Originally caving under pressure from Adobe, Microsoft pulled the stock support for saving a file as a PDF in Office 2007. Adobe went so far as to make the issue
a legal one. However, they still promised the end user that a downloadable module for Office would be made available. This caused a bit of controversy, but Microsoft has made good on their promise, and is now making available
the module, along with two additional ones for XPS and XPS + PDF support. XPS is a bone of contention with Adobe, as it seeks to compete with PDF, so MIcrosoft has made it an optional component for Office that OEM's can remove. The modules can each be retrieved from Microsoft's download center
, though it has precious little use to those not participating in the Betas as Office 2007 is still a ways out.
