以系统权限执行Regedit
本帖最后由 diddom 于 2012-5-31 07:33 编辑虽然这是老掉牙的东西,但是我想对一些新手可能有点帮助
一般我们执行程式的权限大都在管理员
但是当我们需要执行Regedit,想看 SAM
你却发现看不到, 这时我们可以靠正统的方法去实现
执行後就可以看SAM了
叫出工作管理员,你会发现regedit的权限是"SYSTEM"
希望此文能带领你进入权限的入门

这主题的source於5/17/2012更新
代码收下了，正好研究下 LZ的好东西真多。 还有一招不用编程的办法也能读写SAM键,那就是直接在这个键上右键---->权限---->把当前用户名的所有权勾上,再重新打开regedit即可......
也可以伪编程,生成一个INI权限描述文件,再用regini.exe去执行,嘿嘿...... 对Win7不起作用...... 多谢
