I am planning to buy 'HP - XPS 15 Touch' model laptop, I am windows 7 users and don't know much about windows 8 and i think it is right time to move to windows 8.1, With window xp, 2000 & win 7 we used to buy Professional edition so that it can be hooked domain. Do we have version like home, professional & ultimate edition in windows 8 or something similar.... Does windows 8, 8.1 come in 32 bit version..
Is 32 bit version limited to 4BG of RAM like window 7, xp etc.. or it can support more than 8GB of RAM
