We've been helping Adobe to get a sandbox going which is similar to what we used in Office 2010 for Protected View. Their blog post about it is Introducing Adobe Reader Protected Mode. I'm excited that the sandboxing approaches that we've pioneered in Office, starting with a sandbox for our search subsystem, the MOICE sandbox, and finally Protected View is going to be useful in helping protect the customers we have in common with our partners.

It's been interesting working with Adobe – Office and Adobe compete on many fronts, but we put all that aside when it comes to helping protect customers from security issues.
