Hi there,

Never take drivers from windows update unless they are intended for
Microsoft hardware.

If an updated driver is needed because the hardware does not work proper go
to the manufacturers website to look for an updated driver.

If it ain't broke: do not try to"FIX" it.

If you did take the optional drivers from windows update try booting last
known good configuration, rolling back on the driver or use system restore
or
do a windows repair installation or restore from the system backup you
hopefully made.

Best regards,
Michel Denie
