I find it is much easier and comfertable to operate with win xp. so i want to know how i should reforamat. i have win xp formating cd.
In hp lap top this win xp to be installed after completely removing win 7
It's not a good idea to put a 10 year old OS on a new or even newish laptop. There's too great a chance some stuff just won't work, like your wifi adapter. Best to just learn the new OS.
One thing i've found a lot of people coming from XP don't like is the new bottom bar/pinning system. Google how to get the old quick launch bar back. There's also tons of tweaks out there on the web getting win 7 to feel more like xp.
Trust me, it's a much better route to tweak win7 then it is to try force xp on that poor laptop.
