Windows XP Vs Windows 10

[TygerTung]

"For windows 10, there are more than 200 processes and they commonly use 30-50% of your CPU and disk IO"

Nah.......I'd have 100 processes in the list for sure but current CPU usage is bouncing from 1% to about 6% with Win 10.  It's not bad at all......

It must depend on how fast one's machine is. My wife's laptop seems to get hammered pretty hard by Windows 10. It isn't a high end machine though so maybe it isn't the best for Windows 10.
