[Fixed] RDP Wrapper Not Working After Windows Update
Is your RDP Wrapper not supported after the latest Windows 10/11 update? Learn 3 proven methods to fix termsrv.dll issues and get remote desktop working again.

Why is RDP Wrapper not working after a Windows update?
Is your RDP Wrapper showing "Listener State: Not supported" after a recent Windows update? You are not alone. The most common cause is a version mismatch. When Windows updates, it often installs a new version of the Remote Desktop Services library (termsrv.dll). Since RDP Wrapper relies on specific offsets within this file, the "Not Supported" error occurs because the current rdpwrap.ini file doesn't have the data for your new Windows build (e.g., Build 21301).
In this comprehensive guide, we provide three tested methods to restore multiple remote desktop sessions on Windows 10 and 11, ranging from manual configuration fixes to a more stable, legal RDP Wrapper alternative.
3 methods to fix RDP Wrapper not working after Windows update
This section walks you through the most reliable solutions, with clear, step-by-step instructions to help you get everything working again quickly. Before you begin, be sure to review the Security & Compliance Note. If you’d rather avoid potential risks, consider using a safer alternative to RDP Wrapper instead.
Before proceeding, please understand that RDP Wrapper functions by modifying the termsrv.dll system file. This may:
- Violate Microsoft’s Licensing Terms: Modifying system binaries can be seen as a breach of the EULA.
- Trigger Security Risks: Ensure you only download configuration files from trusted, open-source repositories.
- System Instability: Improper modifications can cause the Remote Desktop service to crash. Always create a system restore point before starting.
Method 1. Manually update rdpwrap.ini & replace termsrv.dll
This is the most effective technical fix for the "RDP Wrapper listener state: Not supported" error. By updating the configuration file, you tell the wrapper how to interact with the new system library.
Step 1. Navigate to C:\Windows\System32\termsrv.dll. Right-click and select Properties.
Step 2. 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.
Step 3. 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 4. Run Command Prompt as Administrator. Stop the termservice by executing the command "net stop termservice".
Step 5. Back up and rename the current termsrv.dll file using the following command:
copy c:\Windows\System32\termsrv.dll termsrv.dll_old
Step 5. Additionally, copy the termsrv.dll file from the termsrv.zip archive into the System32 directory.
Step 6. Install RDPWrap 1.6.2.
Step 7. Add the codes from the following link to the C:\Program Files\RDP Wrapper\rdpwrap.ini file.
https://raw.githubusercontent.com/sebaxakerhtc/rdpwrap.ini/master/rdpwrap.ini
Step 8. Once again, run CMD as Administrator.
Step 9. Start the termservice using the command "net start termservice".
Step 10. Restart your computer and check RDP Wrapper not supported is fully supported right now.
Method 2. Enable multiple sessions via Group Policy Editor
For users of the Professional and Enterprise editions of Windows 10, resolving the identified issue can be achieved by adjusting a specific parameter in the Group Policy Editor.
Step 1. Click the Search button located next to the start menu, then type in "gpedit.msc."
Step 2. Navigate to the following path: Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.
Step 3. On the right pane, locate and double-click "Limit Number of Connections."
Step 4. You have the option to set it to "Enabled" and specify the desired connection limit.
Step 5. In the Connections section on the right pane, find and double-click "Restrict Remote Desktop Services users to a single Remote Desktop Services session."
Step 6. Set it to "Disabled" to deactivate user restrictions.
Step 7. Reboot your computer to apply the changes effectively.
Method 3. Use a stable alternative (AnyViewer)
Manually patching Windows system files is risky and often breaks during every monthly update. If you want a permanent, legal, and hassle-free solution, switching to professional remote desktop software like AnyViewer is highly recommended.
