Windows 10 Disable 'type to search' on start menu (Cortana)

[BSchwarz]

Hi, i hope you can help.
I have been trying all day to suss this and i just cannot for the life of me get this to work.
I work in a school and our students cannot/should not have access to search app's on the start menu. Firstly, can we disable apps from being searched on the start menu? (attached a screenshot below)

So far i have

1. Disabled the search 'box' on the task bar
2. Disabled cortana via GPO - Even though this does nothing from what i can tell.
3. Added a disallowed file rule in the path of cortana within c:\windows\systemapps - This works! However when a user logs in, the start menu is not clickable for the first time a user clicks the bottom left button. Although if the user closes the start menu and re-opens it. The start menu works totally fine. Another screenshot here to show the start menu greyed out: https://imgur.com/7MZZVmO

In short, all i would like to do is remove APPS from the start menu! or un-grey out the screen when a user logs on.
Thanks,

Joe.
