Windows 10 Spring Creators Update: The best hidden features

Microsoft's next Windows 10 upgrade, code-named Redstone 4 and informally known as the Spring Creators Update, improves Windows in numerous ways. But Microsoft has also added innumerable under-the-hood adjustments. That's why this roundup exists: to underscore smaller additions you might miss, or explain subtle changes in how Windows 10 works. Unlike previous lists we've compiled, though, some of these hidden features seem tentative, with more work clearly needed. Fortunately, Microsoft seems inclined to keep developing Windows 10, with no major replacement on the radar.
