Windows 10: ctrl+shift+z is not working

I was using photoshop and suddenly ctrl+shift+z is not working. I have tried different software which REDO shortcut key is ctrl+shift+z but still not working. I uninstall all keyboard drivers and restart my laptop but still not working. I am sure this is not a hardware problem because my laptop keyboard and USB keyboard are both not able to activate ctrl+shift+z. But ctrl+shift+alt+z is ok. Any other key combinations are good but ctrl+shift+z is bad. I am so sad.

Ctrl+Shift+Z shortcut unassignable

Here are the quick answers to your questions, and following, a more develop explanations.

1. Ctrl+Shift+Z is an already existing basic, known shortcut in all Adobe softwares for the "Redo" action. I am trying to use it and it’s not doing anything. Ctrl+Alt+V is a shortcut I am trying to assign to an action in the ebook conversion software Sigil.

2. Ctrl+Shift+Z for the already existing shortcut of the "Redo" action in Adobe softwares. Ctrl+Alt+V to a specific function in Sigil.

3. Ctrl+Shift+Z in all the Adobe Creative Suite, Ctrl+Alt+V in Sigil.

Actually the issue happened when I started my work on InDesign yesterday. As you must know, Ctrl+Shift+Z is a very common, basic shortcut for the "Redo" action. After that, I opened up Sigil and tried to assign Ctrl+Alt+V to a certain action, which is the
setting I put previously in my old laptop using Windows 8.

Then, when I noticed both didn’t work, I opened a software that makes me able to remap my keyboard and assign new keystrokes, key combinations, or even macro, to a single key (SteelSeries software going with my MSI gaming laptop), and tried different key
combinations. I saw that Ctrl+Shift+A was fully detected for exemple, but if I press Ctrl+Shift+Z or Ctrl+Alt+V, the software only detects Ctrl+Shift or Ctrl+Alt, and not the letter going to it.

Here is a screenshot of some tests I did in the SteelSeries software, testing key combinations. I tried Ctrl+Shift combined with respectively those letters, in this order: w / x / y / z

As you can see, the combinations with the W and with the Y are detected, but with the X and the Z, they aren’t. And if I tried to assigned as shortcut the combinations with the X and the Z in any software, they are also not detected.





Also, Ctrl+Alt+V is not detected anywhere as mentioned, but Shift+Ctrl+V is detected. Ctrl+Alt+Z and +X are also not detected. But any letter with only Ctrl, only Shift or only Alt are detected.

So the issue is happening in multiple softwares and seems to come from some letters not being detected when used in combination with Ctrl+Shift or Ctrl+Alt. Very weird.... I hope my explanations are clear.

 

Ctrl+Z not working in any application Windows 10

Ctrl+Z (undo) doesn't work in any application. I.E., doesn't work in ms paint, notepad, etc.

I don't think it's a hardware issue because ctrl+c etc work, just ctrl+z doesn't work. Also, I was able to manually use Ctrl+Z as shortcuts in other applications. I tried making Ctrl+Z the shortcut for GeForce Experience Overlay and it worked fine.

Any suggestions on how to find which application might be hijacking ctrl+z?

Could it be a registry issue?

Did this hotkey lose priority somehow?

I tried starting in safe mode / clean boot and it didn't help.
