看了一下时间，应该是2000年的东西了，如果没记错，应该取自“电脑爱好者”

作用是枚举并可选择性删除“运行”的历史记录。
删除：HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMR下的键值。
注意：“重启”或“注销”或结束“explorer进程”后看效果。

键下值集具规律性，所以不用WMI可枚举。

兄收藏了这么多的VBS好东西啊??
顶啊!!

MRU的命名有规律的，呵呵

好像用shell.RegRead只能读取已知键值，而WMI才是真正的枚举。

RunMRU键下键名规律为a、b、c、d.......
并且还有MRUList的值提供读取范围

由此规律 键下键名都成了已知项。

强,看完上述评论后,反正我是在云里雾里,先不管,保存下来先!
我想我还没到那个地步吧!!
多谢!

能给个分析吗？

始终不能领悟WMI

XP下试了只删了一项记录后就不行了~按照提示删除所有记录后查看运行记录只删了一项~再运行就提示“There are no entries to clear”
查看 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU 所有键值都没了~

输入a 就删除a对应的值这一项没什么错误啊，不明白你所谓的“就不行了~”是什意思，另外你说的全是正常现象。
"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU 所有键值都没了~" 全部删除当然所有值都没了。更当然“There are no entries to clear”了。

(Reboot after OK)已经提示你重启后看效果了，你自己没注意而已。另外你不重启的话“注销”结束“explorer”进程都可以。
