Woohoo. Posting from a Core 2 Duo with 4GB of RAM and Windows Technical Preview is snappy as hell!
The Start Menu, while it will appease the majority, is a weird step backward. I get why they're doing it, but it really doesn't make sense after using Windows 8/8.1 for a week. Whatever, though.
Install was relatively fast. I upgraded over Windows 7 and apart from one motherboard device I need to identify and get a driver for, the install has no issues. Everything is still in place. Seems solid on a quick impression. VirtualBox is hosed, however. I'll have to research that. Had been using it to run Windows XP so I could use the Aikon software to set my Gon keyboard up. If anyone has another workable suggestion on that, I'm all ears, otherwise I'll set VirtualBox up on another machine and copy my VM over.
