STEP 3
Go to C:windowssystem32dllcache;
rename the termsrv.dll file to termsrv.original or another name you like;
copy into the folder this unrestricted old version of termsrv.dll;
go to C:windowssystem32 (the upper folder of the current one);
do the same operation: rename termserv.dll also here, and put another copy of the file I linked above.
