也不需要重新启动你的电脑。而是重新启动explorer.exe:

按Ctrl + Shift + Esc。 单击进程选项卡。 右键单击explorer.exe。 选择“结束进程”。 单击“结束进程”按钮。 单击Applications选项卡。 右键单击。 单击“新建任务(运行)”。 “打开”设置为:资源管理器 单击OK。

Windows资源管理器已重新启动，TortoiseSVN图标重新出现。

图标不显示似乎还有另一个原因。 今天我更新了我的TortoiseSVN客户端从1.6。X到1.10.x。之后，我的工作副本的图标不再显示。 但事实证明，这与许多应用程序占据可能的图标无关。原因是工作副本格式太旧了。首先，您必须使用新安装的客户端制作“SVN升级工作副本”。

祝你有愉快的一天

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。

我的主要目的是为TortoiseCVS制作图标。很多建议对我不起作用:卸载，重新安装;通过重命名重新注册;重新启动多次。但是真正起作用的是安装TortoiseSVN。这使得TortoiseCVS的图标起作用。我查了注册表。SVN安装将数字放在图标名称前面:

2TortoiseModified

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.
