If your laptop like mine is part of a domain, then updates are likely to be controlled by your IT Team. In our office, our IT team uses WSUS to download the updates locally, test them on local machines and then approve the updates for general consumption across the organization. I am one of the few in the office to use Windows Vista, so these updates are approved at the last and I have to wait. More so, ultimate extras don’t flow correctly through WSUS. Since they are controlled by WSUS, even if I am a local system administrator I cannot directly run Windows Update locally or go to Microsoft Update and get updates.
This week one of my IT Engineer gave me a tip. It was to login locally to the machine, using a local machine user name and then use Windows Update. I used it and it worked perfectly. Please be warned that doing updates this way, may not be supported by your IT Team!
