Hi, Paula Marker
Welcome to Microsoft Community.
According to your description, you have a Microsoft Notebook Receiver v2.0 Model 1051 device. Then you want to know if it stores anything.
My friend, have you tried searching the name of this device?
This is just a receiver for connecting a wireless mouse, and there is actually no chip that stores any information.
It is not a USB storage device like a USB flash drive. It is just a device similar to an antenna.
