However, something I have asked is still missing.  I will post it again:

So the test would be:

• We need to work on only on PC (you have another in your activation logs).
• When you are prompted, and before you activate, go here:
  C:\ProgramData\Stardock\Start10
• If there are files there, copy those files somewhere (desktop is fine).
• Go here:
  C:\Users\YourWindowsAccountName\AppData\Local\Stardock\Start10
  Please note that YourWindowsAccountName is where you would use your Windows account name.
• Copy the sasLog.txt to where you put the other files (if they exist).  Zip them naming the zip SAS_Old
• Activate again
• Do the steps above again, getting the activation files and sasLog.txt, zip them as SAS_New
• Create a ticket here:
  https://esupport.stardock.com/index.php?/Tickets/Submit
• Send me both zip files and note the link to this thread in the ticket.

Edit Note: We suspect the files in C:\ProgramData\Stardock\Start10\ are getting deleted after a reboot.  Possibly an anti-virus program is deleting them. Any insight on help confirming that the files are getting deleted and what might possibly be deleting them will be appreciated.

Further to my note:

My Laptop has 2 Ubuntu installs and 2 Win 10 installs. While the computer name is the same for both, the partition sizes are 98 vs 99 GB or some such (i/e/ slightly different).
As it has EFI, both Windows installs boot from the same EFI.

Now, if I boot Win 10 Office and then boot Ubuntu and then boot Win 10 Virtual, I am OK - but if I boot from 1 Windows into the other (whether reboot but proper off/on restart), I get prompted for activation.


Hope this helps,

Hello,

I have forwarded your problem to Stardock Support team for their assistance. Please keep an eye on this thread for any updates. We appreciate your feedback and patience.

Note : It is best if you can post a video that show the problem so we might understand your problem clearly.

Thanks

If the PC / VM / Install looks significantly different to us (OS and hardware) when it phones home, you will get prompted - that is not avoidable.

Understood and expected, Sean.

However, the only differences are

* size of HD partition (ca. 1 GB or so - 97.7 vs 98.6 GB if memory serves)

* programs installed  - one is for Office or is for VMs mainly.

Processor, Ram, Graphics etc - all the same as it is two installs in two partitions

To be clear - both installs are onto the same bare metal - one install is just for hosting VMs.

Also, booting Linux between the two Windows boots alleviates the problem.

The fact remains that something looks different to us.  I cannot talk about the 'secret sauce' - all that we look at for determining that - for obvious reasons (if known, someone clever could work around them).

That said, you can alleviate the problem to the point you would likely not ever see the activation prompt.

You could create a batch file, to run manually, or as part of your startup, to activation silently:

If you made it part of your startup - you would never see the prompt, or if you did, could dismiss it knowing that it was activated - just after the prompt appeared. 

What would be problematic with that is if every time you used another instance, it looked different to us - meaning, each time you use one, it looks brand new.  If that is the case, you would eventually run into max activations (5 currently).  That too can be mitigated by silently deactivating on log off (also documented in that link).  Even if the instance failed to log off properly (thus not being able to deactivate), your account portal will allow you to do it manually:

Hope that helps.
