在注册表HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences下怎么删除这几个键值：
TrackFoldersDirectories1
TrackFoldersDirectories2
TrackFoldersDirectories3
TrackFoldersDirectories4
TrackFoldersDirectories5
TrackFoldersDirectories8
TrackFoldersDirectories10
TrackFoldersDirectories12
TrackFoldersDirectories18
TrackFoldersDirectories19
TrackFoldersDirectories21
TrackFoldersDirectories22

用一条命令删除这几个键值，请高手指点！

look

C:\>reg delete /?

REG DELETE \\ZODIAC\HKLM\Software\MyCo /v MTU
Deletes the registry value MTU under MyCo on ZODIAC

键值后面都有数字的变量，能给我写一个BAT代码吗？我表示感谢！！

for %%i in (1 2 3 4 5 8 10 12 18 19 21 22) do (reg delete "HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences" /v "TrackFoldersDirectories%%i" /f

谢谢楼上的朋友，但是键值后面的数字经常不固定变化，不是固定的！键值后面的数字变量应该怎么写！键值变量TrackFoldersDirectories*，我想用一个通配符代替，但是注册表不支持后面的通配符！

FOR /L %variable IN (start,step,end) DO command [command-parameters]

该集表示以增量形式从开始到结束的一个数字序列。
因此，(1,1,5) 将产生序列 1 2 3 4 5，(5,-1,1) 将产生
序列 (5 4 3 2 1)。

请楼上的朋友写一个BAT代码好吗？

删除Windows Media Player默认保存位置？
应该是删除Windows Media Player打开历史记录吧

reg delete "HKCU\Software\Microsoft\MediaPlayer\Player\RecentFileList" /f >nul 2>nul

一定要那样做，在最后加个 2>nul 眼不见为尽

for /l %%i in (0,1,30) do reg delete "HKCU\Software\Microsoft\MediaPlayer\Preferences" /v "TrackFoldersDirectories%%i" /f 2>nul

谢谢8楼的朋友，已经解决了，太谢谢了，我搞了好几天了，一直没有想出办法！
