How to use

Four steps:

  1. Search target computer for new updates
  2. Download updates needed to the target computer. This can be done from the same target computer if connected to internet or on any other computer connected.
  3. Search again the target computer. This is needed because it is only during the Search Phase that updates are physically copied to the "Software Distribution" directory.
  4. Install all updates of your choice.

Under the Hood of PortableUpdate

PortableUpdate update every internet unplugged computer by means of two steps:

  1. Copy the update from the external cache (that is from the USB drive) to the Windows update's internal cache (Software Distribution).
  2. Invoke the Windows Update's Install procedure providing the copied update as parameter.

The external cache will be filled only once per update session using the same tool on another computer connected to internet.

  • Once downloaded the updates needed from the Windows® Update site to the PortableUpdate cache, they remain here ready for every computer that needs that update in the future or for the same computer if you need to install it again.

Thus, the complete algorithm is condensed in two phases:

The "Unplugged" Phase

  1. Scan the unplugged computer to take note of all updates that are needed; this is accomplished using the standard Windows Update Agent API.
  2. If the update are already present in the PortableUpdate cache, fill the internal Windows Update cache (this pass is possible only during the scan phase);
  3. Install one, two or all update copied in the previous step.

The "Plugged" Phase

  1. Download from the Windows® Update site all the update needed to all computer searched in the "Unplugged" Phase to filling the PortableUpdate cache;
  2. Go back to the start of the "Unplugged" Phase.

How to Install

You may download the most recent version of PortableUpdate here.

As other Portable Windows applications, PortableUpdate doesn't need any setup phase, so once properly installed, it is ready to be run instantly from any computer.

  • From Wikipedia: (..)In order to make properly portable applications, software applications must leave the computer they run on exactly as they found it when finished. This means that the application cannot use the registry, nor store its files anywhere on the machine other than in the application's installation directory.(..)

The very first time, PortableUpdate need to be run from a computer connected to internet to download all the files and information it needs for run unplugged.

The USB Disk capacity

Few recommendations:

  • before installing, take a look on the USB hard disk free capacity, because the cache directory can grow very quickly;
    • Practically speaking, consider an USB disk with at least 15 GB of free space;
    • However, space needed depend from how many different OS and how many languages you want update;
    • PortableUpdate can download the same update for different os and different languages and it will never delete from cache any old or superseded update;
    • If you use, instead, a network share, of course you don't need to worry about free space (it depends from your network share capacity);
  • copy the program in a folder on your USB drive, if possible near the root;
  • run the program the very first time while the computer is connected to internet: PortableUpdate automatically create all directories and download all data needed to update any unplugged Microsoft Windows® client;
