My Overlay Icons is Missing

0. Test Environment

Windows 8 Enterprise English 64bit

1. Why?

Windows can only show a limited number of Overlay Icons (15 total, 11 after what Windows uses).

Programs like Office Groove, Dropbox, Mozy, Carbonite, Kuaipan, TortoiseSVN, etc, will hijack a bunch of the 11 possible overlay icons.

2. Steps

You can see what overlays are set up, and change them in the registry here:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ShellIconOverlayIdentifiers

So, you can re-sort them by rename these items. Just putting numbers in front of the ones you want to use and "z_"'s prefixed to the ones you don't need.
