I have a parent and child account on a Windows 10 box. I want to edit the child's registry to turn off the ability to make web searches from the start menu (I need to add a key to HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows).
If I make that change from the parent account, I'm editing only the parent's values, not the child's. The child account isn't able to run regedit. When I try to open regedit "as administrator" and enter the parent login, HCU is loaded with the parent's registry, not the child's.
I figured the only option was to log into the parent account and use "Load Hive" to pull up the child account NTUSER.dat, but then I get the error "This file is in use", even though that account isn't running.
Is there any way to edit the registry for a non-admin child account?
