I’m well aware of these. Winget is a disaster of a package manager. All of them just download and run conventional installers with none of the tidiness you get with real package managers on systems actually designed for them. It’s fun watching winget update an app that already updated itself. Do any other GPU vendors typically distribute their drivers through winget?

But the real answer here is Windows Update, which Nvidia does publish drivers through. But not game ready versions, only WHQL certified builds.
