As just a general comment, I agree with Bob that there's nothing wrong with it as long as you install the free Classic Shell. That Metro stuff makes zero sense to me and a whole lot of other folks, but if you install Classic Shell, you can forget Metro.
I also agree as another poster says, I wouldn't pay to upgrade to 8 from 7 without some good reason, and I don't really know of what that might be. There's nothing in 8 that I couldn't do with 7, especially given that Windows 10 will be out sometime this spring. I've been a Windows 10 tester since early October, and it runs all my old software, it has the Start menu back, and it's been rock solid on my test computer. YMMV.
OTOH if you're still running XP or even Vista, I'd say it makes sense to upgrade, but again Windows 10 this spring might be a better alternative.
Good luck.
how much you will rate windows 8 for professional people.
