You can get legitimate Window’s 10 keys on eBay for under $10. All three of my computers have Windows 10 Pro keys I obtained that way. When I reinstall Windows 10 the key is automatically restored, which proves it is registered with Microsoft.
I bought a new puter on sale at Christmas time with Win 10 in it. I need to find some kid that can configure everything for me.
Gonna use Win 7 as long as I can.
