Problems in installing windows update

Hello,
Why I'm always getting Windows 7 update almost everyday?
It's taking so long before I can use my computer because of many updates and after installing updates, it asks me to restart my computer.
What will I do to stop this?
It is really a waste of time because when I shut down my computer, there's like 110 updates to be installed and that's always happening when I shut down my computer.
Please help me.
Thanks.
