Touchpad is not working anymore

If by INF you mean the info file on the Windows drive, that's only a
text file for how Windows will use the hardware.  If the Windows update
changed the firmware in the hardware, then that may well affect Fedora's
use of the hardware, too.  It depends on what it changed.

You can see if an updated Fedora kernel was the cause of your problem by
booting up using an older kernel.  Use the boot menu, and pick one.  By
default, Fedora keeps 2 or 3 kernels installed, for just this sort of
thing.  Don't remove old kernels when you install a new one, just to
save space, you create headaches for yourself.

I tend to keep 4 or 5 old kernels installed.  That lets me go back and
check on things I haven't noticed.

George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
