Registry Lost Permissions (Including Admin)

[Guest]

I have some keys in the registry and i cannot delete them as all Permissions
have been lost and i cannot delete them under administrator as this account
doesnt have any permissions either.

Any suggestions?

What do you mean all permissions have been lost? In regedit, highlight the
key, right click and choose permissions. Can they be changed from there?

Nope it cannot be changed from the Permissions security area as its blank and
noone has permissions so i cannot grant anyone permissions and i cannot
delete keys.

Has this just happened? If so, perform a System Restore to a point where the
computer was working.

Otherwise, Take ownership of the registry keys and reset the registry
permissions back to the default permissions..

I already had ownership set (i tried before) but when i was in the advanced
screen i added the permissions and it let me add admin and my username.

Thanks!
