Worklet: Install / Upgrade to Microsoft Edge Chromium on Windows

This worklet by default will install the latest, stable version for Windows 64-bit. You can also modify $Channel to install the Dev or Beta instead. Here’s the description of the channels:

It has been tested on systems without any version of Edge pre-existing (ie. Win7) and on others that have the original version of Edge (whose end of life is March 9, 2021) such as Win10 v1909 & v2004.

Evaluation:

$software = "Microsoft Edge";
$installed = (Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where { $_.DisplayName -eq $software }) -ne $null

If(-Not $installed) {
	Exit 1
} else {
	Exit 0
}
