Mods for WAU (if Network is active/any Winget is installed/running as SYSTEM):

Custom script should be placed here.
A script Template _WAU-mods-template.ps1 is included to get you started.
Rename it to _WAU-mods.ps1 if you want to activate/run it via Winget-Upgrade.ps1.

Pre/During/Post install/uninstall:

Custom scripts should be placed here.
A script Template and Mods Functions are included as an example to get you started...

Scripts that are considered:
AppID-preinstall.ps1, -upgrade.ps1, -install.ps1 or -installed.ps1.
(-preuninstall.ps1, -uninstall.ps1 or -uninstalled.ps1 - if used together with Winget-Install).

Runs before upgrade/install: AppID-preinstall.ps1
Runs during upgrade/install (before install check): AppID-upgrade.ps1/AppID-install.ps1
Runs after upgrade/install has been confirmed: AppID-installed.ps1

The -install mod will be used for upgrades too if -upgrade doesn't exist (WAU first tries & $Winget upgrade --id and if the app isn't detected after that & $Winget install --id is tried).

AppID-install.ps1 is recommended because it's used in both scenarios.

Winget native parameters:

Another finess is the AppID followed by the -override suffix as a text file (.txt).

Example:
Canneverbe.CDBurnerXP-override.txt with the content ADDLOCAL=All REMOVE=Desktop_Shortcut /qn

This will use the content of the text file as a native winget --override parameter in WAU upgrading.
