How do I allow multiple users to use Remote Desktop?


Normally, Windows 8.1 only supports a single remote connection. I wonder how to enable multiple users Remote Desktop in Windows 8.1? We’d like to do this just like we have on Windows Server 2003.”

- Question from SeverForum

Users running Windows 8.1 Pro and Enterprise editions (the Home edition is incompatible) can set up the Remote Desktop Connections via RDP. However, in Windows 8.1, only one simultaneous incoming RDP connection is supported. When you attempt to log into two or more accounts on the same Windows 8.1 machine at the same time, you will receive the following notification:

Confirm Dual Connections

If in some cases you may want the ability to login concurrently, what can you do? Actually, using a special patch to replace the termsrv.dll system file can alter the RDP setting to literally allow unlimited concurrent user access through Remote Desktop Connection. Let’s take a look at how to enable Windows 8.1 Remote Desktop multiple users.

How to enable Windows 8.1 Remote Desktop multiple users

Here in this part, we’ll introduce how to connect multiple users to Remote Desktop Windows 8.1 using a special patch.

Using this patch breaks the licensing agreement and the terms of use for Microsoft products. Perform all the operations described below at your own risk.
You are advised to only use this method in a test environment. If you want to achieve concurrent connections in a production environment, please purchase RDS CAL.

Step 1. Download the zipped patch file that includes both the original and patched versions of the termsrv.dll file for Windows 8.1.

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:

copy c:\Windows\System32\termsrv.dll termsrv.dll_old

Backup Original Termsrv_dll

Step 4. Change the values of the following keys in HKLM > System > CurrentControlSet > Control > Terminal Server:

  • fDenyTSConnections (DWORD) — 0
  • fSingleSessionPerUser (DWORD) — 0

Multiple Users Registry

You can also do it quickly by entering the following two command lines in the Command Prompt:

  • REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server” /v fDenyTSConnections /t REG_DWORD /d 0 /f
  • REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server” /v fSingleSessionPerUser /t REG_DWORD /d 0 /f

Step 5. Then go to C:\Windows\System32, find the file termsrv.dll, and right-click to open its Properties.

Step 6. By default, the owner of this file is TrustedInstaller and even the administrator doesn’t have any right to replace it. You need to give full control of this file to the administrator. Click Change.

Give Full Control to Administrator

Step 7. 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.

Step 8. Copy termsrv.dll from the archive downloaded in Step 1 for your Windows 8.1 to %SystemRoot%\System32\ (with replacement).
