Basically what they do is restoring the dates of the key to the time it was first created so that it can be reused again. The trick certainly work but the problem is when the key is activated more than once automatically it will be blocked as Kaspersky lab blacklist database have detected it during the first activation. New original key on the other hand can be reused/re-activated multiple times as long as it is not yet expire.
