可以下载最新版本TortoiseOverlays。其所用的解决方案与下述类似：使用了在注册表中相关条目前加数字的方法。
原因：
Windows can only show a limited number of Overlay Icons (15 total, 11 after what Windows uses). Programs likeOffice
Groove,Dropbox,Mozy,Carbonite,
etc, will hijack a bunch of the 11 possible overlay icons (boy would it be nice if Microsoft upped the number of these as the number of applications that use them seem to increase and increase)...
解决方案
You can see what overlays are set up, and change them (at your own risk) in the registry here:
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 ofTortoiseSVN 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 - In CVS
- TortoiseCVS1 - Not in CVS
- TortoiseCVS3 - Conflicted
- TortoiseCVS4 - In CVS readonly
- TortoiseCVS5 - Ignored
- TortoiseCVS6 - Added
- TortoiseCVS7 - Deleted
- TortoiseCVS8 - Locked
