.SYNOPSIS
Helper script for installing/uninstalling Microsoft Defender for Downlevel Servers.
.DESCRIPTION
On install scenario:
It first removes MMA workspace when RemoveMMA guid is provided.
Next uninstalls SCEP if present and OS version is Server2012R2
Next installs two hotfixes required by the MSI (if they are not installed)
Next installs the Microsoft Defender for Downlevel Servers MSI (i.e. md4ws.msi)
Finally, it runs the onboarding script, if provided using the parameter OnboardingScript.
Please use the script for Group Policy as it is non-interactive; the local onboarding script will fail.
On uninstall scenario:
It will run the offboarding script, if provided.
Uninstalls the MSI unless IsTamperProtected is on.
Removes Defender Powershell module, if loaded inside current Powershell session.
.INPUTS
md4ws.msi
