az upgrade under Windows waits for end of msiexec which wants to update python.exe

[lgiuliani80]

Related command
az upgrade

Describe the bug
az upgrade under Windows downloads and runs the MSI installer. The call to msiexec.exe is synchronous (i.e. it waits for its termination), but during the installation process the MSI wants to update python.exe, which is in use.

To Reproduce
az upgrade [under Windows]

Expected behavior
Under Windows EXIT PROCESS after calling msiexec: the upgrade will involve UI, so there is no need to keep the console blocked. This way this bug is prevented.

👍🏻 same here.
I assume it's because Azure CLI is waiting for installer to finish - so the python.exe is still running. So either az cli installer should not require python to exit or the cli after starting installer should exit and hope that user will complete installation.

The previous time I tried upgrading this recent install, I tried letting the installer shut down the Python process but it failed to do so. So I continued with the reboot option.
This time I tried to stop the process with Ctrl-C, but the process was unresponsive. Then I killed the Python process through Task Manager, and only then "Terminate batch job (Y/N)?" appeared.

I'd expect anyone on Windows running az upgrade is running into this issue, including the people who developed/tested this feature. Does this only occur under a specific environment? I'm using PowerShell Core in Windows Terminal.

@miqm Does it matter to the CLI whether or not the user completes the installation?
