How to turn Numlock ON permanently.

You can use autohotkey app and add this line in any startup autoloading script: SetNumLockState, AlwaysOn

download autohotkey (a popular file with IT guys, it allows you to create hotkeys to do most anything in windows).

https://www.autohotkey.com/

Install autohotkey by running the .exe file.

Now when you right click on the desktop, a new right click menu item will be there: New | AutoHotKey script

Choose that, and a brand new script file with .ahk extension will drop right there on your desktop. Rename it to anything you like, such as NumlockAlwaysOn.ahk

Rightclick on that file and choose Edit, and it will open in notepad.

There will be some necessary gobble de gook lines, leave them there and add these two lines below them:

SetNumLockState, AlwaysON

Return

(If you don't include Return, then the script would stay running until you shut down the computer)!

Save that file on your desktop. When you double click that file, Numlock will stay on and you can't turn it off.

Unless, to turn numlock off, create a new .ahk file (without the above 2 added lines) and add these instead:

SetNumLockState, AlwaysOFF

Return

Double click either .ahk script file to turn Numlock On or Off

------------------------

You can run either script file automatically when you boot up the computer, if you make a shortcut of ONLY ONE of those two .ahk files and drop it into:

C:\Users\All Users\Microsoft\Windows\Start Menu\Programs\StartUp

(Any file you put in there will automatically run on startup).

--------------------------

The Numlock ON mode is often used for when the MSFS user wants to bind saving newly created Custom Camera views using Control numpad 1, Control numpad 2, etc. And then bind Load Custom Camera 1 to: numpad 1, numpad 2, etc. (without the Control key), etc.

When in a high concentration part of a flight and you are changing the views around, you want to make sure those keys do change the views around instead of doing something else that will interrupt your flight! In other words, keep Numlock always ON.
