Disable keyboard driver on win11

Today I ran into a hardware bug which was really annoying. My laptop keyboard inputed r constantly and I couldn't fix it. I think it's because the motherboard is rotten. I could not open and remove the corrupted part. So the easiest way is disabling keyboard driver and use external keyboard.

It takes 2 steps to disable keyboard driver.

1. Open Devide Manager and Uninstall keyboard device. For me, it's PS/2.
2. Then, run cmd as administrator and execute command sc config i8042prt start= disabled

Then, after rebooting, the build-in keyboard will be disabled.

Re-able the driver

Run cmd as administator and execute command sc config i8042prt start= auto.

After rebooting and the keyboard driver will be loaded.
