Just click Start, select All Programs, and then select Windows Update.
When you get to the Windows Update page, you'll see a single, very large update waiting in the queue (Figure A).
Reboot the system after the script is finished, and you're done. If you intend to install Windows Updates on a whole network of systems, it's probably better to use some dedicated solution for this, e.g.
Last week, Microsoft officially unleashed Windows Vista Service Pack 1 ("SP1") to the public at large.
As is the tradition for some folks, when it comes to a new Windows operating system, the SP1 stage signals that the time is right to upgrade from Windows XP. However, I wholeheartedly recommend that you upgrade your system to Vista SP1.
It's sufficient to install one of the Servicing Stack Updates. Important: One of the Servicing Stack Updates is required before July 2016 Rollup can be installed! The answer is simple: This particular update contains a more recent (as far as I know the latest) version of the Update Agent.
With this update the time needed to search for new updates is reasonable, almost regardless of the updates installed on the system; the search times vary, of course, but not as ridiculously much as without July 2016 Rollup.
