Windows 7 ESU Preparation Package Update KB4575903 (July 31, 2020)

win7[German]Microsoft has released a further preparation update KB4575903 for Windows systems with ESU license on July 31, 2020. These are Windows 7 SP1 and Windows Server 2008 R2 systems that have ordered the paid ESU support extension.


What is the ESU update KB4575903 for?

Update KB4575903 is for enterprise users of Windows 7 SP1 and Windows Server 2008 R2 who want to continue to receive security updates as part of the Extended Security Update Program after the support period ends on January 14, 2020.

I had reported here in the blog in more detail about this Extended Security Update Program, which is subject to a fee and only available for corporate customers (see links at the end of the article).

Details about ESU Update KB4575903

Update KB4575903 (Update for the Extended Security Updates (ESU) Licensing Preparation Package for Windows 7 SP1 and Windows Server 2008 R2 SP1) is available for the mentioned operating systems. Microsoft writes about it:

This update provides an additional set of licensing changes to enable installation of the ESU add-on key. This is one of the steps to prepare for installation of Extended Security Updates. For the full set of steps, please see KB4522133.

This means that the update will enable Windows 7 SP1 and Windows Server 2008 R2 SP1 to activate purchased ESU MAK keys so that you can continue to obtain and install Extended Security Updates by using Windows Update, WSUS, or the Microsoft Update Catalog. If you previously successfully installed and activated your ESU key on your Windows 7 SP1 device, you do not need to reinstall or reactivate it after you apply this update. A restart is required after you apply this update. (via)

      I know this – but this is a 'black' solution for consumers – it's not appropriate for business users – although I've introduced it within my blogs.

    the KB4575903 update supersedes/replaces the KB4538483 update.
    KB4538483 is no longer needed after installing KB4575903
