More Info

There is a problem with all app execution aliases on Windows 10 for apps installed via the Windows Store inside of git-bash. This issue is specific to git-bash (i'm not sure if there is a separate repo to handle terminal issues).

They are located in a folder under the user's local data here:

%LocalAppData%\Microsoft\WindowsApps\

Which just contains 0 byte executables that act as shortcuts (or maybe symlinks?) to the actual executables found in this directory:

C:\Program Files\WindowsApps\

While this directory appears highly locked down, such that an administrator cannot even open it, it appears to allow traversal rights so you can actually open the apps themselves inside of subfolders (provided you have a way to discover the path... process > details > open file location) like this:

C:\Program Files\WindowsApps\Microsoft.WindowsTerminal_1.0.1401.0_x64__8wekyb3d8bbwe

For many executables, a possible workaround is to install the software directly and disable the link to the Windows Store. However, this is not possible for apps deployed exclusively through the windows store like WindowsTerminal and WinGet

Here's an example in bash vs cmd:

I can confirm this issue. I can also say that git handles them fine (I've modified the shebang of git p4 a little, it launches the specified interpreter),but MSYS2 doen't like them.

There also seems to be some rather current discussion about IO_REPARSE_TAG_APPEXECLINK support on the cygwin mailing list and the MSYS2 issue tracker.

I think I have a fix for this, in msys2/msys2-runtime#27.
