Back-up Start Settings

Start11 v1

Please use the manual registry export method.

Start11 v2

Available in Start11 v2, is the “Settings backup” area of the configuration menu.

Manual Registry Export

You can manually export the registry to be reimported on any other PC.

Computer\HKEY_CURRENT_USER\SOFTWARE\Stardock\Start8
(Start8 is not a typo, its a carry-over from that version)
Importing would need you to have that export on the other PC (the desktop is fine) and double-click it. It will prompt you that it is about to edit the registry.
Pinned items for all the Start11 menu styles are carried over as well with the exception of the Windows 7 style after a reboot.

For expediency, this batch file will do the export and place it in the current user's Documents folder:

Manual registry export process works with all current versions of Start11/Start10

Windows 7/Modern Start11 Menu Style Shortcuts

For pinned items to be carried over for the Win7 and Modern menu styles, you can copy all the shortcuts located here:

%appdata%\Microsoft\Internet Explorer\Quick Launch\User Pinned\StartMenu
(copy \ paste that into Windows Explorer)

Reboot and it should be as it was for settings.

For any of the exported shortcuts to render on a PC that imported them from another, those apps\folder\documents would need to exist on it and be in the exact same location.
