How to backup windows update

Keep in mind that if you download the updates from the update catalog you will likely end up installing them one by one and rebooting almost every time. A painfully slow process. Downloading SP1 would be a big step in the right direction if you don't have an integrated install disk. That would save you some time on windows update. I also like to download the latest DirectX full version, Silverlight (if you use it), IE 9, Dot Net Framework 4, etc, and save them to a thumbdrive. Microsoft Security Essentials too if you use it.
Another option would be to install Windows, all your drivers, and then hit windows update. Then when its fully patched, save an image of your hard drive with something like Acronis True Image. Then the next time you have to do a re-install just restore the image.

Instead of backing up the updates, you should consider creating an image of your machine that you could use to restore. This will save you lots of work.

Yep...knowing that there's near hundred updates by now....You might like better downloading the SP1 stand-alone installer in two days.

The average joe is not going to have a new standalone installer in 2 days. They are going to have the service pack itself. I guess they can slipstream the SP into the ISO themselves.

Its nice having an integrated SP1 DVD but its not the end of the world if you don't. Installing the standalone full version after a clean install only takes a little more of your time. To me "stand alone full installer" means the full separate down loadable version of just SP1. All the files are there to install SP1 offline with no need for an Internet connection.

I would suggest following pparks1's advice. If you, for some reason, don't want to download updates, then a system image is your best bet.

I dont want any alternative way,
I want download updates which are already installed in my system.

Please suggest me

You already have been suggested the way, using the Download Catalog. However, others have warned you that there are far better methods, and using updates from the Catalog will take MUCH longer than just getting them from Windows Update or using an SP1 installer.

Is your internet connection slow? Is that why you refuse to use better methods? What are you trying to accomplish by making all of this extra work for yourself?
