REGSVC.exe
(Microsoft)
Microsofts Remote Registry Service. This service runs on Windows 2000 Server and Advance Server. Whenever you install Microsoft software such as SQL on Windows 2000 Server, and your setup program needs to write keys to the Registry, it interacts with the Remote Registry Service (REGSVC.EXE) and the Remote Registry Service does the actual writing of the registry keys. This background service is also required if you intend to edit the registry from a remote computer using Windows 2000s Remote Administration facilities.
Recommendation :
While it is not always required, the Remote Registry Service will eventually be used at some stage in the life of most Windows 2000 Servers/Advanced Servers. This process should therefore be left alone.
