Windows Update[German]Some Windows users are facing issues with the security updates released on April 9, 2019. Now it became known, that also Mc Afee as virus protection solution probably is causing slow a system start with the April 2019 update KB4493472 in Windows 7.


After Microsoft released several security updates for Windows on April 9, 2019, users are facing issues. The security updates led to installation errors, and a short time later it was clear that this was due to installed security solutions.

  • Diverse Sophos Schutzlösungen,
  • Antivirus-Software von Avast

were responsible for the installation problems. I had published the article Windows patchday issues–one week later (April 17, 2019). Microsoft has also added some hints in the KB articles of the updates. In the meantime, the antivirus manufacturers have published support articles or updates to help those affected.

Mc Afee users also affected

Meanwhile, Microsoft has revised the article on Update KB4493472 for the Monthly Rollup for Windows 7 Service Pack 1 and Windows Server 2008 R2 Service Pack 1 several times and added the Known Issues entries. The Known Issues section now reads:

Microsoft is currently investigating this issue with McAfee. For instructions for McAfee customers, see the following McAfee support articles:
