There may still be an MSIX specific limitation in play here, but the steps in the issue description will not work as expected in any version of PowerShell.

The ‘reopen shell’ operation that I missed in the issue description

Now, i can understand MSIX specific limitation.

run command in powershell installed from msix, and reopen shell and see $env:TEST_URL

run command in windows powershell, and reopen shell and see $env:TEST_URL

@iSazonov This is MSIX specific. The MSIX sandbox virtualizes some registry access. [Environment]::SetEnvironmentVariable('TEST_URL', 'http:url', 'User') writes the value to the User registry, which is virtualized. So the change is not persistent across sessions.
