I got the upgrade from 8.1 Pro last night: 1. The OOBE experience ran twice. It rebooted half way through the first one to apply updates and then I had to do it all again. 2. It lost the product key and won't activate even though this is a genuine copy from MSDN. I guess I have to wait for a key from MSDN later today. Not end of the world but a pain point. If it isn't activated, hardly anything works now. 3. However that's all pointless as it hangs solid after 3-5 minutes reliably. That's not enough time to even roll a single windows update in so I'm shafted. This is a rock solid Lenovo X201 that has never had a single problem with any Windows release. It hasn't crashed once since I bought it new. Not impressed. Spent an hour rolling it back. I imagine, considering this was quality well tested hardware, that this is going to be nothing but hell for people. If even 1% of people have this experience, the media will blow big time and I'd hope that they do. Edit: on my Sony VPC-J1 AOI machine that fails with "Windows 10 upgrade failed" after pissing around for an hour. At least that didn't hose the machine.
