Some time last months all the Thumbnails in Explorer disappeared for me. It might have coincided with me installing VLC Player on Vista. Either way, it sucked because I had family photos withthumbnails next to videos taken with the same camera with nothumbnails. It's no fun to lose functionality.
上个月的某个时间，资源管理器中的所有缩略图都对我不见了。 可能是我在Vista上安装了VLC Player时发生的。 无论哪种方式，它都很烂，因为我的全家福照片带有缩略图，而该照片是在使用同一相机拍摄的没有缩略图的视频旁边。 失去功能没什么好玩的。
While poking around in the Registry trying to fix this issue, I noticed that Thumbnails for AVI files worked, while no others did. The only difference with that extension was this registry key:
在注册表中尝试解决此问题时，我注意到AVI文件的缩略图起作用，而其他缩略图则没有。 与该扩展名的唯一区别是此注册表项：
[HKEY_CLASSES_ROOT\.avi\ShellEx\
{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{c5a40261-cd64-4ccf-84cb-c394da41d590}"
So, I made a registry file with this entry for each extension I wanted thumbnails for. Merged it into the registry and, lo and behold, I have thumbnails again. The file is below.
因此，对于每个我想要缩略图的扩展名，我都使用此条目创建了一个注册表文件。 将其合并到注册表中，瞧，我又有了缩略图。 该文件在下面。
As an aside, while I was trying to fix this, I also picked up a codec pack called the CCCP (Combined Community Codec Pack) and noticed while running through its settings that it had an option to "fix perceived types." I wish I'd known this last week when I fixed THAT problem with missing Media Center Thumbnails.
顺便说一句，虽然我试图解决这个问题，我还捡了一个叫编解码器包CCCP (C ombinedçommunityÇODEC P ACK)，并通过它的设置运行时，它有一个选项，以“修复感知到的类型注意。 ” 我希望上周在我解决缺少Media Center缩略图的问题时就知道了。
Switching over to the CCCP also had the added benefit of letting me watch my MP4 encoded PSP (Playstation Portable) files in Windows Media Player, and added Thumbnails in Explorer for MP4s as well via their settings dialog. Once I got MP4 working I exported those settings and appended to them to this file.
切换到CCCP的另一个好处是，我可以在Windows Media Player中观看我的MP4编码的PSP(Playstation Portable)文件，还可以通过它们的设置对话框在资源管理器中为MP4添加缩略图。 当MP4正常工作后，我将导出这些设置并将其附加到此文件中。
Also, by the way, did you know that thenew location of the Explorer Thumbnail Cache is down here?
另外，顺便说一句，您是否知道资源管理器缩略图缓存的新位置在这里？

Crazy new stuff this Vista, eh?
这个Vista疯狂的新东西，是吗？
