This HowTo is valid for Win7 SP1 and Vista SP2, which have been newly installed or haven't been updated for some time. It should also help on systems that were up-to-date last month - just install the missing updates from the list below in this case.

These instructions were only tested on Win7 SP1. However, the list of updates should speed up the search for updates on Vista SP2, too.

Solution to the issue

Install the following updates BEFORE letting Windows search for updates, to avoid this very search taking "forever":
KB Win7 x64 Win7 x86 Vista x64 Vista x86
KB3145739 Download Download Download Download
KB3078601, "loyal" companion since August 2015 Download Download Download Download
KB3087039 Download Download Download Download
KB3109094 Download Download Download Download

On newly installed Win7 SP1 systems it's not really necessary to install the updates from the list above; it's sufficient to install any of the current Windows Update Clients (December 2015 or later) from the table below. But since the updates from the list will be installed automatically anyway, it doesn't matter if they're installed manually beforehand.

To reduce memory and CPU usage while searching for updates, the following updates should be installed as well:

Steps to take after Windows installation
