Portable Update is a windows-base tool for updating a Microsoft Windows computer in a isolated environment.

This is useful in many circumstances:

When the computer reside on a secure lan isolated from internet;
When the computer to update doesn’t have access or can't use a proxy server;
When is necessary to completely update a fresh-formatted computer with the last update before to connect it to network;
When the computer doesn’t have an hardware network connection at all;
When the network connection speed is too low or it is necessary to update the computer very quickly;
In all the other cases when is mandatory to have the complete control on the updating process without connecting the computer to the network.

How it works?

To update an isolated computer, Portable Update use an external cache to store updates.

The cache can reside on any usb external drive or, via private lan network, on a shared path. Once an update is copied to the cache (the only time that an internet connection is required), the same update will be used for all computer that need that particular update.
You'll never download twice the same file to update different computers or for updating many times the same computer. For example, consider that the dimension of one single update can reach and exceed 1 GByte!
Once the update is stored into the cache folder , the program will use standard Windows Update API services to update your computer.
Different updates from different operating systems can reside on the same cache folder because they are individually identified.
As result, you can see the log update in the standard update history log exactly as it was done from the normal Windows Update site!
