gonna turn it off
Microsoft Locator
needed system file
I terminate this process when playing online games. Doesn't seem to have any adverse effects on system operation when it's turned off.
Locator.exe is the remote procedure call locator service and is essential for the smooth running of Microsoft Windows. This process maintains a database of publicly declared procedures. This program is important for the stable and secure running of your computer and should not be terminated.
Disabling this service might cause your printer driver installations (and possibly other drivers aswell) to FAIL with an RPC error. Considering the service's minor memory requirements (2,5 megs), leave it running and save yourself the trouble later.
if in the right place, then ok.

Agree with Pit, everything runs just fine without it.
It redirects your browser .Beware. Very Dangerous.
I agree that this is a file / service for the remote procesure call built into windows, however I noticed the proccess only after installing clearwire. I removed the software but it still stays enabled. if this process is terminated, my computer runs just fine but with network utilization dropping from 15% to 3% without any network dependant apps running. This tells me it is doing something that pulls or sends information over the network. Spyware/Malware have also been known to use the same name so be cautious and research before removing but removing/deleting could be an option if suspected.

I turn if off on XP Home Ed. - No problems noted.
locator.exe is not needed in windows 7 or later versions!!!Most of you Folks seem to think this is the RPCSS service,not the plain RPC which is only present for application compatibility in Visa and later versions of windows!!! "In Windows 2003 and earlier versions of Windows the remote procedure call(RPC)Locator service manages the name service data base.In Windows Vista and later versions,this services does not provide any function and is only present for application compatibility." Check services in Vista and 7,8 etc

This service could be used to sniff other network locations to retrieve information about different machines on your network. It is harmless in and of itself, but can be used for data collection or possibly alter configuration values on your machine. This is taken right out of the Windows 7 Service description: "In Windows 2003 and earlier versions of Windows, the Remote Procedure Call (RPC) Locator service manages the RPC name service database. In Windows Vista and later versions of Windows, this service does not provide any functionality and is present for application compatibility."

Best practices for resolving Locator issues

A clean and tidy computer is the key requirement for avoiding problems with Locator. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
