Whatever your motivations it is possible to remove inprivate browsing from the new Edge browser in Windows 10.
Employers may want to stop time wasting, parents may be looking to protect children and see who they’ve been spending time with online. Inprivate mode opens up a whole host of potential issues and some may prefer to disable it.
In earlier browsers you would use a group policy to stop this, so far in Edge we have to add a registry key to perform this task.
ALWAYS BACK UP YOUR REGISTRY BEFORE MAKING CHANGES TO IT.
In the run/search box, type regedit and press return.
The registry editor will open.
Navigate through to find the following entry
You will probably need to add MicrosoftEdge and Privacy, if they are there just follow the instructions from that point onwards.
Find Microsoft under Policies, click it once to select it and press the right mouse button. Select new key, type MicrosoftEdge into the name for this key
Right click the MicrosoftEdge key and create a new key named Privacy.
Now select Privacy key and right click and create a new DWORD label the DWORD EnableInPrivateBrowsing and give it a value of 0
Now restart your computer and when you click EnableInPrivateBrowsing in edge nothing will happen.
UPDATE 21/12/2015 thanks to reader JM.
There was a change to windows 10 so if this doesn’t work follow the instructions below…
Create a Main subcategory after this so it reads, HKLM\Software\Policies\Microsoft\MicrosoftEdge\Main
Then add the dword AllowInPrivate to Main and set the value to 0
Restart your computer for this setting to take place and Inprivate will no longer be selectable.
