I’m up to my neck in 8.1 upgrade hell right now.. installed the update a couple of hours ago.. now my soundcard isn’t working along with half a dozen other bits of hardware. It changed my keyboard to US layout and tried to force me to log in with my Microsoft account instead of the local one. (hint: type nonsense in the username field and it’ll assume you forgot your details and allow you to login using your local account!)
Oh and in the course of tarting up the start menu it managed to lose or reorganize all my custom shortcuts.. (google oblytile if you are interested!)
Overall not best pleased as I’m now staring down the barrel of a clean reinstall of the whole OS in order to clean up the mess it’s left.
Oh and it also created a windows.old folder which it will not let me get rid of…
Grrrr…
Roll on OSX Mavericks next week..!! 🙄
Note: YMMV
