Question for the experts. Can someone help me write a batch file? VBS would also be fine. What I mean is: randomly generate a file, and open that file or run that file. Thanks. For example: if the randomly generated file is 1.exe, then run 1.exe
If the randomly generated file is 235.exe, then run 235.exe

Looks like you're trying to do some damage

Here's an example for you:

@echo off

set r=%random%.txt

echo.测试>%r%

start %r%

The filename is made up of random numbers.

For the randomly generated exe file you want, how many different kinds of code would need to be written?

Thanks, Hanyeguxing
for your code. What I want is to make a BMP image myself, say 1.BMP, then copy it to the system folder under a random new name, and import that randomly renamed name into the registry. How should that be written?

Why didn't you say so earlier? Isn't this just wasting Hanyeguxing's time and enthusiasm?

Mr. Moderator, could you please help me write one? Thanks. Renaming it with a time-based name would also be fine.

1，What requirements are there for the random name?
2，Which system folder?
3，What location in the registry?
4，What is the purpose of the whole operation?

copy "%r%" "%s%"

reg add "HKU\.DEFAULT\Control Panel\Desktop" /v Wallpaper /t REG_SZ /d "%s%" /f >nul
