Persistent Flash shared objects are making the news again. Here's a script for Windows that removes them without having to visit the "Settings Manager".

Microsoft's new Silverlight technology is aimed at unseating Flash as the platform of choice for delivering rich web content. Take a look at the Privacy Policy however and you will see something to please web advertisers and those who wish to track user's browsing habits.

Standard computer information typically includes information such as your IP address, operating system version, browser version, your hardware ID which indicates the device manufacturer, device name, and version, application version and your regional and language settings.
