regedit /s lock.reg

echo lock.reg registered successfully

5. Save the following code as uninstall.bat

@echo off

del /f lock.bat %windir%\lock.bat

echo lock.bat deleted successfully

regedit /s unlock.reg

echo lock.reg unregistered successfully

Instructions: This is adapted from the code written by an expert
uninstall.bat is for unlocking. The password here is lgx
If you want to define your own password, you can use the replacement method to replace all lgx in lock.bat with your password
There are a total of 5 files. Actually, it can all be done through one batch file.
setup.bat is used to install the CMD password lock. The principle should be understandable. It is to lock the CMD through the registry
Just run setup.bat to lock your CMD. Remember that the password is lgx and can be replaced freely.

Regarding the issue of using batch processing to encrypt or set passwords, there have been many discussions in the forum. The current conclusion is generally: the scheme is not feasible because the code of batch processing is saved in plain text. Even if the so-called encryption processing is done on the code, it is very easy to be cracked (please click here to view the specific discussion) - maybe a bit discouraging for the original poster.

Hehe, it's something from a few years ago. There are too many cracking methods, but it's quite good for increasing the interest of newbies.

I want to know what are the several cracking methods.

My way to deal with this is to download an xcmd.exe, which can do everything.

This thing...
Can I directly run CMD.exe?

I tried but it didn't work. You can still open CMD.

　　Still can run it, which proves that the previous settings are not well done or there is an error. Or it's just that the system version is different. The above locking is for computers of the Windows NT series, right?

Great stuff, I've been looking for it for a long time, haha

The simplest one is CMD /D

It's a pity that my cmd.exe is a cracked version, it won't read any registry, and it's only 98.5K in size, heh heh

My cmd.exe is 95k in size

This is good. I'm a newbie. Let's discuss again among newbies. Please give instructions from the veterans.

I think it's self-contradictory`````Is it really okay? Veteran, please teach me`````

Direct cmd /d

/D Disable execution of AutoRun commands from the registry (see below)
