Build and ship an actual binary named wt that just launches WT #6860
Conversation
Due to a shell limitation, Ctrl+Shift+Enter will not launch Windows Terminal as Administrator. This is caused by the app execution alias and the actual targeted executable not having the same name. In addition, PowerShell has an issue detecting app execution aliases as GUI/TUI applications. When you run wt from PowerShell, the shell will wait for WT to exit before returning to the prompt. Having a shim that immediately re-executes WindowsTerminal and then returns handily knocks this issue out (as the process that PS was waiting for exits immediately.) This could cause a regression for anybody who tries to capture the PID of wt.exe. Our process tree is not an API, and we have offered no consistency guarantee on it. Fixes #4645 (PowerShell waits for wt) Fixes #6625 (Can't launch as admin using C-S-enter)

nope, createprocess returns 1 on success; definitely don't do this

Wait, the way this is, won't the commandline windowsterminal.exe processes be windownterminal.exe wt.exe new-tab ...?

So actually, no! The first argument to CreateProcess is the actual executable to run, and the second is its entire commandline. That includes the first argument, usually the program name, that comes in as argv[0].
There are some tools (usually linux ones) that detect what identity they were launched as and do something different depending on what it was. Busybox is a great example. It’s one binary that contains sh, ls, rm, cat, ... and at runtime decides which one to be based on how you invoked it.

Anyway, all that is possible because the first argument, usually the program name, can vary and is detectable by the application. Because of that, though, it must be specified when creating a process!

Due to a shell limitation, Ctrl+Shift+Enter will not launch Windows
Terminal as Administrator. This is caused by the app execution alias and
the actual targeted executable not having the same name.
In addition, PowerShell has an issue detecting app execution aliases as

wait for WT to exit before returning to the prompt. Having a shim that

This could cause a regression for anybody who tries to capture the PID
of wt.exe. Our process tree is not an API, and we have offered no
consistency guarantee on it.
VALIDATION
Tested manual launch in a number of different scenarios:
Fixes #4645 (PowerShell waits for wt)
Fixes #6625 (Can't launch as admin using C-S-enter)
