how do i replace corrupted keyboard drivers

asus support tell me i need to reinstall the whole of windows but hoping i can avoid that!

my issue shows on device manager under keyboard section , both

"HID keyboard device" and
"keyboard device filter " show corrupted , as does
"elan ps/2 smart pad" in the mice section

have tried the asus driver page, and no luck.

am not a pc expert so help would be much appreciated

Hi welcome to the forum
Have you tried Uninstal the drivers and restart computer they should be installed when windows starts.

Thanks for the reply.
I have tried this but doesn't make a difference. Have uninstalled via device manager when I tried. Didn't tick to delete the drivers.

You need to try deleting driver too in device manager. And restarting computer. Take will load the basic window driver for keyboard and mouse. Also delete elen TouchPad in programs and features in control panel.

Hi again
Have tried but no delete option on the keyboard driver, only an uninstall.
Have deleted the others which have been replaced but still highlighted in device manager as not working.

Is there another way to delete the driver at all?

Thanks again

Check to see there are any Class upper or lower filters for those devices. Here's how: in Device Mgr right click each device->Properties then the Details tab. Use the pull down menu to carefully look if either Class upper or lower filters are listed. If yes, select each one. Copy/paste the info that's shown for any filter into next post.

Please tell me what you find for each device

ok, here goes, there are still 3 showing corrupted but now different from the titles in original post:

for HID keyboard device, it shows 'class upper filters' and lists 2, 'aswKbd' and 'kbdclass'

for Standard ps/2 keyboard ,it shows the same 2 'aswKbd' and 'kbdclass'

for microsoft ps/2 mouse,it shows 'class upper filters' and lists 'mouclass'

no class lower filters listed for any of them


thanks.
