I could have sworn there was a thread for Win7, but this is the only one I can find now. In any case, here's what works for 6.1.7601.25757 (x86), which is assumed to be the final release: FIND REPLACE 00 3B 86 20 03 00 00 0F 84 35 19 01 00 B8 00 01 00 00 90 89 86 20 03 00 85 E0 FE FF FF 43 85 E0 FE FF FF 90 74 2F 68 E8 7A E9 2C 00 00 00
I prefer memory patching instead of modifying system files, so I made this tiny Avrf-based hook which will patch the termsrv.dll in memory so no files are changed. Supported version is the currently latest (6.1.7601.25757) 2021-11 , both x86/x64 versions. There are also some .reg files included to easily change the relevant RDP config options without having to waddle through the group policy editor. Readme: Spoiler: README.TXT Code: _________________ | | | RDPConfig7 v1.0 | |_________________| CONFIGURATION OPTIONS ===================== Concurrent-Connections ---------------------- Default: Allow Requirements: WinServer2008R2 / TermSrvAvrf Controls whether multiple connections are allowed. - If not allowed, any logged in user will be logged off when another one logs in. Multiple-Sessions-Per-User -------------------------- Default: Deny Requirements: WinServer2008R2 / TermSrvAvrf Controls whether multiple sessions are allowed for a single local user account - If allowed, multiple users can start sessions under the same user account/profile - If not allowed, logins to the same account will be directed to the same session - Allowing this option has no effect unless "Concurrent Connections" is also allowed - Denying this option will not deny multiple connections under different users Enable/Disable-Server --------------------- Default: Disabled (Win7) / Enabled (WinServer2008R2) Requirements: WinServer2008R2 / Win7Professional / Win7Ultimate / Win7Enterprise / TermSrvAvrf - Self-explanatory, enables or disables the RDP server - Enable-Server also sets some sensible defaults + Enables RDP 8.0 protocol + Sets password authentication + Sets secure RPC communication to required + Sets connection mode to TCP only for stability TERMSRVAVRF =========== TermSrvAvrf removes arbitrary RDP restrictions from all Windows 7 and Windows Server 2008 R2 editions. Install/Uninstall by clicking the .cmd file in TermSrvAvrf folder. The install script will check whether you are on a supported version before proceeding. TermSrvAvrf installs as a Application Verifier for termsrv.dll and patches the functions in-memory. No files are altered, so if you choose to uninstall it, nothing will be left behind. It uses 8KB of RAM and applies the patch once on load so there is no performance impact. TermSrvAvrf automatically disables itself on unsupported versions so it is always safe to use, as it will never break anything if future updates happen.
