So I have an older machine using a core 2 duo 8500 processor with 3.18mhz. I use this maching mostly for social media and email and it has worked fine until microsoft stopped supporting vista. I even upgraded the drive to a nice ssd and the machine boots up pretty fast. But as time goes on, I am having continual problems because of the old software. Have tried some of those cheap windows 7 upgrades you buy on line with no luck. I now either have to go to win 8 or10 or buy a new machine. I would rather keep the machine intact with the existing programs I have there, but am willing to do a clean boot. What are my best options?
