🎯 Usage Examples

Basic GPO Configuration

# Enable dual listing mode
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Romanitho\Winget-AutoUpdate" -Name "WAU_UseDualListing" -Value 1

# Add applications to whitelist
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Romanitho\Winget-AutoUpdate\WhiteList" -Name "1" -Value "Microsoft.Teams"
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Romanitho\Winget-AutoUpdate\WhiteList" -Name "2" -Value "Adobe.Acrobat.Reader.64-bit"

# Add application to blacklist (overrides whitelist)
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Romanitho\Winget-AutoUpdate\BlackList" -Name "1" -Value "Microsoft.Teams"

Decision Logic

1. Check Version: Skip apps with "Unknown" version
2. Check Blacklist: If app is in blacklist → SKIP (blacklist wins)
3. Check Whitelist: If whitelist exists and app is in whitelist → UPDATE
4. No Whitelist: If no whitelist configured → UPDATE (not in blacklist)
