Hello everyone and a happy new year 2022!
This is my first post.
Sorry, I have to translate from German to English.
Since July 2021 I have been working on the update problem in Xp. As many people may know, the page has not been accessible for about 1 year. I found a workaround solution. To do this, click Internet Options in Internet Explorer, then go to the Trusted Sites option in the Security tab, then click Sites and add the pages http://www.update.microsoft.com and https://www.update.microsoft.com . Then set the security level to high and call up Windows Update. The page is already reloading. Unfortunately you get the error code 0x80072eff. The problem is that Internet Explorer is trying to download a file in the https protocol. After adding Tls 1.2 I still got the same error code. A few months have now passed. Until I got the idea that it could also be due to the certificate. I then downloaded a certificate trust list from Microsoft (https://docs.microsoft.com/de-de/security/trusted-root/release-notes). After I installed this certificate trust list, with a lot of luck and patience I was able to access the page. But unfortunately the search for updates failed. But after I downloaded the sha-2 patch from @max-h, I was actually able to search for and install updates again. The strange thing is that shortly after loading the page you have to click on Quick Search or Custom Search immediately, otherwise the search will fail with 0x80072efe. What is also strange is that I cannot open the page in a second window, otherwise the error 0x80072eff pops up again. What's also strange, when this page is open, the links in the Help and Support Center work too. Unfortunately, strangely enough, I am currently unable to access this website at all. But I am sure that the problem is with the certificate.
Sorry, the pictures are only in German.
Maybe someone can help.
