall the Windows 10 hotfix, but others did not.

Unfortunately, because the update in question was a security update, rolling back the patch may expose users to a security issue. If necessary, however, users can uninstall the fix by following these steps:

1. Open the Windows Settings menu, then navigate to Settings> Update & Security> Windows Update.
2. Click on View update history.
3. Click on Uninstall updates link, and then search for the update in question.
4. Once you’ve found it, click Uninstall.
