编辑注册表订单对我来说很有用。元素前面已经有#s了。所以它不起作用。 我发现之前的条目有空格。现在我的SVN注册表有了一个空间# name

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

有时候你只需要去TortoiseSVN的“设置”，关闭图标，点击“应用”，再打开。

Windows开始->所有程序->TortoiseSVN->设置

为了完成Johannes的回答，你可以检查这个线程，其中提到了另一个原因(第一个原因是安装32位客户端而不是64位客户端)(强调我的):

只有最新版本的TSVN和TCVS能够共享覆盖图标，并且由于资源管理器有14个覆盖图像和无关的覆盖图标的限制 只是不出现你可能有太多… 如果它的覆盖图标显示，你必须实际使用 32位的Windows资源管理器，这当然意味着你也必须这样做 安装32位版本的TSVN。

在安装TortoiseVCS时可能会出现这个问题，因为:

Looking at what got installed in the filesystem and the registry, it looks like they tried to do what I do with my Shell extensions - install both 64 and 32 -bit versions, so that nobody says "I don't see my overlays/menus"! ;) Unfortunately, it looks like the registry entries for 32-bit got hosed, so the 32-bit extension DLL, even though present, does not have the correct registry entries. If in doubt I suggest to deinstall TCVS and TSVN. Then install TSVN. Maybe after installation reboot twice, not only once. And if they still don't show up go to software control panel and choose to repair the installation. That did the trick for me with when upgrading from the previous to the current version. You should probably install the TortoiseXYZ variant you plan to use mainly first, to improve its chances to fall into one of those limited number of overlay icons slots before the TortoiseXYZ variant you use less. Always keep these limited number of overlay icon slots in mind when trying to analyze malfunctions.

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:

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。
