Brief description of your issue

This installer has Git as a dependency. It finds Git in the Windows Path during install to register itself. But the Windows Path in most Command Prompt and PowerShell windows appears to only update at window launch. One window must be opened for the dependency install, and then another window opened for the main package install. Observed in

• https://github.com/microsoft/winget-pkgs/pull/90133

Similar behavior was observed in this PR - the installer completed, but validation failed as it used the same PowerShell window, and thus couldn't find Git in the Windows Path.

• https://github.com/microsoft/winget-pkgs/pull/90517

Steps to reproduce

For 90133 - On new system, modify the package's manifest to have Git.Git as a dependency, then install in a VM.

Actual behavior

The installer will error "Could not find Git; can not register Git LFS."

Expected behavior

Winget could help the client window to update its local Windows Path variable from the registry, so subsequent installers could install successfully, and programs run from the same window could find Git to execute successfully.
