>> "Why is it that the original Windows 10 install and these major Windows 10 updates keep erasing the lime activation data and making the software think it's a new computer?"
You need to email me product keys showing this behavior. My guess, 1 of 2 things is happening:
1. The customer is using your app on a different computer and lying about it.
Or...
2. The customer isn't upgrading from Windows 10 to Windows 10 Anniversary, but rather upgrading from old-Windows (XP, Vista, 7, 8, 8.1) to Windows 10 Anniversary AND they have multiple network cards. The solution is to use TA 3.4.7 in the short term. The long term solution is to use TA 4.0 (when it's out -- soon).
I was guessing about TA_USER / TA_SYSTEM. Much more information is needed to make any sort of accurate statement. If the user is "becoming deactivated" it's likely not because those files are being deleted. Especially if they cannot re-activated with the same product key.
Upgrading between Windows 10 builds and "losing the activation" is not reproducible by us. We've tried. We have many computers some running on the "Release" Windows 10 build, some running on the "Insider" build (meaning "large system upgrades" come bi-weekly). We've never been able to reproduce this.
Please give me more information so we can look into this.
