Q:

How to add an “open in new excel with macros disabled” in windows file explorer context menu? 

I've asked similar questions before, about How to add an “open in new excel” in windows file explorer context menu?  and How to add a "duplicate this folder" in windows file explorer context menu? . 
Similarly, is there an easy way, to add an item to windows explorer's context menu, i.e., when right click on a folder "X", there's a new item "open this in new excel with macros disabled", such that after clicking, the file will be opened not in current excel sessions, but in a new excel window, and the macros will be disabled, i.e. events such as Workbook_Open() won't be triggered? 

A:

Taken from source
Hold down Shift while the workbook is opening.  Unfortunately there is no parameter can be set on a shortcut to disable macro. 
You can also set Disable Macro and set a trusted location so it will automatically disable macros but from files opening from the trusted location.
