Greetings I am having a problem updating one of my machines (KMS activated Pro Windows 8 VL) to Windows 8.1, any help would be appreciated. I cannot update from the store (as expected) and trying to update from any iso I have, it wants to remove everything except my documents. I would ultimately like to update this machine to 8.1 update 1 without reinstall if at all possible. Is there a standalone installer for going 8 >> 8.1? I am kinda stuck now. Thanks for any help, Paul.
