there are many limitations,as well asmanyfacilities are not available in windows xp home editionso IS IT FASTER THAN PROFESSIONAL EDITION?????????????????????????????

Strange that you should ask this question in a forum that focuses on Security, Privacy and User Accounts for Windows 7. What does speed have to do with Security or Privacy? What about asking the experts in a Windows XP forum? Anyway, the answer will most likely be "No", i.e. no difference in speed.

thank you for your suggestion ,next time i ask the windows xp related questions in windows xp forum.
