Hey, I am late to the game, but I am having the same problem. I installed 10, on an XP system with 2 megs. It worked fine the first couple days, now, I click the icons, get the hour glass a few seconds, then nothing happens. And I did not do anything to my system to change it.
I did a complete uninstall and reinstall, and still nothing happens. I am down and out now, not being able to make CDs, and it is killing me. I need some kind of solution to this FAST?!?
