Got me a Vaio computer about half a year ago. The problem, apart from all bloatware (where is Sony's "Fresh start"?), the Windows 7 had some issues with the super mega advanced key combo: alt+tab. Each time I used it the pop-up menu flickered. I didn't do much about it since I was using my still going strong old one for much of my daily work. But then...
Yesterday, al+tab on my desktop computer started flicker too. Each time... flicking Windows 7! I did some searching and found one here (thanks embram). The solution: righ-click on desktop > Personalize > Windows Classic > (wait for loading) > (back to?) Windows 7 Basic > (wait for loading) > done.
