Reinstall Minecraft correctly?

I would like to reinstall my Minecraft (Minecraft Java), I would like to know how to do it correctly, what exactly you have to uninstall there etc. I already know how to download it again after the deinstallation, it is only about whether I only have the Uninstall Minecraft Launcher or something else.

So you can uninstall the game via the program management. Usually there are still some remaining folders, but since you want to reinstall it anyway, it doesn't matter

To delete Minecraft correctly, delete the .minecraft folder in the Appdata folder.

!CAUTION! All data like worlds, server list, versions etc. Will be lost!

And of course uninstall the Minecraft Launcher.

Thank you very much!

By the way, I mean the roaming folder, not the Appdata folder. My mistake.

And then simply reinstall the minecraft launcher on the official website, right?

Yes.
