How do i install updates

Some updates need to be installed separately, the system restarted, and then more updates are being downloaded and installed.

You can always open the "Windows Update" from Start Menu, or alternatively open Internet Explorer and choose Tools -> Windows Update, and do what the site tells you to. You will see all the updates available and still needing to be installed, and also information if a given update needs to be installed separately.

Good luck :)
