Clean out the prefetch folder :


                                                                    Windows XP uses a system called 'prefetch' to organize and preload some of the data necessary for commonly used applications and files. A folder called prefetch is used to store the information the operating system needs to carry out this operation.
After several months of use, the prefetch folder may become quite overloaded with older references to software and files that may no longer be in use.It's a good idea to manually empty the older files out of the prefetch folder every few months or so.
To do this: Navigate to 'c:\windows\prefetch' and delete all .
PF files that are older than a week or two.
