Microsoft has announced a gift for any Windows types wanting to do a little self-improvement: the release of the company's biggest ever collection of electronic books, all of which are available to download completely free of charge.

Microsoft founder and Chairman Bill Gates has made an appearance in the latest video for Windows 8.

The company is rolling out the big guns to promote the new OS and the video goes on to cover Surface, the cloud and as Steve Ballmer dubbed it, ‘The new era of Microsoft’, the era of devices and services.

Older and wiser, it’s interesting to see Gates chatting in a relaxed environment and to find out what he uses himself when it comes to MS products.
