2. Not being able to change background lockscreen image.
Your windows 10 might not allow you to change your lockscreen background picture. You get to set your background picture a number of times and suddenly you notice it doesnt seem to work anymore. I have being stuck with the same lockscreen image for over a year now. Still cant seem to get around the problem.
3. Poor trackpad integration by OEM's
This might probably not be a major issue, but it definitely is an issue when you cant seem to take full advantage of your trackpad gestures. Trackpad gestures make flipping and navigation much easier without hassles, just like we have in the macOS. However, I wouldn't largely blame microsoft for this, even though I think they can do better with better with providing better software management of trackpads OEM's can make us of for better integration of trackpad gestures.
