.SYNOPSIS
Automate a lot of tasks related to WDAC (Windows Defender Application Control)
 
.LINK
https://github.com/HotCakeX/Harden-Windows-Security/wiki/WDACConfig
 
.DESCRIPTION
Using official Microsoft methods, configure and use Windows Defender Application Control
 
.COMPONENT
Windows Defender Application Control
 
.FUNCTIONALITY
Automate various tasks related to Windows Defender Application Control (WDAC)
 
.PARAMETER AllowNewApps_AuditEvents
Rebootlessly install new apps/programs when Signed policy is already deployed, use audit events to capture installation files, scan their directories for new Supplemental policy, Sign and deploy thew Supplemental policy.
 
.PARAMETER AllowNewApps
Rebootlessly install new apps/programs when Signed policy is already deployed, scan their directories for new Supplemental policy, Sign and deploy thew Supplemental policy.
 
.PARAMETER SkipVersionCheck
Can be used with any parameter to bypass the online version check - only to be used in rare cases
