    Very easy to install ! Not really much of a difference between 8 & 8.1 so nothing more to say.

    Since I built a new home computer, I needed an OS and opted for Win 8.1. Installation went well but had a few problems activating it. After it was running I have made it as desktop friendly (classic appearance) as possible. I’m still not a huge fan of Win 8, but I’m catching on.

    Used it on my new computer build which I will soon make a hackintosh. No bloatware from manufacturers just pure Win 8.1 Pro.

    Not Microsoft’s best OS, but not to bad either.
