Clear All Event Logs in Event Viewer in Windows — Clear All Event Logs in Event Viewer in Windows contains a batch file to automate and simplify the process of deleting all of the Event Logs in Event Viewer in Windows.
Put a comment in a batch file — REM must be followed by a space or tab character, then the comment. TCC will ignore everything on the line following the REM, including quotes, redirection symbols, and other commands (see below for the exception to this rule). If ECHO is ON, the comment is displayed. Otherwise, it is ignored. If ECHO is ON and you don't want to display the line, preface the REM command with an at sign [@]. You can also place a comment in a batch file by starting the comment line with two colons [::]. In essence this creates a batch file "label" without a valid label name.
