.SYNOPSIS
Edits Signed WDAC policies deployed on the system (Windows Defender Application Control)
 
.LINK
https://github.com/HotCakeX/Harden-Windows-Security/wiki/Edit-SignedWDACConfig
 
.DESCRIPTION
Using official Microsoft methods, Edits Signed WDAC policies deployed on the system (Windows Defender Application Control)
 
.COMPONENT
Windows Defender Application Control, ConfigCI PowerShell module
 
.FUNCTIONALITY
Using official Microsoft methods, Edits Signed WDAC policies deployed on the system (Windows Defender Application Control)
 
.PARAMETER AllowNewAppsAuditEvents
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 MergeSupplementalPolicies
Merges multiple Signed deployed supplemental policies into 1 single supplemental policy, removes the old ones, deploys the new one. System restart needed to take effect.
 
.PARAMETER UpdateBasePolicy
It can rebootlessly change the type of the deployed signed base policy. It can update the recommended block rules and/or change policy rule options in the deployed base policy.
 
.PARAMETER SkipVersionCheck
Can be used with any parameter to bypass the online version check - only to be used in rare cases
