Often you need to make changes to the user’s Registry to solve issues.
But that is easier said then done, even if you are an administrator 
(giving the conditions that you had not set all prerequisites already using Group Policy settngs)
So here we go :
– first get a version of MS Sys Internals – PStools In my case the latest version 2.0, did not work ! So I went back to version 1.98.0.0
Once you start the PSEXEX cmd make sure you use the –h parameter to run with elevated permissions.
-h If the target system is Vista or higher, has the process run with the account’s elevated token, if available.
Example :
PsExec.exe -h \\PC_NAME cmd
Once started you can see in the CMD prompt windows that you connected correctly.
Now run the following cmd :
netsh firewall set service REMOTEADMIN ENABLE SUBNET
Next start on your machine AND the remote PC the following cmd :
net start RemoteRegistry
Check on both sides if it is started.
Now you are ready to connect to the remote registry using the GUI
Enjoy !
