I have some questions or concerns about Windows 8.1 update for free. I suppose it is like a service pack of previous versions of Windows. Though I do remember reading that Support for Windows 8 vanilla will end in a few years. And there are things that I can't get on my Windows 8 Pro platform. IE11 , though you can get for 7 and 8.1. DX11.1 and DX11.2.. I have just moved my OEM System builder of Win8 pro to new MB/CPU/RAM/SSD..And it was a pain talking to those reps. Once I actually got home I was able to just use the automated service by phone. I tried Deactivating my OS but I guess that option is gone now. Still, can anyone just reinstall once using the 8.1 update, That is using the Windows Disk?? There is other things I have noticed since this fresh install that are much different from last year.
