I see Windows 10 as a part of the continuing evolution of Windows - it's not a million miles away from Windows XP, but I wouldn't want it to be.

Some new features:

- Cortana (I don't use it, but I know lots of people that do)

- The Windows Store and UWP apps

- High DPI support (this is something MS does very well compared to Linux desktops)

- Windows Hello (I find this really for signing in with a fingerprint)

- BitLocker (this is a bit one, IMO)

- Device Guard (Enterprise only, AFAIK. Very usual in certin environments)

- Windows Defender (it's now a 1st class AV - I have no reason to use anything else)

- Window Defender Exploit Guard

- Windows Defender Credential Guard

- Windows Defender ATP (only for large enterprises, but it's amazing)

- Windows S mode (this is a pretty big deal, and it's suitable for a lot of consumers, even if it's not exactly HN users' target market)

- Improved VPN support

- Built-in snipping tool (WIN + SHIFT + S)

- Dark mode (I like this)

- Improved Start Menu (IMO)

- Task switcher

- Action centre

- Improved command prompt (even supports copying with CTRL-C, how incredible!)

- Edge (OK, maybe moot now)

- Multiple desktops (yes, I know these have been a feature of Linux window systems for decades)

I imagine I've left out quite a bit too.
