Curious, what causes a change in the PCID??
Reason I'm asking is I used the machine, for a couple hours at least, last night and no problems.
I go to use it today, and Windows 10 (complete junk in my opinion) had to update. So I updated, restarted, continued with what I was working on. Mid cutting the machine just stops. I figured typical Mach4 B---S--t, so I restarted, and it did it again. This time I saw the message saying demo expired (not verbatim).
Didn't understand what was going on at this point, but sure enough, my PCID had changed. Only thing that could've done it was the updates. The pc is off all day until I turn the machine on.
So again, what constitutes a change in PCID??

Replacing a hard disk, or upgrading the OS version.

No one knows what Microsoft does with updates in Windows10. That is
why we tell people to only use Windows10-Pro and turn off the updates.

If you feel compelled to do the updates, make a restore point so you
can get back in case the update breaks something.

So all I did was activate a new license, then deactivate the old. Does the deactivated still count towards the 5??
If so, these updates can go through 5 licenses easily!

Five is the number of Mach4 licenses that can be active at one time.
