Although your startup procedure is more complex, your computer must also check the registry before closing. This can again take time. You should fix PC registry problems in this area to avoid long shutdown problems. One way is to alter Alter your Paging File Settings-- The paging file (Pagefile.sys) is a hidden file on your computer's hard disk that Windows XP uses as if it were random access memory (RAM). Therefore this file can be huge. On shutdown it must be cleared. Here is how:

1. Find the folder: HKEY_LOCAL_MACHINE>System>CurrentControlSet>ControlSession> ManagerMemory
2. At this point you will see a list of files, Double click on Clear Page File At Shutdown
3. Change the value of the paging file to "0"
