Security update KB2533623 no longer available

[florenzen]

The security update KB2533623 is no longer available for download from Microsoft. Does that mean a .NET Core Installation on Windows 7 is not possible anymore?

I know, Windows 7 is out of support but there is also Windows Embedded Standard which is based in that version and which still has support in industrial applications.

I am not able to download the msu file. When I click on the link for the Windows6.1-KB2533623-x86.msu (pointing to http://www.microsoft.com/download/details.aspx?familyid=c79c41b0-fbfb-4d61-b5d8-cadbe184b9fc) file on https://support.microsoft.com/en-us/help/2533623/microsoft-security-advisory-insecure-library-loading-could-allow-remot I the page I get "We're sorry, this download is no longer available."

However, I accidentally found the following reddit thread: https://www.reddit.com/r/windows/comments/ik7sp7/does_anybody_have_the_kb2533623_update_for/

The thread claims that KB2533623 is superseded by KB3063858 or KB4457144. As a test, I installed KB4457144 from https://www.catalog.update.microsoft.com/Search.aspx?q=KB4457144 and .NET 5 Preview 8 worked for me on Windows 7. (I did not check KB3063858.)

I had the link for the update from https://docs.microsoft.com/en-us/dotnet/core/install/windows?tabs=netcore31 since I did not find an equivalent page for .NET 5 Preview 8. Perhaps, the documentation could be updated to point to KB4457144.
