I installed 8.1 preview ON TOP OF 8.0 final preview in an updated VirtualBox on a I7 based 16gb desktop (home grown). Very little survived, but it did warn me. I did have a big problem that it kept refusing to install because of some ‘feature’ missing from the VB environment, and eventually learned how to command VB to fix the problem. The one thing I couldn’t do was to get the latest extension pack installed; that’s a bit of a pain, so any suggestions greatly appreciated. Like as to how to download it and install it.
As to 8.1 itself, I was baffled that 1. the really annoying ‘curtain’ still needs to be pulled up to login, 2. that the ‘restored’ ‘start’ button only takes you back to the chimp designed and oriented childlike MUTRo screen. You’d click on the desktop, it would come up, you’d click on the ORB hoping for a menu and MUTRO would come back. Needless to say, I quickly re installed one of the Win 7 menu restore tools. Of course, MS truly did not fix what so many of us complained about, so I’ll be in no hurry to install V8.1 either.
One oddity; during the Win 8 installation, something in Virtual Box and / or Windows was absolutely pegging the cpu and ram, eventually crashing the box, even though total use of ram and cpu was limited. I’d love to figure out what happened; anyone have any idea?
