Last night on my work computer I got the little pop-up in the corner asking me to reserve a free update to Windows 10. Sounds good in theory, but should I do it? I use a lot of software that was designed for XP, stuff that I had to disable UAC completely in order to install. On Windows 7 right now BTW. Didn't see it right off in the FAQ from M$, but are these "free" upgrades apples to apples, i.e. Win 7 Pro -> Win 10 Pro, or am I going to get the starter version bullsh!t? Any advice appreciated.
