So they decided to make
a few changes to Windows 10 for the anniversary update. It's like they're using their datamining to find things people do the most with Windows 10, then take it away from the Home and Pro users.
In a nutshell:
Cortana can no longer be turned off.
The ability to turn off various Policies has been removed with a note it's "only for Enterprise and Education editions". Policies such as the Microsoft Consumer Experience (Probably so they can start advertising stuff in here later on), Show Windows Tips (Probably to start suggesting you buy stuff to do what you need to do), Do not display the lock screen (You know, where ads are currently shown iirc), and Disable all apps from the Windows Store.
The policy manager thing as a whole is yanked from Home users as well - they figured that out last week when they found Cortana could no longer be turned off and the button to conveniently turn it off that was in the start menu had disappeared. Now, I believe you CAN turn Cortana off still, at least for now, but it's just no longer easy to do. They took the button away, policy manager is gone for the bulk of users as well, but you can still do it the old risk-bricking-your-system editing the registry.
