How do I find out if a controller is mine?

Hi,Tyler! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

You can check if you have previously assign that controller to your profile

Press the Xbox button  to open the guide.

Select Profile & system > Settings > Devices & connections > Accessories.

Select the controller, and then the More options icon (…). Assigned to shows the current account assigned to that controller.

Other method would be to check the serial number. I do not know if you ever checked that though

i just got mine today now trying to find out how to add or invite friends to do it.. if so ill send one

Hi Francois, my name is Oskayra independent consultant.

I am very sorry that you are having trouble finding your controller. Here are some steps you can try:

1. contact the shipping company: The shipping company should be able to track the shipment of your controller. If they don't have it, they can help you initiate an investigation. If not, you may be able to sue.

2. Contact Microsoft. Microsoft should be able to provide you with more information about the status of your repair.

3. File a complaint. If you cannot find your controller, you can file a complaint with the carrier or Microsoft.

You can contact Xbox Support directly for assistance with the process.

If i'm looking for something then i find using my eyes helps a great deal.

Other than actually coming to your house & looking for it for you i'm not sure what you want us to do.

Your stats tab in the menu shows how long you have been alive in Skyrim, how long you have been a werewolf/vampire, and other such stuff. Your last save file shows how many hours: minutes: seconds you have been playing as that character. My last character
has been alive for 2 years and save time is 792:34:12 and still playing as he just finished Peryites quest and got his "Spell Breaker" shield.
