I have windows vista and have been experiencing problems lately. I no longer can use nero to burn cd's... i keep getting an error saying that windows indexer isn't working right now, and lastly windows media player doesn't work either. I am not sure what the source of the problem could be... But i have a lot of programs but most of them are full version and aren't free. Whats the best solution to this? Do i have to wipe my pc clean and start over again? its really annoying that i can't use windows media player anymore

and yes, my computer is up to date...
