Commands to lock mouse and keyboard under Windows

How to achieve under Windows without any third-party software
Only using Windows built-in commands, functions, etc. to lock the mouse and keyboard

My own research result is that rundll32.exe user32.dll,ClipCursor can lock the mouse but not every time successfully. I don't know why. Maybe I'm not familiar with how to use it yet. Please teach those who know how to use it.

First, I'll help you top it. Although this question doesn't seem related to DOS, I still hope to find an answer here.

Is really no one interested?

Oh... I don't understand why the original poster locked the most important input devices, the mouse and keyboard. After locking, they can't move, which is like a system crash?! I only know that using rundll32.exe user32.dll,LockWorkStation. This will show the interface to select the user to log in. The mouse and keyboard can still move, but if the system password is set, then people who don't know the password can't log in and return to the desktop, so this can achieve the purpose of preventing outsiders from using it.

Hehe, of course I have my own thoughts. A question: when you're researching something and almost have the answer, do you want to know the final answer or do you choose to give up? As far as I know, it can definitely be achieved using user32.dll, but I just don't know the specific parameters. So I want to ask those who know and also let everyone know. A small tip isn't bad, right? I just hope to discuss and make progress together, no other purpose. Unlike what others say: What do you want to do? Be a hacker to bluff people? Do you need to be so troublesome to bluff people? There are so many such software everywhere. But this makes me feel even more necessary to know the answer. Because when your machine is "bluffed" and the mouse doesn't work, do you need to restart or even find third-party software? It's so troublesome. But if you know that entering a command can解除 it, then what will happen? Just like the Slammer virus, it will make your machine restart. Isn't it very headache-inducing? But if when it makes you restart, you enter shutdown -a to cancel it, will you still feel headache? Haha, it seems I've drifted away. Let's get back to the mouse issue. As far as I know, rundll32.exe user32.dll,ClipCursor followed by parameters can lock the mouse, but it's not always successful because I don't know the specific parameters. I just tried using 1 or 1,1, etc. And I don't know the format of the parameters that follow, but it seems that using 0 can cancel the lock. That's all I can provide. I hope those who are interested can go back and try it themselves. Also, I hope those who know the answer can tell everyone. Thanks.
