Windows XP: Disable Indexing Service
Contributed by Rob Rogers 
Tagged: Windows networking As its name indicates, the Indexing Service indexes contents and properties of files on local and remote computers and provides rapid access to files through flexible querying language. This service is a major resource hog and should be disabled. To disable the service, open up Notepad and copy the following:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cisvc]
"Start"=dword:00000004
Save and name the file something like XP_Disable_IndexingService.reg. Run the reg file you just created and reboot. You should notice an increase in system performance.
