I receive Ghacks updates routinely. Today I received one which while nothing out of the ordinary for MS, caused me some concern regarding the March 2021 Cumulative Update issued on Patch Tuesday (yesterday).
"The updates patch security issues, all with the second-highest severity rating of important. One of the additional issues that these updates patch is a printing to FILE ports vulnerability. The issue is patched in updates for all versions of Windows, from Windows 7 to Windows 10...According to the reports, updates may cause bluescreens in win32kfull.sys when printing after update installation. Some appear to have mitigated the issue by deinstalling and reinstallation printers on systems, but it does not seem to work for everyone. Others resolved the issue by updating printer drivers." - GHacks
I've delayed my updates for seven days, as MS hasn't even acknowledged the issue yet. I may have to add another seven days to the delay.
You might consider delaying your update, as well.
