I installed Windows 7 64 bit OS in my existing computer which had Win XP 32 bit. My Comcast download speed immediately increased by 45% (from 15.5mb to 22.5mb). Upload speed remained the same at 10mb.
I just put together a second computer with Win 7 (to replace my back up that had also had Win XP) and got the same exact result in increased speed.
All computers were connected by wire to the same router/modem so that is not playing a part in this .
Can anyone tell me why my upload speeds are so much higher with Windows 7 vs Win XP?
