Microsoft will fix it for you
Click, click, fixed
Microsoft has opened up a repair shop online to identify and fix common software problems in Windows PCs.
Currently in beta, Fix It Center  consists of a client that you download onto your PC and an online option that enables you to manage multiple computers from a single location on the Internet.
A library of troubleshooters can either fix issues automatically, or you can choose which issues you want the software to resolve.
If you still need help, reports from troubleshooters are included in support incident requests.
Fix it Center can be installed on the following Windows flavours:
• Windows XP SP3
• Windows XP Pro (64-bit) SP2
• Windows Vista • Windows 7
• Windows Server 2003 SP2
• Windows Server 2008
• Windows Server 2008 R2
