Microsoft released SP1 for some time ago, but now it seems that the M$ guys are working on SP2. I found a lot of hotfixes on their FTP server. Some of the files are already available at WindowsUpdate. More will be available there soon as we know M$. Downloading this small fixes is useless because they are password protected.

Go here to M$ WinXP SP2 FTP directory: M$ FTP.
