My experiences so far:
It has a useless “settings” window where you can change fuckall settings, it’s very pretty, but to change my ip-settings I still had to find the win2000 style “control panel”. I’m sure the rest of the OS is cutting edge but this looks suspiciously as if it’s still same old windows, tarted up a bit differently than its predecessor.
Since I use Dropbox (LAN sync!) I have no use for skydrive/ onedrive it is an absolute pain to remove, stopping the client was checking one checkbox but removing the “onedrive” link from explorer (where I tend to spend quite some time so I don’t need useless clutter) was a very poorly documented aund tedious trek though the register.
Removing all the weather/news/stock ticker/Xbox crap from start menu was relatively painless.
The photos app is quite useful to browse photos and works relatively fast, in fact the whole UI feels fast.
Finally! Mounting ISO 's natively in windows (something Linux has done for as long as can remember) bye bye daemon tools.
Native AV.
The gui really is a thin veneer of new over an NT structure.
Bing is still useless. I’m staying away from corthingy/clippy 1.09.@ 1, switched that off.
All the stuff I’ve installed works flawlessly, office 2007, windirstat, iTunes, vlc, chrome, calibre, various VPN clients, ccleaner, handbrake
Multiple desktops! Finally.
For some reason the installer thought I wanted a Dutch interface (granted I’m Dutch and live in holland) however the installation of a different language was completely painless.
So: nothing earth shattering but a useful incremental upgrade from win 7 and a return to sanity from win 8.
