Comment 2 for bug 1892886

To reproduce:

Launch Windows and open a PowerShell session. Run the following:

    $url = "https://launchpad.net/juju/2.8/2.8.1/+download/juju-setup-2.8.1-signed.exe"
    $output = "juju_installer.exe"

    $wc = New-Object System.Net.WebClient
    $wc.DownloadFile($url, $output)

    .\juju_installer.exe

Exit and restart the PowerShell session to refresh the path (there's probably a better way to do this -- my PowerShell fu is not strong), then run:

    juju add-credential aws # follow prompts
    juju bootstrap aws aws

This process success on Windows Server 2012, which I believe is what we're running for CI. It fails on Windows 10, as noted above.
