rity updates and other important updates for Windows have been made available, and auto-
matically installs these updates in their latest conditions.

The Pop-up Blocker

In Windows XP, security functions have been strengthened with regard to Web contents.
One of these is the “Pop-up Blocker,” which may prevent some Web pages from being dis-
played.
When web sites requiring the latest Flash Player cannot be displayed correctly on Internet
Explorer , or the Pop-up Blocker may result in many windows being displayed at once, down-
load and install the latest Macromedia Flash Player from the website of Macromedia, Inc..
