How do I allow multiple Remote Desktop connections Windows 7?

“How do I allow multiple, simultaneous user logins (RDP) to my Windows 7 server?”

-Question from Microsoft Forum

At beginning of the post, we are sorry to tell you that Windows Server OS, for example, Windows Server 2012 R2 allows 2 Remote Desktop connections for each user, but Windows OS, like Windows 7 only allows one simultaneous incoming RDP connection. When initiating the second RDP connection, you will see the following message popping up:

Confirm Dual Connections

But this doesn’t mean it is totally impossible to allow multi user login Remote Desktop Windows 7. Actually, you can have Remote Desktop Connection multiple users at the same time by replacing the Termsrv.dll file and performing the Registry modification.

Warning: Before starting this process, it is important to warn you that using this workaround is a violation of the Microsoft License Agreement. Therefore, you’re advised to perform this workaround only in a test environment.
