PSA for Toshiba Laptop Keyboard Problem

I thought it would be a good idea to inform those who have a Toshiba laptop about a problem I just encountered. My wife has a Satellite C675 that has been upgraded to Windows 10 for quite some time. Last Friday she complained about some of the keys on the keyboard not working. I had replaced the keyboard several months ago and thought that it must have gone bad. However, when I looked into it further I found the keys that did not work would work if I held down the Function Key while pressing down the non-working key. This made me think it might not be the keyboard as it seemed more like a key mapping problem than a hardware problem.

After looking at the Windows updates that were done around the time the problem appeared, I noticed that the keyboard had been updated to a Lenovo brand keyboard. After deleting the keyboard driver and restarting the computer the problem disappeared. The rub is that after doing another Windows update the Lenovo driver was reinstalled and the problem was back.

There is a way to prevent certain updates from installing in Windows 10 and the method can be found here:

In the web page referenced above a file named “wushowhide.diagcab” can be downloaded. Double clicking it will cause it to open. It allows individual updates to be marked as not being available for installation. I found the Lenovo keyboard update and toggled it off. This keeps it from installing during further update sessions. I have used this utility on my Asus laptop to keep Windows from installing a touchpad driver I did not want installed. It works very well. Sometimes I have to run the utility again as Windows might override it a few months down the road but it doesn’t happen often. Here is a web site that shows how to use this utility:

UTR Thanks for that
I will put it in my Good to Know file :iagree:

You’re welcome. That cab file I linked to is a handy tool to keep updates from installing in Windows 10. MS made it very difficult to stop individual updates in Windows 10 and I feel sorry for people that don’t have the technical knowledge to deal with these types of issues. I bet a lot of people thought their keyboards died and bought a new laptop because of this screw up by MS.

Hi, friends, I’m using Dell XPS 14z Laptop I also have some small issue my Laptop keyboard. Sometimes when I’m typing then when I press 1 button like if I press A then it will type A 2 or 3 times? I don’t why its doing like this is it really keyboard have dust that’s why it is doing like this or it is another problem. Any suggestion friends?

I would suggest looking for any keyboard driver changes done around the time the problem appeared. Also, try reinstalling the keyboard driver using the original one for your laptop from Dell’s website. If it is a driver issue then you will need to block the update causing the problem or it will keep occurring.
