Thank you MagicAndre1981! But you are wrong because services can slow down the PC. Source: http://support.microsoft.com/kb/959062 "There are several tasks you can perform when using Vista to improve slow performance. Vista contains built-in-features that allow you to manage potential slow performance issues. These include: Deleting programs you never use Limiting how many programs load at startup Running fewer programs at the same time Turning off visual effects Restarting regularly Checking for viruses and spyware Checking your computer’s speed Disabling services you don’t need" Any questions?
