There have been a lot of other lesser changes in Windows 10. The Taskbar now runs on the Start screen when you're in tablet mode, which helps to unify the tablet and non-tablet interfaces. It's now black, which makes the icons on it stand out more clearly.
File Explorer has seen changes as well. Its icons are more colorful and brighter. You can pin and unpin folders to it on the Start menu. You also get to OneDrive from inside File Explorer; it appears as a folder with subfolders underneath it. And you can share files -- click a file and select Share from the top menu and you get a variety of ways for sharing, including via email and Twitter. You can compress a file and burn it to disc from the same menu.
The Windows Store has also gotten a makeover. The design is simpler, cleaner, even elegant. More important than that, though, is that you can now download and install desktop apps from it, something not previously possible. Microsoft is also making a push to get more apps into the store by introducing what it calls Universal apps that will be able to run on any Windows device, including desktops, laptops, tablets and phones.
Also new is Task View and the ability to create multiple desktops. Tap the small icon just to the right of the Cortana search bar and you'll see all of your currently running apps and applications as thumbnails on the desktop. Click the X on any of the thumbnails to close it.
More importantly, though, you can create multiple desktops, each with different apps and applications running on them. To do that, when you're in Task View, you click New desktop to create a second desktop; you can then run apps and applications inside it. In fact, you can create several desktops; to switch among them, click the Task View icon, and then click the desktop you want to switch to.
If you've got the proper hardware, Windows 10 supports a biometric security feature that Microsoft calls Windows Hello, letting you log into Windows via a fingerprint scan, face scan or iris scan.
Not everything about Windows 10 is an improvement over Windows 8, though. Whether you like it or not, Windows 10 updates are always automatically installed. In Windows 8 you could pick and choose which updates to install. Not so with Windows 10. What Microsoft sends via Windows Updates gets installed. Case closed.
The bottom line
It's this simple: Windows 10 is a dramatic improvement over Windows 8. It works as single, unified operating system rather than a Rube Goldberg kludge of two operating systems poorly bolted together. It changes its interface depending on whether you're on a tablet or a traditional PC, and runs well on both.
