Hi Matthew,
I have checked here on my end the issue that you have brought up. The random data strings attached to system services were changed as well after rebooting. It's safe to say that this is working as intended and shadow copies of your services is a security design to prevent unauthorized applications/malware from accessing these services.
If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.
