Windows – How to change the priority of a Windows service process

priorityprocesssp3windows xpwindows-search

I would like to run the Windows Desktop Search indexer at below normal priority. When I try to set this via task manager, I get 'Access is denied'.

Is there a way to remove whatever restrictions are protecting this process? Or ideally, configure it to have the lower priority on startup?

XPSP3 btw.

If you are logged in as Administrator, give Process Explorer a go. I've changed priority of processes before that Task Manager was unable to change.

If you don't really need it you can turn it off altogether (Go to the properties of your C:\ drive, and uncheck "Allow indexing service to index this drive for fast file searching" then hit apply). Everything from void tools is much faster for finding files.

Windows – How to Allow Non-Administrators to Use shutdown.exe

The simplest solution would be to configure said scheduled task to run under an Administrator account. You do not need to use the same account as the usually-logged-on user – simply provide different credentials when creating the task.

If you do not want "Administrator" to have a password, you could just create a dedicated account just for the scheduled task. (A limited User account will work as well, if you apply the fix below.)

The shutdown.exe program needs SeRemoteShutdownPrivilege to run, instead of the usual SeShutdownPrivilege – my guess is that it uses the same RPC for shutting down both local and remote machines. (This would explain the need for a password, too – by default, only console logins are exempt, which obviously does not include RPC.)

You can grant SeRemoteShutdownPrivilege through secpol.msc → Local Policies → User Rights Assignment, by editing the "Force shutdown from remote system" entry.

You can create a dedicated account for the task and add it here (best choice).
For interactive command-line usage by any user, you can add INTERACTIVE.
For scheduled tasks by any user, add BATCH.
