Windows 7 updates taking a really long time

This is the third time this has happened.

It's 2 updates each time and it takes over and hour for them to finish installing. It always finishes eventually but like I said this is the third time in less than a month that this has happened and I'm wondering if there's a real issue here. This happens on my Thinkpad t61 notebook, I do not have this issue on my netbook at all. The updates on the netbook always finish very quickly.
