I've kinda posted this on every Windows 8 thread on here now, but most of the confusion comes from trying to use the tablet interface, just use desktop mode exactly like you did in Windows 7, the tiles etc are for touchscreen, absolutely no need to use it on a normal desktop/laptop. I've only been using it for a couple of months, but I've not had problems with any programs running on it, prefer the interface to 7 now i'm used to it and while I still agree MS made some mistakes (mainly not defaulting desktops into desktop mode), I think it really does get a lot of unfair negativity.
Pin the programs you use most to the taskbar (right click their icon at the bottom while theyre running and select pin), then you can launch them from there each time. I'd suggest your browser, your mail, a windows folder and anything else you use regularly.
For anything else, simply hit the windows key and start typing the name and itll find it for you, hit enter or click it and it runs, faster than a start menu. (also works in windows 7 which is why MS don't think anyone uses the start menu)
Make sure if you open any documents/media files, you right click, choose open with and choose the desktop version as default.
For the old right hand side of the start menu, hit Windows Key+X and it brings up an improved start menu minus the programs.
Windows key+D, or moving mouse to top left corner of screen switches you back between metro and desktop modes.
Windows Key+E launches explorer (as it did in win7)
I don't mean to offend, but unless you have a touchscreen, don't watch the video above, you (and all the people complaining its a tablet OS

) have no need to be going near the silly tiles, stay in desktop mode and use it like a slightly different windows 7. Honestly give it a week, stay away from Metro and there's a decent chance you'll like it. If you're finding anything difficult I can *probably*, help find the easy way of doing it if you ask
