Many thanks! Great tip!
That is OK, but . . . afterward, you will have missed all the updates to Windows (a horror for Win10), as well as for other utilities, and upgrades that have replaced earlier versions of your most-used main programs.
Sounds like a lot more work than just keeping malware and viruses off your machine by regular housekeeping with available (even free) antivir and anitmal utilities, as well as having a solid firewall.
