My little U1 is getting slower and slower so I wanted to make a fresh install, but I have a problem, I lost my Panasonic Recovery DVD, so I have the COA but I can't install window 7 again.

Can you help me out?
Thanks.
Yes, It came with Windows XP from factory. Doesn't anybody know where I could get the iso? I don't think is legally wrong to share the DVD as long as I use my serial number.Unsupported Product
