Windows 7: Forcing February 2020 Security Updates – Part 1

win7[German]Still using Windows 7 and interested installing the security updates from February 2020, although support for the operating system in January 2020 has fallen out of support? In this blog post I will outline an overview of several options.


I waited until early March 2020 to see if there were serious vulnerabilities in Windows 7. Currently a Windows 7 system needs the security updates for February 2020 mentioned within the two blog posts below.

If possible, these two updates should be installed on Windows 7 SP1 to protect the system against vulnerabilities.

The status of my ESU system

I have equipped my computer with Windows 7 SP1 Ultimate I use on a daily base with an ESU license for one year. So the system should receive security updates via Windows Update. Unfortunately, this is not the case – although an allegedly valid and activated ESU license is available, there is no sign of automatic security updates. But I'm not alone, some other people are facing the same.

When I run the update troubleshooter for Windows 7, an error is reported, but it cannot be fixed. On the other hand, Windows 7 updates for Microsoft Security Essentials (MSE) via Windows Update are received. I've no clue, why ESU failed partially, and I don't have the nerve to investigate further where the ESU license is now stuck and why Windows Update doesn't find any security updates on the system.

I have solved the situation very pragmatically for this system. Since I did not have installed rollup updates via Windows Update in the past – I use security-only updates – I downloaded the Windows 7 SP1 security-only update KB4537813 and the security update KB4537767 for IE 11 from February 2020 manually from the Microsoft Update Catalog and then also manually installed it. This worked due to the ESU license on that machine.

Update Installation with BypassESU

In forums, some people have posted the tool BypassESU, which is supposed to enable to receive further updates via Windows Update even without an ESU license in Windows 7 SP1. In my German blog there was this discussion on February 12, 2020, dealing with the fact, that older version doesn't work anymore. But the developers have released an updated version that enabled to install the February 2020 updates for Windows 7 SP1. 


The colleagues at has an article about BypassESU about this tool. And German site offers within this article a download link for BypassESU-v5.7z . The .z archive file need to be unpacked (password is 2020) into a local folder. A readme explains how to install. This should allow the update installation to work even without an ESU license.

I have tested this variant on a netbook with Windows 7 SP1 Home. The experience is not really positive.

  • While the updates were installed without problems until January 2020, the attempt to install February 2020 Security-only update KB4537813 constantly drops an error message that the Module Installer needs to be updated. The KBs linked in the KB posts did not work because the hotfixes were no longer present. 
  • Finally I tried the following approach without success and then let Windows Update check for updates. It was an update orgy of sorts, with updates being installed backwards from December 2019 to September 2019. At some point I was able to install the security-only update KB4537813.

For users who like to experiment this is surely a way – for the average user this road it's probably to stony. On Facebook I also received an note from a user telling me that the solution caused issues with autostart, which remained even after uninstalling. I didn't verify that.

Patch Windows 7 without ESU/BypassESU

I got this German comment von Blog-Leser Ralf Lindemann (danke). by blog reader Ralf Lindemann (thanks). The colleagues of German site have described a solution here to install the updates for February 2020 without BypassESU. An English explanation is available from Martin Brinkman at (see the section 'Our colleagues over at Deskmodder found another option that supports the installation of the latest SSU').

On my netbook I had no success with this attempt because the module installer was reported as outdated. I then took the approach described in the previous section and had success to install the missing security-online updates manually. But I could not say, which of the two solutions outlined here did the trick.

My overall conclusion: Using the ESU approach whether from Microsoft (payed) or the alternative solution, it's a mess. In part 2 I show how I used the 0patch agent to secure a second netbook on which the above solutions with ByPassESU did not work at all (the batch files crashed).
