Part 1. Perform the Registry modification
Step 1. To launch the Registry Editor in Windows 7, press Win + R, type in “regedit”and then press Enter.

Step 2. Press Win + R, and then type in “services.msc” to open the Services management console. Find Remote Desktop Services in the list and right-click it to stop it.
Step 3. Run Command Prompt as administrator, back up the original termsrv.dll using the following command in case something goes wrong:

Step 6. Go to the Security tab and click Edit. Find the local administrators group and give it full control over this file and save the changes.
