Why did my Windows 10 upgrade require reactivation of my software?

Unfortunately, we cannot control changes that Microsoft makes with Windows updates/upgrades, and this can result in a change to the information available to our licensing to enforce the copy protection. The change in data can push the copy protection check over the threshold causing the validation to detect it is not running on the same system on which it was activated.  There is not a way for us to ensure that all cases will not prompt for a new activation, so a reactivation will be necessary in those cases. 

We have mainly seen this issue when using the Legacy Computer ID Algorithms.  If you are using Instant Protection PLUS 3 or Protection PLUS 4 SDK and the Legacy Computer ID algorithms, we suggest moving to the Enhanced Computer ID Algorithms which uses a vote system to better handle hardware/OS changes that affect copy-protection.
