when my app install those keys and when i launch chrome, my add-on is installed,
i would like to achieve the same on Opera.

It is possible ?? because Opera is based on Chromium !

so when i was doing my tests i saw all those keys recreated every time i load opera, if i delete those keys, opera recreate them at start. !

BUT what i found no help or templates is HOW to do that for Opera !!!
I just want to create my registry keys and when i start Opera i need to see my add-on be installed !

it has to be feasible too for opera i'm sure i can add a registry value !

I guess I/we can look up PreferenceMACs on google to see what they're for.

EVEN if i remove Opera and reinstall, those keys reappear

They're probably important for some function of Opera. I wouldn't assume they're malicious.

I have more than one key under the "Opera Software" key though. And, for those, I have corresponding ones for Opera Next and Opera Developer.

In one of them, there was an extension id for an extension that was no longer installed in Opera and was never installed in the currently profile. It was an extension I made that I loaded in developer mode in "opera://extensions" many profiles ago.

I see bookmarks, vpn and crypto wallet stuff mentioned in some of them. I also see lots of extension IDs. Some of them are probably for Opera's built-in component extensions.

With that said, I still don't know what all of it is for, so good question.

Those rules are re-created inside the registry in the section extensions.opsettings !!!
