The answer here:
TortoiseSVN icons not showing up under Windows 7
Suggests that you might need to modify your windows registry to make the overlay icons display correctly.
I've opened that path in regedit HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ShellIconOverlayIdentifiers
And the following displays.
What is meant to be here if tortiseSVN or similar programs have their overlay icons displaying correctly?
You should have 9 Tortoise related subdirectories below ShellIconOverlayIdentifiers as seen here:
I suggest you re-install Tortoise.
Windows 7 does indeed keep a list of overlays in the register key specified above. The argument for eliminating overlays is actually a valid one, i.e. after a while different applications start fighting each other. There really should be a better solution which allows selected folders to have their own, dominant, overlays. But I can accept that the overhead eventually gets ridiculous.
I checked out my own key. Overlays seem to be loaded in collating order, so various vendors are trying to jump line (say by prefixing their key with multiple spaces). Juvenile. I would suggest deciding which overlays are useful then either deleting or renaming the ones that aren't. (I've renamed Dropbox, making it easier to restore if needed.)
I have the latest TortoiseSVN and the suggestions above didn't work for me.
What worked was putting a z prefix on the keys before TortoiseSVN (hit F2 to rename). This pushed TortoiseSVN to the top when I closed regedit and fixed it.
