# Clearing Device History

## Cleaning our System of Device Information

While using a DMA device. You will eventually power on a Windows system with the stock gateware installed on your card. Even after flashing your device, this record of the original gateware is kept on the OS. We need to clear this.

Start by opening Device Manager. From here, we'll go to View->Show hidden devices. 

Now, our stock gateware device will be visible under the "Other Devices" subsection. We want to identify our device using its hardware ids and delete it.

It is very important that you do not forget this step. Anticheats will ban you for having a device history with the stock gateware for most DMA cards.
