Lots of Windows-related news today. Firstly, responding to customer demand, Dell has restarted selling new PCs with Windows XP installed on them. Secondly, Microsoft software will sell for just USD 3 in some parts of the world in an attempt to double the number of global PC users (probably not at all unrelated to this interesting figure). Lastly, Vista may only be three months old in the retail marketplace, but Microsoft is already seeking participants in the beta testing program for the next version of Windows Media Center, codenamed Fiji. Update: Microsoft denied the sales figures in China to News.com.
