Can anyone please tell me the reason behind the randomized alphanumeric characters at the end of service name for some Windows services?

In particular:

CDPUserSvc_xxxxx PimIndexMaintenanceSvc_xxxxx MessagingService_xxxxx OneSyncSvc_xxxxx UserDataSvc_xxxxx UnistoreSvc_xxxxx WpnUserService_xxxxx

    They are not randomized – Ramhound Jun 21 '18 at 21:24
  • I'm trying to ask the significance of the 5 alphanumeric characters that follow the underscore of each of those services - the x's are placeholders for the alphanumeric characters. – Pokopokopoki Jun 22 '18 at 00:41
  • Such as CDPUserSvc_3951d. – Pokopokopoki Jun 22 '18 at 00:42
  • The numbers are different for every different Windows virtual machine I create. On another VM, I am seeing the same service with a different alphanumeric sequence at end of it - CDPUserSvc_33c6b. The other services I mentioned - PimIndexMaintenanceSvc, MessagingService, OneSyncSvc, UserDataSvc, UnistoreSvc, and WpnUserService - will all end with the same alphanumeric sequence. I am just wanting to understand the significance of this alphanumeric sequence. – Pokopokopoki Jun 22 '18 at 00:48
  • The random codes are for security reasons; see the answer of this post: https://superuser.com/questions/1182820/malware-or-strange-windows-services-behaviour – Mu-Tsun Tsai Sep 17 '19 at 06:16
