That does not work on Win10 Home (and I'm not sure even Pro, but I could be wrong about that) because we don't have gpedit.msc available to us. I've tried downloading alternate versions and don't recommend it.
I really, really don't get this frenzy about Cortana. You can entirely neuter the PDA elements of Cortana in a few seconds and have nothing left but a straight Windows Search functionality (but still using a process called Cortana, since Cortana is now what Windows Search is called).
To neuter Cortana back to Windows Search:
1. Open Cortana & Search Settings
a) At a minimum, flip the toggle for "Search Online and include web results" to off. Feel free to flip any other toggles you like to off.
2. Either click the link in Cortana & Search Settings for Other Privacy Settings or just open Settings, Privacy.
3. Take a look at the "Speech, Inking, & Typing" Pane and make sure that the "Getting to know you" feature is off. I cannot remember what it looks like when it's on because I turned it off ages ago. If it's off the button under the "Getting to know you" section will read "Get to know me."
4. Optional, and not directly Cortana related, go through each and every Pane of the Privacy settings and set the toggles to your preferences. This takes all of 5 to 10 minutes, particularly if you're an "all on or all off" sort of individual. It will take a little longer if you want to allow specific things access and other things not.
Then, if having the full Cortana search box on your taskbar annoys you then right click on the taskbar to get its context menu to come up, choose the Search item, and choose either "Show search icon" (which will cause a button with a magnifying glass to be displayed which you have to hit before entering search term[s]) or "Hidden."
The Personal Digital Assistant feature of Cortana is very easy to turn off and you can end up with functionality that was pretty much what old Windows Search was. Cortana is no more malware than Command Prompt is.
All of the above is on Windows 10 Home 64-bit.
