I did the same stupid thing as seancho and denied the access to all users.
After that I managed to install Avira Free without problems.
But when I tried to change back the registry changes I received a warning: Error Opening Key. ProductOptions cannot be opened. An error is preventing this key from being opened. Details: Access is denied.
Then I made another stupid thing, I restarted the comp, erasing the “last known good configuration”, because it loaded win 2008 just fine.
So, now I have a “normal” running system, but I cannot change the registry tweak back to the original state.
Should I be worried? Is there any way to recover the registry now?
EDIT: I made all the registry modifications as Admin.
