Group Policy Client service failed the sign-in

From a cold boot: it took 4-5 minutes. Disk was active, but not taking a dump (observed disk activity light). Got message "The Group Policy Client service failed the sign-in., The universal unique identifier (UUID) type is not supported." I just sat there with that message being displayed, and no apparent disk activity.

I held the power button down, it powered down, and I restarted with no problem.

Should I be concerned?

System specs (my profile on this forum is for another desktop): Windows 10 Pro (but Belarc's Security Advisor says it is Windows 8.1 Professional (x64)(build 9600). So, I've not had the latest update nor the "anniversary" update.

Should I be concerned?

If it repeats, maybe. Some older pages that may help explain:

Thanks, Berton: I'll close this issue out for now. Read the stuff, checked the Group Policy Client Properties, they seem OK.
