I have just downloaded the beta products from the windows live. But when I start to use this I have found that I was not able to sync along with my windows XP, it started to modify my mind. Can I have live sync on my windows 7 laptop, and have it work with live sync on my windows XP pc? Or am I able to have both the versions of sync working at the same time on my windows 7 laptop? So regarding this if you have any solution then please help me.
