I would have to revisit, but if I recall correctly, removing GDID *after* you activated your OS is *meaningless* in the sense that Microsoft servers have already logged your device. Remove it from your end all you want, that doesn't remove it from their end. We have "activation" scripts elsehwere on this forum that would be better "homes" for any GDID discussions. If I recall, if you "activate" OFFLINE then that is the ONLY way for a GDID to not exist on any server! Again, removing it from your computer is kind of pointless if you've already allowed it to be logged elsewhere. But that aside, it kind of AMAZES me how many "activation" threads there are here at MDL. I would have "assumed" them to be a violation of Forum Rules. ie, making this a borderline "warez" web site.
