When launching windows 8

"....currently i m using 7 ultimate and its working awesome." !!!

--> I wouldn't be too quick to 'upgrade' just yet - do a little more research on Win8 1st, especialy the view in Tom's forums and other reputable.
 

Or he could form his own opinion instead of some one else's. But if Windows 7 is working awesome so will Windows 8 with out a doubt.
