I'll never know. I won't be getting on the Microsoft train cars that are headed for the work camps and gas ovens.
I have modified XP so it cannot access my high speed connection and am running a Linux VM to do internet stuffs. So far, works like a champ. I'll use XP for my offline utility work.
Good luck with the Lenovo.
Thank you. It took forever for Win8.1 to download and install. So far, so good, and that is finished.
