Factory resetting an Xbox

So even if I delete all of my games the progress will be saved with the accounts?

Hello there!

Regarding your question, there are two options when you try resetting your console. The first option you need to try is " reset and keep my games & app" with this option, your games stay installed but your console resets itself and removes the accounts you have.

The second option is "reset and remove everything" when you select this option your installed games are removed when the console resets, which means you will have to install them again.

As for your progress that is automatically linked to the cloud with your Microsoft account; which means if you play online you do not have to worry since you will not lose any data. You will just need to sign back in with the correct Microsoft account and you will get everything back just like it was before.

Resetting your console to its factory defaults erases all accounts, saved games, settings, and home Xbox associations. Anything not synchronized with Xbox Live will be lost. Your console syncs with Xbox Live automatically when it’s connected with the
service, so if you've been offline for a while, you'll need to connect to Xbox Live before taking these steps.
