Windows 10 loses customisations after reboot

Hi fellow Win 10 users
My wife and I both have exactly the same computer - HP Touchsmart 620 - upgraded from Win 7. Our preferences include hiding the Language/Keyboard icon by customising the Taskbar & Start Menu options, and also turning off the touch screen function which now in Win 10 we can only do by disabling HID Compliant Touch Screen through device manager. Here's the thing, my customisations stay, but my wife's default back to showing the language bar and activating the touch screen after every reboot, even though the HID Compliant Touch Screen is still disabled in Device Manager. Would anybody like to comment/suggest anything to overcome this issue?
Cheers

Hi, a wild guess- you could try resetting permissions in the registry.

Often this sort of thing may be also 'resolved' by creating a new user profile. However, that can be a lot of work. What you could do is create a new profile on your wife's PC just to see if the symptoms are still present. You can always remove it afterwards.
