Now, open File Explorer and find the folder "C:\Windows\SystemApps\Microsoft.MicrosoftEdge_8wekyb3d8bbwe" and rename that folder to anything you wish. (I normally just append some text to it like "_remove" so I can easily re-enable Edge in the future if I desire.)
Edge should now be "disabled".
Keep in mind that Microsoft may try to re-enable Edge during a future update...
Go to: C:\Windows\SystemApps\
Open folder Microsoft.MicrosoftEdge_8wekyb3d8bbwe

It makes sense to implement these preferences on devices running earlier versions of Windows if those devices should not be upgraded to Windows 10. Obviously, this should not be the only options and a program like GWX Control Panel or manually verifying all updates before they are installed are proper options to make sure nothing slips by.
