Enable Multiple Users

1. First Open REGEDIT using command line
2. Look for this entry: 

   HKLM\System\CurrentControlSet\Control\Terminal Server\:

3. Next, look for the following key: fDenyTSConnections
4. Change DWORD from 1 to 0. This enables RDP on your computer
5. Now, look for this key: fSingleSessionPerUser
6. Change DWORD from 1 to 0. This allows multiple users to use remote desktop at once even if there is a console user in session. 

Done!
