Hello!
All those people who have a blanke page when clicking on the Microsoft Update page or nothing appears in the Yahoo Messenger if typing a message, try the following:
1. Reinstall the Visual Basic Script Support
it can be found here:

if your OS have a different language, choose that type of Visual Basic Script Support.
2. Reboot the PC
Should help and work.
Waiting for your feedback.
