Open the Device Manager and look for a device that looks like your keyboard.
Open the Device Manager, select **View → Devices by container**, and look for an entry with your keyboard's name.

Right-click it and hit **Uninstall device**. Make sure to tick **Delete the driver software for this device** first.
Right-click each entry and hit **Uninstall device**. Make sure to tick **Delete the driver software for this device** first if it appears.

Click **Action → Scan for hardware changes**. At this point, you should be able to type again. Double check in Zadig that the keyboard device(s) are using the `HidUsb` driver. If so, you're all done, and your board should be functional again! Otherwise, repeat the process until Zadig reports the correct driver.

If so, you're all done, and your board should be functional again! Otherwise, repeat this process until Zadig reports the correct driver.
?> A full reboot of your computer may sometimes be necessary at this point, to get Windows to pick up the new driver.
## Uninstallation
Uninstallation of bootloader devices is a little more involved than installation.
Open the Device Manager, select **View → Devices by container**, and look for the bootloader device. Match up the USB VID and PID in Zadig with one from [the table below](#list-of-known-bootloaders).
Find the `Inf name` value in the Details tab of the device properties. This should generally be something like `oemXX.inf`:
![Device properties showing the Inf name value](https://i.imgur.com/Bu4mk9m.png)
Then, open a new Command Prompt window as an Administrator (type in `cmd` into the Start menu and press Ctrl+Shift+Enter). Run `pnputil /enum-drivers` to verify the `Inf name` matches the `Published Name` field of one of the entries:
![pnputil output with matching driver highlighted](https://i.imgur.com/3RrSjzW.png)
Run `pnputil /delete-driver oemXX.inf /uninstall`. This will delete the driver and remove it from any devices using it. Note that this will not uninstall the device itself.
As with the previous section, this process may need to be repeated multiple times, as multiple drivers can be applicable to the same device.
!> **WARNING:** Be *extremely careful* when doing this! You could potentially uninstall the driver for some other critical device. If you are unsure, double check the output of `/enum-drivers`, and omit the `/uninstall` flag when running `/delete-driver`.
## List of Known Bootloaders
This is a list of known bootloader devices and their USB vendor and product IDs, as well as the correct driver to assign for flashing with QMK. Note that the usbser and HidUsb drivers are built in to Windows, and cannot be assigned with Zadig - if your device has an incorrect driver, you must use the Device Manager to uninstall it as described in the previous section.
