Microsoft users BEWARE !!!!!!! I purchased a refurbished laptop last September so I could get one with the Windows7 OS. During updates last week in stuck in the Windows10 upgrade. Damn!! At the end of the upgrade I declined the "terms and conditions" and it said "o.k., we'll put it back to the original OS. Well, because I had a "legal" version of Windows7 Professional from a third party, it didn't reload and crashed my laptop. After an hour on the phone with Microsoft they said my only option (when I was able to understand the non-English speaking rep) was to have them repair it for $99 or a one year maintenance agreement for $199. Your @ss !!! I received a disk with Windows7 OS from the remanufacture but it didn't totally restore to what I had before. No drivers for my 3.0 USB ports, etc. It is now on it's way to the re manufacturer (under warranty-free shipping) to be put back together.
If you don't want Windows10, be very cautious of upgrades they want to put on your computer. Read each step carefully. When I get the computer back I'll have to totally restore all files and programs as before, more hours of wasted time I could be flying. With 50% of Microsoft users still running Windows7 you'd think they could take a hint. Larry Flesner
