Today, in all my drives in Windows 7 appeared a red icon. I try to delete the IconCache.db but doesn't work.

Drives with Red Icons in My Desktop

  • Using regedit, what do you have in the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\DriveIcons? – harrymc Jul 10 at 14:14
  • finally is a problem with the last stable version of Dropbox. The @Alex answers works for me. – Víctor Jul 11 at 14:46
  • Take a look at this answer which will also fix the problem. – androizer Jul 12 at 7:57

Update: it's caused by a change in the Windows system by the updates in combination with Dropbox. The Dropbox icon from folders is used on all devices. To fix it whithout deinstalling Dropbox I just removed the overlay icons (which I never bothered about):

Use the RegEdit to go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers

You will see a couple of " DropboxExt0x" entries (01-10 for me). You can export a Backup from the whole "ShellIconOverlayIdentifiers" entry and then delete the Dropbox ones. After a restart the issue is fixed (for now).

    If you could document the specific change to Windows I would be willing to offer a bounty on this answer. – Ramhound Jul 11 at 4:50
  • This works prefectly! Thank you! @Alex – Víctor Jul 11 at 14:18

This is an issue if you are using the latest DropBox version. People fixed this by downgrading it.
