If the running version of WUA is too old or if WUA isn't running at all, install the most recent version of WUA (or at least a current version of WUA).
Introduction Key benefits of using SUS to deploy Windows XP SP2 Situation overview Factors to consider when using SUS to deploy Windows XP SP2 Overall recommendations Summary Windows XP Service Pack 2 (SP2) contains major security improvements designed to provide better protection against hackers, viruses, and worms.
When necessary, to ensure that users have the latest WUA, prompt them to install KB949104 or the latest WUA.
Follow these steps in your app to determine whether or not the running version of WUA is the most recent one (or at least a current one).
But even if you know the version of WUA is out of date, you can't use the WUA API to force a self-update.
Additionally, if Windows Update on the computer is in such a state that automatic self-updates are failing, you can't use the WUA API to recover from that state.
You can use this installation package to install the latest released versions of WUA or the latest released versions of the file.
Here we explain how you can programmatically determine whether the version of WUA that is running on the computer meets your needs, that is, whether the version is the latest or at least current enough.
The third set of options works by limiting the bandwidth used by the SUS implementation, thereby controlling the load on the server and the network.
Note: Limiting the load on the SUS server or the network via the options described here will result in it taking longer for all the Windows XP systems to be updated, because the bottleneck is the server load.
For the vast majority of SUS implementations, server and network load will not be a concern and SUS administrators will not have to take mitigation actions described below, although it is recommended that the SUS administrator monitor the performance and load on the SUS server when the update is initially approved.
Under ideal conditions for a dedicated SUS server, assuming a 100 Mbps server network card capacity with 20% of this capacity consumed as overhead, it will take approximately 30 seconds for a SUS client to download the Windows XP SP2 update from the server.
Windows Update Agent (WUA) automatically updates itself when it is connected to a Windows Server Update Services (WSUS) server or to Windows Update.
