@burnout426 said in Opera automatically sets itself as the default browser on installation (Windows):

Haven't messed with winget and don't really know how it's all set up, but there might be a way to pass --setdefaultbrowser=0 to the winget upgrade command you use to upgrade Opera. Or, if you do winget upgrade --all, there might be some file that you can put --setdefaultbrowser=0 in for Opera so its upgrade command passes that to Opera's installer.
But, that's assuming winget makes use of the Opera installer at all. If the Opera winget package is just Opera's install files that winget just extracts or something, winget would need to support not making Opera the default browser on upgrade.
Something to investigate though.

For Winget you have to use the --override parameter.

For example : > winget update --override "setdefaultbrowser=0 desktopshortcut=0 startmenushortcut=0 pintotaskbar=0 launchbrowser=0" Opera.Opera

The installer parameter copyonly=[0|1], is usable too but not sure of what append after this kind of install.
: If true, the installer will only copy the files to the installation folder and will otherwise not perform any modification on the system.

For the > winget update --all I use > winget update --silent --accept-package-agreements --accept-source-agreements --all --wait --disable-interactivity --override "setdefaultbrowser=0 desktopshortcut=0 startmenushortcut=0 pintotaskbar=0 launchbrowser=0" and as many installer ignore unknown parameters it works most of the time.

After trying few things there is some changes that needs to be done for Winget to work properly :

1. I wrote a script with multiples winget update in a row, beginning with some specific overrride options, then doing the global update.
2. Trying with the last update the mentioned parameters in the --help option with the installer. apparently you need to add -- in front of the options to be functional (it wasn't clear)
3. Winget accepts --override only with one package at a time

So, it's my final version in my script :

winget update --silent --accept-package-agreements --accept-source-agreements --disable-interactivity --override "--setdefaultbrowser=0 --desktopshortcut=0 --startmenushortcut=0 --pintotaskbar=0 ----launchbrowser=0 --silent" Opera.Opera
winget update --silent --accept-package-agreements --accept-source-agreements --all --wait --disable-interactivity 

If this doesn't work for you, my last solution is to block the version used in Winget so it'll ignore any future update.
