The easiest way to backup and restore Fences settings is via the snapshot system. Simply copy the snapshots from one machine to the other, then restore the snapshot:
Snapshots are stored in the following directories:
C:\Users\USERNAME\AppData\Roaming\Stardock\Fences\Backups
You will need to replace USERNAME with your user account name on your PC.
Alternatively, you can import the following registry key into the new machine's registry:
HKEY_CURRENT_USER\Software\Stardock\Fences
To restore a snapshot:
-Right click on the desktop and select "Configure Fences..."
-Click on "Layout and snapping" on the left hand side of the configuration window that appears.
-Select a snapshot you wish to revert to. A preview window will appear showing you what the desktop will look like.
-Click Restore Snapshot to revert the desktop to this preview.
