3. once that is complete type sfc /scannow in the admin command prompt and wait for it to finish. one finished you should see a message in the admin command prompt saying that the repair is successful  then you are done.


I previously deleted  radardt.dll and radarrs.dll using everything program and when sfc /scanow was tried without the following steps above it listed the files as corrupt but couldn't repair them but after the steps above all is good.


Note: if the following keys below are deleted this will not work.
