Most notably, a lock screen greets you as soon as you boot your PC, which has to be clicked or swiped away before you can log into Windows. Unfortunately, there are still a few minor remnants of Windows 8's touchscreen-first approach. Where it once required awkward gestures to access key features, Windows now recognizes when you're using a traditional desktop or laptop, then responds by making sure that all features can be easily discovered with clickable buttons and menu entries. If your PC setup includes a mouse and keyboard, you'll be happy to know that most of the touchscreen-first features of Windows 8 have gone by the wayside in Windows 10.
