services.exe: Services and Controller app

Q: Is services.exe safe, or could it be a virus?

The genuine file is in C:\Windows\System32 and is signed by Microsoft Windows. A program can borrow a familiar name, so check where your copy runs from and who signed it with the commands in “Check it yourself”. A file with this name anywhere else, or with another signer, deserves a closer look.

The Services and Controller app, as its file description reads. Windows services are started, stopped and tracked through the service control manager, which Microsoft describes as starting at boot and keeping the database of installed services; Microsoft names services.exe among the built-in critical processes.

A built-in critical process: if it terminates, Windows stops with bug check 0xEF. To judge a busy service, look at the service itself in Task Manager's Services tab, not at services.exe.

What PC Tweaker does with it

PC Tweaker's priority rules refuse programs in the Windows folder and security software, so the app never changes this process's priority, and no control in the catalogue stops or edits it. The app changes services only through its two service controls.
