Microsoft is now telling us NOT to install this past week's security update. Roughly half the PC's out there experienced (me too) loss of printing ability or BSOD (blue screen of death). They're now saying if you did update to undo it (Win 10 allows you to uninstall updates) until they get this fixed. 

To see what version of Win 10 your on:

1. Press the Windows Key and R to bring up the Run window.
2. Type winver in the text field and press Enter.
