as I said.. no updates pending.. and no reboot pending. couldn't get back on to check his SP level though
If you have a Windows 7 machine at home you should be able to download and save the 54 MB installation file to your computer and put a copy on a thumb drive to take to work. You don't have to install it on your machine.
The 54 MB file is a setup utility type file since after it is run additional files are downloaded to the pc to make everything work.
Do you have any type of firewall or AV program at work that could be blocking the download?
