In Windows 8.1 I used to backup my Startscreen settings as follows:

Step 1: Open the Run dialog box by hitting Windows key + R.
Step 2: Type, "%LocalAppData%\Microsoft\Windows" and hit Enter to open
Windows Explorer to the location of the Start screen layout files.
Step 3: Copy the files, "appsFolder.itemdata-ms" and
"appsfolder.itemdata-ms.bak" to your backup folder.

In Windows 10 I find in that same path location only one file:

I suspect this file is a sort of pointer to the real files located in
the c:\Windows.old folder.
Is this correct?
How can I backup the StartScreen settings?

Is there a way to correct that?

thanks in advance, gabriŽl
