Hi, I have the same problem. I made a new Windows XP with the lastest hotfixes, Unattended instalation and some Tweaks. The only new change compare to my old Unattended Windows is the tweak "Disable WBEN Logging". Since I installed my new Windows that was long... (about 45 minutes) when I Logon my session take a lot of time to load the desktop of Windows. Before my Pc load so quickly!!! Sorry for my english
