As a consequence of a legal settlement with Sun regarding the Java technology, Microsoft has removed certain products from being available directly from them through any means. Here is an excerpt from their MSDN site:

Products Unavailable due to Java-related Settlement
Some products have been removed from Subscriber Downloads due to the terms of Java-related settlements Microsoft made with Sun Microsystems. These products are no longer available from Microsoft in any form, but may be available through third-party resellers or Web sites.
This list includes large variety of products, including Office 200, Windows 98, Windows XP, Visual Studio 6.0, VSS 6.0d, and many more.
Microsoft suggests you can get these products from various "resellers" - but won't go further than that.
Does anyone know where developers can obtain access to these products (in our case for testing purposes) from inexpensive, reputable resellers? Or better yet, a legal and free resource to get access to the original media if you have an existing, legal license key?
