7 Days: A week of Windows 10 updates, Insta-groan and artificial horizons

The weekend is upon us once again (woohoo!), and after another week packed with updates, announcements, rumors and insights, its arrival is certainly welcome. And as ever, 7 Days is here too, to walk you through what's been happening and bring you up to speed. We begin our odyssey this week in the UK, where the European Commission has blocked Three's proposed 10.25 billion acquisition of O2 UK, which would have created the country's largest mobile network operator. The EC determined that the deal would harm innovation, limit competition, and increase prices across the market. Cloud CRM platform Salesforce suffered an outage earlier this week affecting a relatively small proportion of its customers.
