Windows Live™ Messenger, also known as MSN Messenger 8.0, the version number I'm referring to here is Build 8.0.0566. After this upgrade, compared to the 32XX version, the interface has become much less appealing, especially with the color scheme changing to transparent colors, which looks very unpleasant. I've tried N kinds of color settings, and none of them are satisfactory. To check the version number, you can look it up under Help -> About. After my own testing, the following ad-removal method is effective. The information comes from the Internet.
