I would just go ahead & upgrade to Windows 10 if I was you. You are getting it free, & Microsoft is only offering the free upgrade for 1 year. After that, you have to pay for it. You're getting a upgraded operating system for FREE....how can you beat that?! From what I hear, it's supposed to combine the best features of Windows 7 & Windows 8, so that will be nice. My ex Craig, who is a computer network engineer, says Microsoft has a tendency to put out 1 bad OS, then a good one....So, since Windows 7 was good, & Windows 8 was bad until Windows 8.1 was released, then Windows 10 should be a good one. I will be upgrading to Windows 10 Professional, since my computer has Windows 7 Professional on it now, I will keep everyone updated if something bad happens.
