This was a mild conspiracy theory through 2015 and 1st half last year when there were major problems with Windows Update for Win 7. Most of us got through all of that, and MS changed their paradigm or model for monthly updates.
Perhaps you could fill us in on your hardware, and describe your problems. I've been through equal troubles with both Win 7 and Win 10. MS would probably wish that everyone would migrate, but they know better. They'll continue their support through 2020 or 2021.
Also -- have you checked your event logs? Made a note of errors and warnings, or tried to resolve them?
Oh . . . almost forgot. What antivirus security program do you use?
