Restore Access to Windows Update v6


Microsoft Windows Update v6

Windows Update v6 as many people thought supposedly got "shutdown" in 2020 when Microsoft made the switch over to SHA-2 signing support instead of dual SHA-1 and SHA-2.

You can restore access to the Windows Update v6 website by getting it to work on your system by following the instructions below.


Warning: We are not responsible for anything that goes wrong to your system if an event like that were to occur. Please proceed at your own risk.

The following instructions apply to only Windows XP SP3 x86 & Windows XP SP2 x64, and Windows Server 2003 SP1/SP2 x86 & x64.

A video version of this tutorial is available here.

1. Firstly, you need to check your system's Service Pack to make sure it matches what's listed above. If they don't match, then you can download those Service Packs from our Service Pack Center.

2. Once your Service Pack is all set, you need to download the Windows Update SHA-2 patch. Download here.

3. After downloading the zip file, you need to extract it.

4. Once the zip file is extracted, run the Install.cmd file. It will automatically apply the patches so don't be alarmed.

5. After the patches have been applied, you will get a Windows File Protection prompt. Click Cancel.

6. Restart your PC for the patches to fully apply.

7. Next, you need to download the ProxHTTPSProxy 1.3a zip file. Download here.

8. Once you've downloaded the zip file, you need to extract it.

9. After the zip file has been extracted, you need to run "ProxHTTPSProxy.exe"

10. A command prompt window will open and it should create a new certificate file in your extracted folder. Once it's created you can close the Command Prompt window.

11. Open the newly created certificate and click on the "Install Certificate..." button.

12. Click next in the Certificate Import Wizard.

13. Select "Place all certificates in the following store".

20. Click on the "OK" button to close the Certificate window.

21. Now open the "ProxHTTPSProxy.exe" file to test the proxy.

22. If you get a Windows Firewall prompt, click "Unblock".

23. Next, we need to replace the config.ini file with a modified version. Download here.

24. Rename the old config.ini file in the Proxy Folder to something like "config-old.ini" and paste in the new config.ini file.

25. Run the "ProxHTTPSProxy.exe" to test it again.

26. Close out of the Proxy and head over to Control Panel > Network and Internet Connections > Internet Options.

27. Open the Security tab > Trusted Sites, click on "Default Level", and slide the slider all the way to the top until the security level is set to "High".

28. Then click on the "Sites..." button and a new window will popup.

29. Uncheck "Require server verification (https:) for all sites in this zone".

34. Beside "Secure:" under the "Proxy address to use" section, type "localhost" and under the "Port" section, type "8080" or whatever your FrontServer port is (Most likely to be 8080).

35. Then click on the "OK" button to close out of the Proxy Settings window.

36. Head over to the Advanced tab and scroll down all the way to the bottom.

37. Make sure "Use SSL 2.0" is unchecked and that "Use SSL 3.0 and Use TLS 1.0" are checked. Then click on the "Apply" button, then click on the "OK" button.

38. Next, open the "ProxHTTPSProxy.exe" file to open up the proxy and keep that running in the background whenever we use Windows Update v6.

39. Open up Internet Explorer, and head over to

40. There we go! You can now check for updates, download updates, and install updates on your system using Windows Update v6!
