On decommissioning of update servers for 2000, XP, (and Vista?) as of July 2019

[AstroSkipper]

And by the way did you restart your system after patching? If not, I would do that first and in next step a check of correct patched "wuaueng.dll" in folder system32.

Unfortunately I have to go offline for 30 minutes. If it is not too late for you, I will come back. Anyway, the best idea solving your error code is to do all the steps in my guide once more by verifying each step. Sometimes one has to do these steps more times to be successful.

I should use HxD, right? Since I will be comparing hexes of both files.

*this is optional*

@mina7601 Now I am online again. Are you still there? Any success?  Ok, maybe too late today. We will see tomorrow. So long.

@mina7601 I think I found the cause. Install this update: https://i430vx.net/files/XP/WindowsXP-MSI-4.5-KB942288-v3-x86.exe

Hello, I have followed the steps quite a few times and this is always the end result, I have done on a fresh install of Windows XP SP3 and I cannot get passed the Welcome screen of update.

Have you installed all these updates and activated Tls 1.2?

Yes, I have done all these updates, activated TLS 1.2, the patched version of the file is in system32 (I checked and its the patched version), I have ProxHTTPSProxy setup with AstroSkipper's config, I am able to get to the "Keep your computer up to date" page and pressing Express or Customize gives me this error

@mina7601 Hi. If you still stuck on Microsoft Update error code 0x80072F78 or you are not able to click the button "Check for Updates", then there are a few things to check additionally. Here a short list:
1. Go to Internet Explorer Options, Advanced. Check if TLS 1.2 is enabled. Disable in this tab "Check for server certificate revocation". Now configure in tab Security Internet Zone to standard, Trusted Zone to high with only these three urls related to MU:  http://www.update.microsoft.com, https://www.update.microsoft.com and http://update.microsoft.com (Do it by copy and paste to avoid misspelling).
2. Go to Windows Services. Three system services are absolutely important for MU: bits, wuauserv and cryptsvc. These services should have been started and set to automatic.
3. If the button "Check for updates" doesn't work on MU, close Internet Explorer, open MU from Start Menu again and in most cases it will load successfully. This is step 14 of my guide. Check step 15 too if you have a fresh installation. (I've numbered all the steps for better reference).
4.  Please upload a screenshot of ProxHTTPSProxy's log window. Your uploaded screenshot shows no connection to MU. At first the log window has to be empty. Then take a screenshot after calling up MU via http://fe2.update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en&g_sconsumersite=1. All other browsers or connections to internet should to be closed.
5. Now try to go on and make a second screenshot.
Here are two screenshots of ProxHTTPSProxy 1.5 REV3e taken from my Windows XP system while accessing MU, just for the purpose of comparing:
First screenshot after calling up MU before searching updates:

Kind regards, AstroSkipper

PS: I have updated the content of my "Complete guide for restoring Microsoft Update in IE". So if you still have problems, read the whole guide again and perform all steps once more by keeping the order of them!

The Check for Updates button does not work because the third page (http://update.microsoft.com) is blocked. You have to close IE and enter MU in the start menu.

EDIT: It magically broke but is now back to the same error code

Run this command in cmd: proxycfg -u

Same problem, some reason error code 0x80072F78 just doesn't want to go away. Anything else I can send like the Windows Log File?

Check the Internet options to see if the Tls 1.2 entry is there.
