It is advisable to keep your operating-system and software's updated for optimal computer performance and security and Windows allows automatic update functionality to ensure this; however if your computer does not have a functional internet connection getting updates can be a bit tricky and you need to get offline-update files via an internet connected PC and install them on your computer.

Microsoft Windows 7 operating-system supports Windows Update Stand-alone Installer (.msu) which is used for distributing standalone update files for computer's without internet connection, follow the simple trick described ahead to download all updates in a single go.

Downloading Windows 7 Offline Update Files :

1. Microsoft provides .msu files for allowing offline updates.
2. To get .MSU update packages for Windows 7 visit this page.
3. Now, to download all packages in a single go make use of free Firefox extension DownThemAll or a similar batch download link grabber.

4. Copy downloaded .msu update packages to target computer and double-click to install.

Unlike older versions of Windows currently there seems no automated utility to get Windows 7 offline update files but I am pretty sure someone should get it out soon :), if you know of anything capable of this pls. share it in comments below.
