I stumbled upon a rather interesting feature while messing around with the Office 2010 Technical Preview. Its called Protected View which kicks in automatically when you open a document that came from an outside source, like the Internet. A good measure I must say, which would protect your system from malicious content.
You can still view the document while in Protected View, like I was able to run the presentation in full screen. You canâ€™t obviously edit the documents because they are locked for editing. To enable editing, you have to â€œindicateâ€ that you trust the source by clicking the Enable Editing button from the info bar or the Backstage view.
Iâ€™ll continue to post more interesting stuff I find about Microsoft Office 2010 Beta. In the mean time you can read about other new features of Office 2010 that I have already posted, or subscribe to the blog for more updates.
