Some of the Windows Services shown in Services.msc have an underscore in their name. Two examples are CDPUsrSvc_277cef and "Contact Data_277cef". This seems very suspicious to me. I'm pretty sure that the original name of those services did not contain the _277cef appended to the end. There are a couple more services that are the same way. Why do some of the services have _222cef added to their name? What is doing that? Yes, I have anti-virus software installed and I am very careful about malware and going to bad Internet sites.

I think the last line of the reply in thread I linked is appropriate "Properly could do with some finishing touches on the service..." so basically sloppy (imho) programming. The suffix being the same note sure but different on different PCs so programmatically got on the system it looks like to me.

Surprised that there is no correct answer to this. These are per-user services in Windows 10 (or server if you are using desktop experience): /en-us/windows/application-management/per-user-services-in-windows

Present on Windows 10 1607 system been noticed and the above post discusses the CDPUsersvc. The numbers do change between systems.
Looking at Contact Data_5562e on mine the path to executable is the same svchost.exe -k UnistackSvcGroup so the same as CPUsersvc to me. Double click the properties and then on the General tab the Path to executable will tell what they run and give you an idea of what they do or a starting place.

Thanks for the info. I am more curious why approximately five services all have _277cef appended to their name and what is doing that than what the individual services actually does. I can probably figure out what the services do but why are some renamed with an identical suffix?

Thanks Martin. You actually provided the answer to this and I thank you for that.
