There's no consistency or thought put into the interface. It's ridiculously hard or obscure to do simple things (like working out how to install it without a Microsoft account).
I'll give you that one, but it is easy enough once you know how. And they do it directly because that want people to link their devices so that your Metro apps follow you etc
It's put a water mark on my desktop because secure boot is turned off.
Never seen that, but why do you need to disable secure boot anyway?
The metro apps that default to opening things are completely wank and either don't work, or they're so hard to use you just /think/ they don't . Like the default image viewer: you have to hold down control and use the mouse wheel to zoom in/out. Why? mouse wheel on its own does nothing, so it's not like it's a modifier to extend available functions. And setting an image as a desktop backgroun? You might think you should open it up and choose 'set as desktop background'. But oh no, you can only set it as a /lock screen/ if you fucking open it. If you want to set it as a desktop background you have to right click it in explorer and choose 'set as desktop background' there. But you can't set it as lock screen that way, that'd be too simple.
I forgot to say - totally forget about Metro and continue to enjoy your new Operating System. Win 8 has loads of little touches that make it nicer than Windows 7 in its normal desktop mode. Literally, just forget everything about Metro.
And this is the second 8.1 laptop that I've had serious issues with Wifi on, and a quick google suggests I'm not alone. I don't know what they've done to the way it's handled, but on tracy's laptop it randomly drops out, or reduces the speed to a crawl: a torrent can go for over 1MB/s to 100k/s, turn wifi off and on again and boom - straight back to 1MB/s for about 5 minutes or so, then it slows back down until you turn wifi off... ect.
Not seen this, either, sorry.
