Lori, Home users don't ordinarily need Windows XP Pro. In addition, if you upgrade your JFW to Pro, not only will you have to pay more now, but you will have to pay more every time you purchase an SMA. If you should upgrade to Windows 7 in the future, be sure to get Windows 7 Home Premium for the same reason.

I did and was told I could iether downgrade my system to windows XP Home adition, or else upgrade my JAWs to 12, which would work fine with Windows Profferssional. The problem is it'd cost me about £300.38. Does anyone else use JAWS with Windows XP Proffessional, and if so is it worth the upgrade? I don't know whether to just go for the upgrade and pay the extra money or whether to get a more basic version of XP. I'd be grateful for any advice on this before I make a choice. Many thanks from Lori duncan.
