Mark Wilson writes: We've all become used to the idea of ads online — it's something that has become part and parcel of using the internet — but in Windows? If you've updated to build 10565 of Windows 10, you're in for something of a surprise: the Start menu is now being used to display ads. We're not talking about ads for Viagra, porn, or anything like that, but ads for apps. Of course, Microsoft is not describing them as ads; 'Suggested apps' has a much more approachable and fluffy feel to it. Maybe. This is a 'feature' that's currently only being shown to Windows Insiders, but it could spread to everyone else. Will it be well-received?
