Note that this version of Concurrent RDP Patcher patches the DLL on Windows 7 RTM, Service Pack 1 and update KB3003743 which was released in October 2014.
For four years the termsrv.dll file wasn’t changed and the Concurrent RDP Patcher worked fine from October 2014 onwards. Recently though, Microsoft made changes to the DLL and it broke the patcher with Rollup update KB4462923 released in October 2018. If you are still running with that update or have not yet installed any Rollup updates beyond January 2019, we have a dedicated Concurrent RDP Patcher that works with it.

Unfortunately, it’s only been a few short months and Microsoft has yet again changed the termsrv.dll to break the patcher once more. The offending update is Rollup update KB4486563 released in February 2019. The January 2019 Rollup Preview (KB4480955) also contains the same DLL file. We have created a new patcher that should work for this latest update.

NOTICE: Please be aware that the Feb 2019 version of the patcher has not been extensively tested so it should be considered as alpha/beta software and could contain bugs. Please use it with care and at your own risk. Of course, we welcome any feedback on how this latest patched version works for you.
Concurrent RDP Patcher fixed versions work on 32-bit and 64-bit Windows 7 Service Pack 1 and newer. Starter, Home Basic, Home Premium, Professional and Ultimate are supported, but not Enterprise. We will do our best to update the Concurrent RDP Patcher if there are any more updates to the termsrv.dll library in 2019. Support for Windows 7 ends in January 2020 so there aren’t likely to be any more updates after this time.
April 2019 Test Version
Microsoft has updated the DLL for the second time in 2019 and enjoys making life more difficult! Rollup update KB4493472 will break things again. The below patcher is a test version and should be treated as such on 64-bit and 32-bit Windows 7 so please take care when using it.
For Windows 8
Windows 8 and 8.1 users please download the patched termsrv.dll file from here and edit the following registry keys at HKLM\System\CurrentControlSet\Control\Terminal Server.
Replace this file in C:\Windows\System32
