SafeGuard overlay icons are not displayed in Windows Explorer

  • ID de l'article 108784

Issue
SafeGuard overlay icons (key symbols) are not shown in Windows Explorer.

Known to apply to the following Sophos product(s) and version(s)

SafeGuard LAN Crypt Client for PC
SafeGuard File Share
SafeGuard Device Encryption
SafeGuard Data Exchange
SafeGuard Cloud Storage

Cause

There are 12 available overlay icon slots in Windows which can be used by 3rd party applications. If this number is exceeded, the overlay icons applied most recently are not shown. This is a limitation of the Windows operating system.

What To Do

You can check and modify the overlay icon slots in the registry of the client. They can be seen in the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers

Here is an example of a computer that only has SafeGuard Enterprise installed, all overlay icons will be displayed correctly:



Here is an example where the limit is exceeded by three, the last overlay icons will not be shown (in this case these are the icons required for the volume-based encryption status: SgnIconOvl, SgnIconOvl2, ...):



If you want to have the SafeGuard icons displayed, you need to uninstall the other 3rd party applications (in this case TortoiseSVN) or rename the corresponding keys. Windows evaluates this list in alphabetic order so the icons you want to have shown must be within the first 12.
