I have Windows Vista on a machine and I noticed quite a bit of hard drive was disappearing. I ran a utility to show me where it all went. I found the following directory consumes over 2GB of space: C:\ProgramData\Microsoft\Search\Data\Applications\Windows
The "Microsoft Search" service is now disabled, but I want it removed completely. I see nothing on Add/Remove Programs. Also, will I get blue screens if I delete this directory?
