Windows 8.1 Update 1 Changes:
- Apps purchased from the Windows App store can be pinned to the taskbar
- Cursor gestures now have a small delay before triggering
- Power and Search buttons have been added to the Start screen
- Right-clicking a Live tile spawns an actual right-click menu rather than showing charms
- Windows Apps can be closed and minimized with the mouse
- You can now boot directly to the desktop
I'm not a huge fan of the Metro/Desktop hybrid that Microsoft seems to be pushing with Windows 8, but I will say that Windows 8.1 Update 1 includes enough small changes that I no longer hate the interface. I'm only slightly annoyed now.
