Word 2010 Exam login - remove right-click context menu
We're looking to upgrade our Office version in our school from 2003 to 2010.
As part of that I need to recreate the account we use for exams / controlled assessments that restricts use of Spellcheck, Thesaurus, translations etc within Word.
The task is almost complete (ribbon options locked, keyboard shortcuts removed etc) using mainly group policy with the odd thing locked with a mandatory profile. However, there is one problem that persists that I have yet not been able to solve - the right-click context menu within Word.
Ideally I'd like to remove just the "Look up", "Synonyms" and "Translate" options, but as a fallback we can lose the entire context menu if needed (or indeed possible).
I though the solution may lie in the disabling the contextMenu control ID's in the word 2010 Admin Template in Group Policy, but I can't seem to track down the ID's for these functions.
Anyone managed to resolve this problem by any means?
