This is a known problem across all versions of the Windows Operating System, so having a specific version of Windows does not leave you susceptible to this problem. Since there are so many possible causes of this problem, there are also just as many possible solutions. If the number keys on your keyboard have stopped working, the following are the most effective solutions that you can use to try and resolve the problem:

Method 1: Unplug the keyboard and plug it into a different USB port

More often than not, this problem is caused by the affected keyboard’s USB input or the USB port that the affected keyboard is plugged in to accruing dust, interfering with the connection between the keyboard and the computer and leading to the keyboard’s number keys not working. If that is the case, all you need to do in order to get rid of this problem is:

Method 2: Uninstall (and then reinstall) the keyboard’s drivers

When the computer boots up, it will automatically detect the affected keyboard and download and install the latest drivers for it. As soon as the drivers have been successfully installed, check to see whether or not the issue has been resolved.

Method 3: Disable the Turn on Mouse Keys option in the Ease of Access Center

Many people suffer from this issue simply because they have the Turn on Mouse Keys option enabled on their computer. If this is the cause of this issue in your case, all you need to do in order to get the numbers on your keyboard working again is disable the Turn on Mouse Keys feature. In order to do so, you need to:

Note: If you click on Make the keyboard easier to use and see that the Turn on Mouse Keys option is already disabled, enable it, click on Apply followed by OK, click on Make the keyboard easier to use once again, disable the Turn on Mouse Keys option, click on Apply and then click on OK. This should fix the issue if the Turn on Mouse Keys option was already disabled on your computer from the beginning.

Method 4: Replace your keyboard

If all else fails, you might just be dealing with a hardware failure, in which case nothing you do will be able to make this issue go away (unless you have amazing mechanical skills and can successfully open up and fix a keyboard, of course). In such cases, the recommended course of action is to simply let go of the offending keyboard and get a new one.
