The biggest flaw or bug in Windows 7 in my opinion was the frequency of Blue Screen Of Death when a USB device was unplugged without ejecting it from Windows. It was like if someone using Windows XP would come to me and I plugged in his USB drive in my laptop and then he would hurriedly unplug his USB drive without knowing that it would crash my Windows 7.
