OK….at this point, I am like my dad. I am running Windows 7 on an older machine, and because of hardware limitations, I have not made the jump to Windows 8, 8.5 or 10 and have no plans to do so as long as I have my current system. When I get a new computer, which will most likely be soon, I will cross that new OS bridge at that point.
BUT…. a lot of folks have already made the jump, for better or worse. And the interface and procedures are different from Windows 7.
So take a look at this link, see how to boot Windows 10 in safe mode. Lot’s of stuff to process.
