Enable Curtain Mode in Chrome Remote Desktop [How to]

If you want to have a private remote session, then you might be interested in Chrome Remote Desktop Curtain Mode. This feature isn’t enabled by default, but you can access it with a few tweaks.

How can I enable Chrome Remote Desktop Curtain Mode?

1. Modify your registry

1. Press the Windows key + R and type regedit.
   
2. Once Registry Editor opens, navigate to HKEY_LOCAL_MACHINE\Software\Policies\Google\Chrome\
3. Right-click the right pane and choose New and then DWORD (32-bit value).
   
4. Enter RemoteAccessHostRequireCurtain as the name of the new DWORD.
5. Lastly, double-click it and set its value to data to 1.
6. Next, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server
    
   
7. Double-click fDenyTSConnections and set it to 0.
8. After that navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
   
   
9. Set UserAuthentication to 0
10. For Windows 10, inside of the RDP-Tcp key, locate the SecurityLayer key and set it to 1.
    

Keep in mind that Google and Chrome keys in Step 2 might not be available, so you’ll have to create them manually.

2. Use Command Prompt

1. Press Windows key + S, type cmd, and choose Run as administrator.
   
2. Paste the following code and run it: reg add HKLM\Software\Policies\Google\Chrome /v RemoteAccessHostRequireCurtain /d 1 /t REG_DWORD /f && reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /d 0 /t REG_DWORD /f && reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v SecurityLayer /d 1 /t REG_DWORD /f && reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v UserAuthentication /d 0 /t REG_DWORD /f && net stop chromoting && net start chromoting
3. Close Command Prompt.

This method will achieve the same results as the previous solution but with less user input.
