Evil MS Hotfix
Don't install the Hotfix for KB 912945. It's an optional update that will cause headaches for your Windows users (whether Terminal Server or VM's).
Users will be required to click a dialog box every time they want to run an ActiveX control, even signed ones. Dialog reads "Click to run an Activex control on this web page". Must click multiple times for pages with multiple ActiveX controls. It gets real fun viewing any quicktime movie trailers.
Web pages with the following acitve content will cause this behavior:
- Adobe Reader
- Apple QuickTime Player
- Macromedia Flash
- Microsoft Windows Media Player
- Real Networks RealPlayer
- Sun Java Virtual Machine
