The Windows Club uses Google AdSense, etc, for display ads. Such revenue goes towards the hosting & upkeep costs of the website, development of freeware, payment to authors, CDN, Cloudflare, etc, apart from also being a source of revenue for me.

Nothing on this planet is free. Many of us assume that the Internet is a free source of information. Is it really free? Can it really exist in the utopian free state? In today’s life, one cannot do away with ads – whether it’s in the newspapers, the television, the outdoors or the web.

The ads are there, you may choose to ignore them – but they are still there none the less, make no mistake!
