This is the only Windows update that I haven't installed. Everything is running sweetly on my Laptop so what “extra” is the SP going to give me. It's also a potentially big download, I'm on a basic (ie read “slow”) broadband package with Telstra and I try and keep my data traffic to less than 1 GB a month (bet that makes a few of you fall over backwards!) so is it worth my doing and why? I'm using Vista Home Premium.
