Thank you, hornet72 and Busykid508. I've installed win7 pro in my pink S10 work perfectly and run faster than previous win xp HE. tips: -uninstall all 6 t0 4 adapters (i got 231 adapters in 6 months) in device manager you'll get fast booting and perfomance -run CMD as administrator type "netsh wlan stop hostednetwork" than reboot.
