Our home PC is older running Windows XP, as well as IE 8 with Outlook Express.

Love Outlook Express!  Our home users all use that still.

But I realize that when our old PC dies soon, we will be getting Windows 8.  I have another personal laptop running Windows 7 and IE 10, so begrudgingly getting used to Live Mail for email on that machine (and getting used to Windows 8 on my new Surface, but it has a useless mail app). 

Seems like I read a lot of problems experienced by XP systems downloading Live Mail.  And in fact, it doesn't list XP as a supported system.  But it would be nice if I could do that on our old PC, because other household users besides myself could get used to it and transfer data, before the machine dies.

Of course, I'm thinking that Live Mail can store information in the cloud, so it's easy to set up a new machine? Is that true, or is information stored only on the machine?

Anyhow, should I try and download it to XP, too much risk to bother with it? 

I have WIn. XP and Windows Live Mail, I want to have a seprate address book for each mailbox, can you help me, Thanks, Neil
I maybe stupid asking this but after using Outlook Express for the past 8 years on my old XP computer i find using Windows Live hotmail on my new Windows 8 machine somewhat baffling at times. I cannot seem to find a way of asking for any new e mails on demand and find myself just having to wait for as and when i get them delivered, any pointers please.
I have installed all the live essential components but the messenger companion add-on is not installed in my IE8 (XP) . What might be the reason ......can anybody help?
I recently upgraded from XP to 7.  Contacts are a problem.  All my old contact groups came over but now they don't seem to work properly.  When I click on contacts they show with thw right addresses in them but when I try to use them, some or all of the addresses are not there.
I have a XP computer that I ran Outlook Express on for a number of years then upgraded to Window Live and Windows Live Mail, all without any problems. I recently bought a new computer and wanted to extract the WLM folders from the XP machine and transplant them on the new Windows 7 machine or at least import them to the new machine.
I can only find the old Outlook Express folders that contain two year only mail. When I look in WLM, tools, option, advanced, maintenance, store Folder, on the XP machine, it gives me a location. When I go to that location it does not exist. How can the program work? Better still where are the folders?
In folder view all the necessary boxes are unchecked giving me full view access to files and folders.
I need to resolve this.

Ever since went from XP to Windows 7, none of my contacts are ever online.  One happens to be my boss who I know for a fact is online every day since this is a faster way to communcate.  They use MSN messenger but Geek Squad told me windows live messenger is the same thing with a different name.  Never once have I seen one of my contacts on line.  Never had this problem when I had MSN Messenger.  Please Advise.
