Unlocking Multi-User RDP: The Universal TermSrv Patch for Windows 7 (64-bit)
By default, non-server versions of Windows like Windows 7 (Home Premium, Professional, and Ultimate) are restricted to a single active user session. If you try to log in remotely via Remote Desktop (RDP) while someone else is using the computer locally, the existing user is kicked off. The Universal TermSrv Patch is a popular community-developed tool designed to bypass this limitation, allowing multiple users to connect to a single Windows 7 machine simultaneously. What is the Universal TermSrv Patch?
The patch targets a specific system file called termsrv.dll located in the C:\Windows\System32 folder. This file controls the Remote Desktop Protocol (RDP) services. On desktop versions of Windows, Microsoft includes code that limits active sessions to one. The Universal TermSrv Patch, created by a developer known as DeepXW, modifies the hex code within this DLL to remove that restriction. Key Features

When Microsoft released Windows 7 (and later Windows Vista and 8), they drew a very hard line between client operating systems (Windows 7 Home, Professional, Ultimate, Enterprise) and server operating systems (Windows Server 2008 R2). One of the most significant technical limitations built into the client OS is the Remote Desktop Protocol (RDP) single-user restriction. TeamViewer – Supports concurrent remote sessions with a
By default, Windows 7 64-bit is configured to allow only one active interactive user session at a time. If you are physically sitting at the computer (Console session) and someone tries to connect via RDP, you are either locked out, or the remote user takes over your session. Similarly, if a remote user is logged in, you cannot physically log in at the console without booting them off.
For IT professionals, small business owners, and power users running legacy hardware or software on Windows 7, this limitation is a massive bottleneck. Enter the "Universal Termsrv Patch" — a modified version of the termsrv.dll file that bypasses this restriction, allowing concurrent multiple RDP sessions.
