laptop is running windows 7 64 bit and i just used the latest tweaking program
went through all the steps ... all in safe mode with networking ... repeating some steps a few times
yet when i finally got to the final stage (repair)
it couldn't do it ... saying something's blocking it ... to bring it to this forum for help
prior to starting this attempt ... I've had trouble with "not having privilege, not permitted" or something like that ... that was maddening since I am sole user with administration rights etc ...
