TermsrvPatcher simplifies the process of patching the termsrv.dll file for enabling concurrent remote desktop sessions on non-server Windows editions. It also eliminates the need for manipulating termsrv.dll permissions by performing the file write operations as TrustedInstaller (using the NSudo Devil Mode) and it also takes care for stopping and starting the Remote Desktop Service.
Multiple find/replace patterns and wildcards are supported, see the included patchfile for examples.
Remote desktop can directly be enabled from the application, including the network level authentication setting. It also allows to configure additional options for enabling blank password logon or multiple sessions per user.
A scheduled task can be added to patch termsrv.dll at startup in unattended mode (runs the patcher with the command line parameter "-unattended"). This may re-enable concurrent remote desktop sessions after Windows updates as long as a valid patch is available in the patchfile (taking advantage of the wildcard support for patches increases the chances that patches also match after Windows feature updates).
For legal reasons, only example patches are available in the included Patches.txt file.
