删除：

set "file=HIVESY.INF"
cscript -nologo -e:jscript "%~0"<"%file%">"New_%file%"
pause & exit/b & rem */

txt = WScript.StdIn.ReadAll();
txt = txt.replace(/^\[Addreg][\s\S]+?(?=^\[)/img, "")
WScript.Echo(txt)

如果[AddReg]节名连续出现，截取或删除[AddReg]节会出现遗漏
可能性虽然不大，还是改一下。

    截取：

@echo off & setlocal enabledelayedexpansion
set "file=HIVESY.INF"
set "key=[AddReg]"
(for /f "delims=" %%a in ('findstr /n .* "%file%"') do (
    set "str=%%a"
    set "str=!str:*:=!"
    if "!str:%key%=!" == "" (
        set flag=1
    ) else if "!str:~,1!" == "[" set "flag="
    if defined flag echo,!str!
))>"New_%file%"
pause
复制代码

删除：
第10行改成：

    if not defined flag echo,!str!
