T Moore. Yes, it is Windows 10 and yes, I did make sure to go into Settings first to "Sync your settings" i.e. all the toggles were switched to on before going on to set up the in laws PC. I even, after setting it all up, tried the famous "turn off and turn it back on". Interestingly, on my mother in laws, I was told to wait while Windows was getting things ready but the only thing that really synced was the background photo. In my father in law's profile, passwords were saved. But that was the extent of the sync.

paragoneer. I am not too sure but I presume so as there is a toggle option under Sync your settings for all "Other Windows settings". To me, the Start menu would fall under that category.
I did some reading both before an after setting up the PC to try. This seems to be a long term ongoing issue. I doubt very much it relates to your Aussie internet!
