So I just did my upgrade a while ago and started to play with it. Now I have not really used any of the preview builds
The process itself was fine, but some oddities
1 - if you open the system properties, seems to almost double open..
best way i can describe it is, it opens, then seems to close, and reopens just as it closes
seems to happen with any of the old control panel items from the WIN+X menu
2 - still cannot activate.. but that seems normal at the moment
3 - if I try to open a photo, as it defaults to photos app, it does not want to open.
my guess is cause i am not activated, easily fixed by changing it to the windows photo viewer
4 - cannot fully customize my start menu, want to get rid of the Most Used
5 - Don't have the download and install updates later even though I am on Pro
6 - don't like that for the desktop background, you cannot select a folder and browse the images like you could in win7/8
7 - Cortana not available in Canada? what the hell.. thought it was here too
Some items that I had to do but was somewhat expected
1 - install new nvidia drivers
2 - install nic drivers again. This was probably due to the fact that I had Hyper-V install in Win8.1 and did not turn it off first
