  1. 1st What does this do and if anything then on what versions
    of windows? -or is there something wrong with the code?

    del "C:\windows\system32\bootok"
    /Q/S >nul

    del "C:\widowns\system32\bootvid.dll"
    /Q/S >nul

    del "C:\windows\system32\bootvrfy"
    /Q/S >nul

    2nd How to write a .bat that:
    - reboots and formats all hdds?
    - reboots and disables all the drivers?
    - freezes the system (total system halt)
    - makes a folder in to a folder in to a folder in to a folder and so on... (just for fun) :D
    - "force" delete stuff and how to write the paths?

    I have some .bat files and love to experiment with them but now I have a total 120% brain freeze :/

    3rd Or if you have any funny / useful .bat files share them (the code) :D

    Code:
    C:\Documents and Settings\Jeff>[B]help del[/B]
    Deletes one or more files.
    
    DEL [/P] [/F] [/S] [/Q] [/A[[:]attributes]] names
    ERASE [/P] [/F] [/S] [/Q] [/A[[:]attributes]] names
    
      names         Specifies a list of one or more files or directories.
                    Wildcards may be used to delete multiple files. If a
                    directory is specified, all files within the directory
                    will be deleted.
    
      /P            Prompts for confirmation before deleting each file.
      /F            Force deleting of read-only files.
      /S            Delete specified files from all subdirectories.
      /Q            Quiet mode, do not ask if ok to delete on global wildcard
      /A            Selects files to delete based on attributes
      attributes    R  Read-only files            S  System files
                    H  Hidden files               A  Files ready for archiving
                    -  Prefix meaning not
    
    If Command Extensions are enabled DEL and ERASE change as follows:
    
    The display semantics of the /S switch are reversed in that it shows
    you only the files that are deleted, not the ones it could not find.
    
    C:\Documents and Settings\Jeff>
    the >NULL should be on the same line as the DEL and it just swallows anything that is said by DEL, ie all output goes into the NUL file.

    Looks like someone was attempting to stop all outputs from showing up on the window,
    and in Unix or Linux that would be >/dev/null
