Windows 7

Upgrade to win 7 from win vista really took so much time
from 2:30 pm till 11 pm
-_-
nothing special i think...
my pc still the same

update:
last night i turn on real temp
and this morning... i get a maximum temperature of
86 83 85 84 (all in celcius)
at 2:35am

how could this happen?
86C is when I run Prime95, yet... when my win 7 idle at night
the temperature rise up till that point

vista minimum
38 celcius
vista idle
40 - 45 celcius
vista load (normal)
55 - 61 celcius

win 7 minimum
52 celcius
win7 idle
58 - 62 celcius
win7 load (normal)
haven't try yet

i even clean my heatsink just for win 7
yet, the temperature rose up... i wonder why...

my advice.. DO NOT upgrade windows vista to windows 7
but DO install a FRESH installation of windows 7
upgrade from vista not only waste time
but also will bring the bad luck to 7
T_T

(will lost around 700 of my program if i install fresh)
