Windows 7 Sept. 2020 Updates: BypassESU v8 required

[German]Windows 7 SP1 users who want to continue to install the September 2020 security updates from the ESU program but do not have an ESU key will need an updated version 8 of the BypassESU solution. Here is some information on the topic. 


What is update installation with BypassESU?

Since 14.1.2020 Windows 7 SP1 and Windows Server 2008 R2 have been dropped from support. To continue to install security updates in Windows 7 SP1 and Windows Server 2008 R2 after the end of support (14.1.2020) Microsoft offers Extended Security Update (ESU). In forums tinkerers have posted the tool BypassESU, with which updates can be obtained via Windows Update even without an ESU license in Windows 7 SP1. In the blog post Windows 7: Forcing February 2020 Security Updates – Part 1 I gave some hints about this solution.

September 2020 Updates need BypassESU v8

In my German blog somebody gave the feedback to the article Patchday: Updates für Windows 7/Server 2008 R2 (08.09.2020) that the tool BypassESU v7 didn't work for installing September 2020 security updates. A user wrote:

BypassESU has been updated to v8, v7 no longer works with the September updates. […]

Explanation of the authors: "They bumped ESU component version to 7602.24560 which exceeds KB4528069 version 7602.20587 this was expected, I'm surprised it took them 6 months to do it".

However, the developers have released an updated ESUBypass version v8, which allows to install the updates from September 2020 on Windows 7 SP1. A comment within the article Patchday: Updates für Windows 7/Server 2008 R2 (08.09.2020)  contains the GitHub links to the downloads. The colleagues from have taken up the topic as usual and point out that ByPassESU v7 does not work anymore. In this updated article you can find the necessary conditions that have to be fulfilled for the successful installation of September 2020 updates. 

  • All updates up to 14.1.2020 have already been installed (requires no ByPassESU)
  • Update KB4575903 for ESU licensing from 29.7.2020 was installed
  • ByPassESU v8 is required – the download addresses can be found at

Afterwards you should be able to install the security update from September 2020 (rollup, security-only) and the Servicing Stack Update (SSU). In case of problems, especially with the .NET Framework Update Sept. 2020, check the German comments here in the blog and at

    you can forget about BypassESU v8 now, guenni

    BypassESU v9 recently released as noted by (maybe to address problems with the v8 release & with recent Win7 Sept. 2020 updates):

  2. David says:

    Is there any sign of a version 10? I'm unable to manually install the most recent security update.

    All I get is "The update is not applicable to your computer"

    It's KB4571729. But strangely that update is also on some MS web pages as an update for August.

    I installed it in August, but it's not now listed in my list of installed updates in Programs and Features in Win 7.

  3. David says:

    I'm wrong. That update is indeed for August.

    November's update will be issued, I believe, Tuesday 13th.
