Basically allowing multiple users logged into Windows at the same time boils down to modifying 12 dwords<\/a> (32-bit words) or 48 bytes in termsrv.dll and the content and location (byte offset) varies depending on which version it is. <\/p>\n\n\n\n

The rest is just fighting with file lock behavior, Windows self-repair, updates, anti-virus and things that tries to ‘correct’ the modified file so the changes stick. These are hell of hard and tedious.<\/p>\n\n\n\n

RDP wrapper was the tool to do this but it stopped updating since 2017 so it won’t track any updates and newer versions pushed later.<\/p>\n\n\n\n

There is a tool called autoupdate<\/a> that rides on top of RDP wrapper<\/a> which automates the process for each version that was pushed out with the (byte location, byte values) defined in a config file called rdpwrap.ini<\/a>.<\/p>\n\n\n\n

Basically extract all the zip files to the same folder and copy the latest<\/strong> INI file along with it, run the helper routine<\/p>\n\n\n\n

autoupdate -taskadd<\/pre>\n\n\n\n
to add the startup hook (running helper\\autoupdate_<\/code>_enable_autorun_on_startup.bat does the same thing) then run the main routine<\/p>\n\n\n\n
autoupdate<\/pre>\n\n\n\n
That’s it!<\/p>\n
