Well, the referral comes when I press S1 and try to do it there, so I guess you're right and Sony are handing over to Windows, though the Sony menu item is as I say, about temperature control.
Last night. 176 updates (after SP1 three days ago) and this morning it said they'd failed. It then spent an hour going back and then installing 50-ish of them. Running now, but since I'm told Sony are now out of the laptop market*, this all seems a waste of time.
*a local dealer on Saturday. I was unaware of this.
