Windows 10: The "ALT" - "ALT GR" keys are not working anymore after the last update. How can I solve this?

I'm using WIN 10 and a MICROSOFT 3000 v2 Keyboard.
I've already downloded and installed the right drivers. Problem persists.

Alt Gr key not working on windows 10

My Alt Gr was working just fine until a little while ago, when it just suddenly stopped working.

I was writing an essay and when I tried to send it via email, I found out I wasn't able to type the @ symbol (I just copy pasted it) and then realised I actually couldn't do anything related to the Alt Gr key.... how do I solve this?

 

Alt / Alt Gr keys are not working on physical keyboard

Hi

My ASUS Laptop's ALT and ALT GR keys are not working. It happened when I installed a Free Software named iSkySoft... That program is now uninstalled, but it still shows up in the StartUp list ( as deactivated though )

My on-screen keyborad works as well as an external USB Keyboard.

I have tried Clean Boot - no luck

I have reinstalled the keyboard driver - no luck

I ran Malwarebytes - no luck

I read that a lot of people ran into this problem, and I have followed many suggestions, without succes..

The only things I can relate to this is the iSkySoft installation or when I restart my PC, sometimes it let me choose between WIN 10 ( disc 3 ) or...... WIN 10 ( disc 3 )... ??? Somehow I have 2 identical versions of WIN 10.. Maybe thats it ??

I did install the iSkySoft late November 2016, and when I look at my list of programs, no other programs are installed near that date..

Any suggestions

/ Thomas

NB - It doesn't work in any programs

 

Alt Gr not working with the key R

Recently I started to work on a custom keyboard using MSKLC as a tool.

I am creating an IPA phonetics keyboard. To make the task easier I used as a base the built-in keyboard United States-International Keyboard, I changed most of the characters that come as default in the
Alt Gr + key combination, all the combination key worked fine except R key (Alt Gr + R) it does not respond at all. I also used other key combination
Alt + Gr + Shift +, here, the R key worked fine. Due to the problem, I decided to set the Unicode character that was causing the problem in another key combination and it worked. Since I couldn't fix the problem, I started
from scratch but the problem continues.

I wonder if there is any solution to this problem if so, I thank whoever may concern, for his/her help, beforehand.
