I finally found again the MS web site that checks to see if one's computer can be upgraded to WinXP. Here it is: http://www.microsoft.com/windowsxp/home/upgrading/advisor.mspx Even if it does say that a 4+ year old computer can be upgraded to WinXP, problems with the old hardware and firmware can pop up.

Also will it affect the modem I have for broadband? How much memory does one need for XP? Not a computer geek as you can tell. Thanks in advance. Joan/Ohio
