Service Pack 3 for XP automatically installed itself on my PC a couple of weeks ago, and completely trashed my PC - no mouse, internet, CD drives or USB ports. After much messing about I've managed to get the mouse and CD drives back, but still no internet or USBs. I've spent a lot of time on the phone to Microsoft Helpdesk, who have tried to be helpful (while denying that the failure of the internet could be anything to do with the software) but who have on several occasions failed to call me at the promised time. I'm expecting a call this evening, and also expecting that the remedy will be a complete re-install of the OS. Needless to say, I'm not impressed.

If some spotty youth had hacked in and made my PC unusable it would be a criminal offence. Why is Microsoft any different?
