By default, Windows 7 is designed to allow only one active Remote Desktop Protocol (RDP) session at a time. If a user logs in remotely while the host computer is logged in locally, the local session is locked and the screen goes black. Alternatively, if a second user attempts to RDP into a machine already being used remotely, the first user is disconnected.
The Universal Termsrv Patch modifies the termsrv.dll file (the library responsible for Terminal Services) to remove this "single session" limitation. This allows multiple concurrent RDP sessions, meaning two or more users can be logged into the same Windows 7 machine simultaneously, each with their own isolated desktop environment.
In many older versions of Windows 7 64-bit termsrv.dll, the key bytes to find and replace are:
A more modern "Universal" patch tool might do a wildcard search for a pattern like:
8B 81 38 06 00 00 83 F8 01 0F 84 ?? ?? ?? ??
And change the F8 01 (compare to 1) to F8 02 (compare to 2) or bypass the conditional jump entirely.
The "universal" aspect means the tool looks for the logic structure (the conditional jump for single session) rather than an exact byte-for-byte match. This is why it survives some Windows Updates.
Every time Microsoft releases a security update for termsrv.dll (e.g., monthly rollups for Windows 7 ESU - Extended Security Updates), the patched DLL is overwritten. Your system will revert to single-session mode without warning. You must re-patch after every update.
The open-source RDP Wrapper Library achieves similar results on modern Windows clients without modifying system files. However, it’s still a hack.
Go to Control Panel > System and Security > System > Remote Settings and select "Allow connections from computers running any version of Remote Desktop".
