| Can a Windows update actually be a downgrade?
| Yes, and Microsoft performed one last week, when it released its
| latest Windows update, MS06-013. Along with the code to fix various
| security holes in Internet Explorer, Microsoft included a patch to
| handle what is commonly known as the Eolas patent problem. This patch
| changes the way web browsers interact with ActiveX controls, and could
| affect things such as Macromedia Flash, Apple QuickTime, Adobe Reader
| and various applications that run in a browser.
