I love windows 7 beta and have been using it since it was available as official beta. I don't really remember if I activated or not during the installation but now I'm getting messages that my windows is not genuine. When I go to computer properties I get "Windows activation - Status not available, Product ID: Not available". I have a valid key and the beta was downloaded from microsoft. When I restart I do not get the message again for a while.I've searched online but I cannot get the link to change the product key and also I get an 0xC0020012 (interface not known) error when I try to activate via slui.exe. I have already tried disabling the firewall, running slui.exe as admin with no success.For the moment I have to restart everytime windows says its not genuine...Help me please!Thanks in advance,

Hi,Thank you for your answer, I tried it with no success... it did get a little further though, at least I could see the activation process but it failed again later after that. I finally decided to reinstall Win7.I hope your answer might help some having a similar problem.Bye,
