How to Fix ALT Codes Not Working on Windows 10 [Tutorial]

How to Fix ALT Codes Not Working on Windows 10.

Several Windows 10 users are reporting that they are suddenly unable to use ALT codes. While some users have an issue with several different Alt Codes, some users can’t use them at all. In most cases, the output is exactly the same character regardless of the alt code that is being entered. For most issues, the apparition of this issue seems to be abrupt and started occurring with no apparent trigger. As it turns out, the issue is exclusive to Windows 10 as we found no reports of the issue occurring on older Windows versions.

We investigated this particular by looking at various user reports and by analyzing the most popular fixes that affected users have deployed in order to resolve the issue. As it turns out, this particular problem can surface from a number of different causes. Here’s a shortlist of causes that could lead to the ALT codes issue.

Mouse keys don’t work when NumLock is On – One of the most common causes for this error are instances where the use of mouse keys when Numlock is on is not permitted. If this scenario is applicable, you will be able to resolve the issue by changing the default behavior so that the mouse keys are on when Numlock key is on.

The entry of Unicode is not enabled via Registry Editor – It’s possible that your Registry contains a specific key that is preventing Unicode characters from being added via Alt keys. In this case, you will be able to resolve the issue by adding an additional string value to the Input Method key.

3rd party interference – As it turns out, there is certain Voice over IP applications that are known to cause this behavior. Mumble and Discord are two apps that are commonly reported to cause this issue. Several users that encountered this problem while one of these applications was installed have reported that the issue was only resolved after they uninstalled them for good.

Special Char registry is corrupted – In rare situations, this problem can also be caused by inconsistency with the registry that keeps track of all ALT characters. If this scenario is applicable, you should be able to circumvent the problem by using the Character Map to add special characters. Additionally, you can consider 3rd party alternatives like Sharpkeys or Keytweak

This tutorial will apply for computers, laptops, desktops, and tablets running the Windows 10 operating system (Home, Professional, Enterprise, Education) from all supported hardware manufactures, like Dell, HP, Acer, Asus, Toshiba, Lenovo, and Samsung.

Not only did this not fix my ALT code now, I quite literally cannot use my numpad.

I don't know what the point was of enabling the mouse like you did in the beginning. When I did that it made the ALT Codes unusable until I disabled it again.

Does not fix the problem on a Zephyrus G14 _ 10 April 2022.

Update: So yeah, apparently you can't alt code on a laptop without numpads. But on Windows 10 you can enter emojis with Win+.(dot)

[SattamAlmalki]

Thanks this really helped. Alt key used to stop registering while alt taping between apps and sometimes doesn't work. This fixed it. I have no idea what made it that way

Hi everyone. I think your keys are not working when you used with Alt-Gr Combination. This issue's reason Yandex Browser. If you are using yandex browser, it have some hotkeys. And when you can delete this browser from your system, then problem will have fixed. And Yandex support page are saying "Restriction. You can't disable and configure keyboard shortcuts in Yandex Browser". I cant believe it. awful !!! So, excuse my English :) my skills is not good enough

I tried these methods but unfortunately, nothing worked.. so random thing I did, I went to MS Word, pressed the 'Alt + LShift + Num Lock', then there's this notif that came up at the upper left corner of MSWord asking about the mousekeys setting thing
I just clicked okay (or enable?.. sorry my memory is goldfish) then I tried turning the num lock on and off, for some miracle it worked :)
I'm not sure if this will work for y'all but I'm putting it out here just in case well hopefully it does, who knows
Honestly, idk if opening MS Word has any relevance at all but yeah

[jonatan]

A dozen steps in different windows is simple? Leave it to Windows to make something that should be simple complex.

My alt key isn't working at all. I set it to a macro key using the virtual keyboard and it's still not working.
