During this generation, Microsoft increased focus on building stronger connectivity between Xbox consoles and Windows devices with an increase in video games that connected to the Xbox Live service and supported Xbox Achievements and Xbox Friends. This initiative began in earnest with Windows 8 PCs and Windows phones and evolved even further when a dedicated Xbox app replaced the SmartGlass app and the launch of Windows 10 (and the now defunct Windows 10 Mobile) which refined the connectivity even further and introduced Xbox Play Anywhere, the ability for crossplay and cross-buy between Xbox One consoles and Windows 10 devices.
Two significant redesigns were released after the Xbox One’s launch. The Xbox One S was slightly more powerful than the original Xbox One and supported HDR gaming and 4K media streaming (not 4K gaming). An All-Digital Edition (with no disc drive) version was released, as was one with a 4K Blu-ray disc drive. The Xbox One X console was much more powerful and supported HDR and 4K gaming and featured a 4K Blu-ray disc drive and support for 4K media streaming.
