I use Windows XP professional, and ever since I followed the "upgrade", or rather downgrade, to outlook.com email, the program works very slowly, clumsily, and even slows down other programs and the computer in general.  Is it the ads of the free program that impede performance, or poor application design, or neglect of XP platforms?

Is there any fix, or is the only solution to leave this poor email prograqm?
