How to increase the remote login limit on Windows 10?

By default, Windows 10 only allows 1 remote login at any time. If the second user is trying to login remotely, he/she will get the following warning message:

Another user is signed in. If you continue, they'll
be disconnected. Do you want to sign in anyway?

Unfortunately, Windows 10 Pro does not offer any configuration to change the above limitation. But there 2 workarounds to avoid it.

1. Modify termsrv.dll:

Stop TermService service

Edit termsrv.dll
    Replace 39 81 3C 06 00 00 0F 84 73 42 02 00
    With B8 00 01 00 00 89 81 38 06 00 00 90

Start TermService service

2. Install RDP Wrapper Library

Download RDP Wrapper Library
   from https://github.com/stascorp/rdpwrap/releases

Run install.bat

Run RDPConfig.exe to ensure no errors.

Note that if you download RDP Wrapper Library with Chrome, you will get the "RDPWrap-v1.6.2.zip is dangerous, so Chrome has blocked it" error.

You can use another Web browser to download it. Or take the option 1.
