Hi Qwinn,

And welcome to the forums.

SafeZone is designed to run separately from Windows desktop. So modifying it could change the safety features built into it by creating a link/hole or a channel to the Windows desktop or system itself if you were to do as you propose. If you are concerned about browser history retention while in SafeZone use either Incognito mode or Private mode (Firefox) instead of the normal default browser that opens first.

Default SafeZone Chrome browser is a hardened browser and does not come with Adobe Flash installed, for example.

What Eddy meant was changing the default settings can bear unforseen consequences but you can change the settings if you wish. But as SafeZone is designed to be closed off from Windows and vice versa, I really do not see the point of opening it up.
