Better than all of them.
* improved file copy dialog, including pausing
* much faster boot
* improved task manager (as you said)
* better multi-monitor support (I have 2 monitors)
It's not much but was worth the $30 upgrade. I don't mind the new start screen but I understand that is subjective.Granted I haven't looked into it fully but I doubt the actual cold boot speeds vary wildly between the two.
I know my SSD-based Windows 7 system could boot to the desktop in less than 10 seconds when it was new, but now that it's over a year old with dozens of additional installed programs and drivers, I'm lucky to see the desktop in less than 30 seconds.
- lighter memory usage
- better power management
- address space randomization (forcible)
- full hardware (direct-x) rendered UI
- storage spaces
- hyper-v
- incremental file histories
- mandatory DEP
- system refresh
Of course, at the UI level, there are various changes that are a mix of good and bad IMHO, but overall, I would say more parts of the UI suck a little less than before.
