I developped a small soft wich can install downloaded updates automatically
by chaining them.
First, it scans the registry to check if the update is not installed, then it installs the update
It uses [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall]
And only check The KB# updates
For the moment, this soft don't use "Silence" mode to install the updates and needs confirmations of the operator
You can choose English or French languages, and you have only to indicate the Windows Update Dowloader files location
You can find The Windows installation program here (tested on Windows XP SP2, sorry the install program is in french!!)
You can find Visual Basic 6 Sources here
Sorry for my broken english...
