我建议向微软投诉图标覆盖限制低得离谱。如果我们有足够多的人抱怨，也许他们会解决这个问题的真正根源:

给微软Windows 7团队关于这个问题的反馈: http://mymfe.microsoft.com/Windows%207/Feedback.aspx?formID=195

Windows只能显示有限数量的覆盖图标(总共15个，在Windows之后有11个)。像Office Groove, Dropbox, Mozy, Carbonite等程序将劫持一堆11种可能的覆盖图标(如果微软增加这些图标的数量，因为使用它们的应用程序的数量似乎越来越多)…

你可以看到设置了哪些覆盖，并在注册表中更改它们(自担风险):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ShellIconOverlayIdentifiers

If you are using TortoiseCVS (and have nothing else using overlay icons), you will get a couple of TortoiseSVN Icons, and all of your TortoiseCVS icons. This is because the overlay icons are used in alphabetical order. Again, at your own risk (editing the registry may blow up your computer, yada, yada, yada -- and if you are reading Stack Overflow and using Windows and haven't edited the registry, you are a rare beast indeed), feel free to rename them (I suggest putting numbers in front of the ones you want to use and "z_"'s prefixed to the ones you don't need). The TortoiseSVN Shell extensions are nicely named so you know what they do, the TortoiseCVS extensions are not. After looking through the source code, I found the pertinent information:

TortoiseCVS0 -在CVS TortoiseCVS1 -不在CVS中 TortoiseCVS3 -冲突 TortoiseCVS4 -在CVS只读 乌龟ecvs5 -忽略 乌龟ecvs6 -新增 TortoiseCVS7 -删除 龟龟ecvs8 -锁定

我在这里(和其他一些地方)尝试了所有的东西，对我有用的(在做了所有这些之后，我认为注册表更改是强制性的)是将图标覆盖\状态缓存的设置从默认更改为Shell，我还检查了“仅在资源管理器中显示覆盖和上下文菜单”。不知道是谁干的，但现在有用了。

如果有人需要64位Windows 7的注册表项，这里有。对我有好处的是删除不经常使用的项目的覆盖:Drop Box，谷歌Drive，微软产品，只保留乌龟的覆盖。这些都是覆盖-没有被删除。

**注意**玩弄注册表会使您的系统不稳定。一定要备份您的注册表。关于备份注册表或注册表设置的各种方法，请参阅谷歌搜索。

记住，这些都是64位的Windows，你应该备份你的注册表

克里斯·埃里克森说得对，给他投票吧。在我的案例中，问题是安装TFS powertools，它添加了资源管理器外壳集成，就像TSVN和TCVS一样。它增加了另外5个叠加。因为它们的前缀是Tfs*，所以它们优先于Tortoise*。我也只是把Tfs的东西加上了z_和TSVN的覆盖回来了。不过不需要重启/注销，只需杀死explorer.exe并重新启动它。

我发现，如果你先安装32位版本，它会把64位版本弄得一团糟。在重新安装windows 7时，我刚刚安装了64位版本，现在看起来工作正常。
