Again, the answer to that question is, unfortunately, no. After sharing this information, I'm usually asked whether Microsoft ever unlocked the settings for the Bubbles, Ribbons, and Mystify screen savers it introduced in Windows Vista. Windows 10 includes the same set of screen savers that came with Windows Vista. Unfortunately, the answer to that question is no. The second thing people ask is whether Windows 10 comes with any new screen savers. It's just not readily apparent because Microsoft buried the Screen Saver Settings control on the Lock Screen tab in the Personalization settings page.
In fact, I have had several people ask me if Windows 10 even comes with screen savers. However, screen savers still have a cool factor that appeals to some computer users.
And with today's LCD monitors most people use the energy-saving settings to put the display in sleep mode rather than run a screen saver. Screen savers are not all that important anymore, now that CRT monitors are basically a thing of the past.
