My Computer Has 99 Problems, and I think I'm one of them.

For the problem " take hours for sut down "

Try this:(it works for me, i had the same problem)
If have w7, press Windows button, and write MSCONFIG, then press enter.Click on services.you should have marked the option to hide the Microsoft files.mark(Never remember now if you have to mark the files or unmark.. if you have marked, unmarked then , if you have unmarked, marked it.) all the options that you have with arent Microsoft files (all arent Microsoft files if you marked the option), and then, apply and restart your computer.

Sorry if you dont understand me..
hope i hepled you
