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:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers]
1TortoiseNormal
2TortoiseModified
3TortoiseConflict
4TortoiseLocked
5TortoiseReadOnly
6TortoiseDeleted
7TortoiseAdded
8TortoiseIgnored
9TortoiseUnversioned
Groove Explorer Icon Overlay 1 (GFS Unread Stub)
Groove Explorer Icon Overlay 2 (GFS Stub)
Groove Explorer Icon Overlay 2.5 (GFS Unread Folder)
Groove Explorer Icon Overlay 3 (GFS Folder)
Groove Explorer Icon Overlay 4 (GFS Unread Mark)
SharingPrivate
TortoiseAdded
TortoiseConflict
TortoiseDeleted
TortoiseIgnored
TortoiseLocked
TortoiseModified
TortoiseNormal
TortoiseReadOnly
TortoiseUnversioned
zEnhancedStorageShell
zOffline Files
zSkyDrivePro1 (ErrorConflict)
zSkyDrivePro2 (SyncInProgress)
zSkyDrivePro3 (InSync)

如果你想在Windows 7 64位的32位应用程序中使用Tortoise，你需要同时安装64位和32位版本的Tortoise。据乌龟的制造商说，这工作得很好。(源)

我的偶像也消失了。注册表修复对我也不起作用。

我是这样把它们找回来的:

安装最新版本的tortoiseoverlay 重启资源管理器

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。

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

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。
