How to Disable Protected View from Registry for Office 2010

Disable Protected View from Registry

Like most options in Windows there is a way to disable these settings via the registry too. If for some reason the options in Office do not work or you want to be able to automate this setting for multiple computers you can try setting one or more of these registry values below.

HKCU\Software\Microsoft\Office\14.0\Word\Security\ProtectedView

HKCU\Software\Microsoft\Office\14.0\Excel\Security\ProtectedView

HKCU\Software\Microsoft\Office\14.0\PowerPoint\Security\ProtectedView

The three values you would want to set are:

DisableAttachementsInPV

DisableInternetFilesInPV

DisableUnsafeLocationsInPV

By setting each value to 1 you will disable Protected View for that file location.
