Here's a power tip from the tip master, Jeremy Hurren. In this gem, Jeremy shows you a quick way to make it easier to view sublayer information.
If you're a power user who needs to manipulate the information in your layers directly, you may find this useful.
Currently you may be using regedit to look at all the keys under HKLM\SYSTEM\Altiris\FSL to find which two areas match your layer.
Modify This Key
HKEY_LOCAL_MACHINE\SYSTEM\Altiris\SVS Flags (DWORD) = 0x00000001
In the details view, you'll get an extra column of data showing "Sublayer Info" letting you know where to find your layer data.
For more information about modifying values in the FSL key, see the tip Auto-Closing Applications Running from a Layer.
