How to reset statistics?

Hello Doug,

If you are looking to start over and play again, you can delete the save from everywhere. However, as mentioned above you will still keep achievements.

You can manage your data for individual games through My games & apps on your Home screen. Here's how:

1. On Home, select My games & apps.
2. Highlight the game, press the Menu button
   on your controller, and then select Manage game & add-ons.
   
3. In the menu on the left side of the screen, scroll down to Saved Data, then highlight the saved data for your gamertag on the right and press the
   A button on your controller.
   
4. You'll be prompted to confirm deletion of this game save data:
   • Delete from console removes the local copy of this save. You can get it from the cloud the next time you play.
     
   • Delete everywhere removes your saved data from this console, the cloud, and all other consoles you play on.
     
   • Cancel leaves your data intact.

Thanks,

Brad

Yeah, that was it. Thanks for letting me know!

What stats are you looking to reset? There isn't a way to reset you Gamerscore in a game if that is what you are talking about.

Go to the "run" command and type in wsreset.exe. I did that today hoping to get the statistics for MS Freecell to update the games won/lost but it didn't work. Games won is still the same as it was under Windows 8.1.

I think
THIS will help you out, if I am reading your question right.
