Have you tried simply doing a system restore?
To run a system restore:
Windows orb (start button)
Click view by large icons
Click backup and restore
Click recover system settings on your computer
Click open system restore
Click show more restore points
Check the restore point dates- is there a date you think may be before the
If so click on that restore point, click next and take heed of the warnings.
You will lose recently added programs and updates.
If you don't already, it is a good idea to occasionally create a
restore point manually so you can fix these sort of problems
easily. I usually create a restore point before any new installs
of any type and if not doing an install I will still manually create
a restore point once every few days (weekly minimum- yes I'm paranoid!!!).
The following link will show you how to manually create restore points
on your machine. System Restore uses a managed piece of space
on the hard drive for storing the restore points, this space can be increased
(99% sure) if required but that's another lesson.
Let us know how you go
P.S: Also try uninstalling the driver for your keyboard and then re-installing.
I would think that the deafult settings would be applied back to your keyboard
if you do this (do same for mouse if required). Come to think of it, I would probably
try that first!!!!
I knew I'd have to edit!!! Always do! The link mentioned above is: http://windows.microsoft.com/en-AU/w...-restore-point
