First. If it ain't broke, don't fix it. Now for what I heard. The free upgrade ends I think around the end of this month, so if you are going to do it now is the time. I read that Windows 8.1 had issues and it was worth upgrading, but Window 7 and 8 were good. I personally, don't like what I see in 10. I don't like the lay-out and invasion of more privacy. If you do upgrade, be sure you back-up everything. There also is an out, that is supposed to work so one can go back to the old version you had.
Good luck, what ever you decide. I am sticking with W-7.
