Carlos: I just finished doing the second of 2 test clean installs of Windows Vista Business SP2 64-bit which I did yesterday and today. Step #17 of the newly updated guide pertains to IE9 (9.0.275). KB4575904 ESU LPP has stopped working again with Windows Update and is back to displaying the dreaded "C8000266" error code. That prevents post-EOL updates for Windows Server 2008 SP2 64-bit from being detected and displayed for install. It has been a time-consuming and frustrating 2 days.
I know that feeling! That update is such a PITA! I've ditched it now and won't be reinstalling it again. I spent way too much time last month getting it to work, only for the errors to come back again this month. It's just not worth it to me. I'm happy to just install the SMQR and IE9 updates manually a month.
Burdus77: I agree with you. Manually installing the new SMQR and IE9 updates is what I also plan to do every month - for now. On the plus side, a newly released NET Framework update is still being detected and installed by Windows Update.
If someone can enlighten me, what is KB5011543 (LCU) for Windows Server 2008 SP2? I can't find it at the Microsoft Update Catalog site or when doing a Google search.
This is what I have discovered when KB4575904 ESU LPP is installed before step #19 and is removed after step #23 in the guide: Vista_SHA2_WUC is deployed with option #1 so Windows Vista SP2 64-bit updates can be obtained. Windows Update is loaded and a "checking for updates" is done. After several minutes, 170+ updates appear. All 170+ updates (which are dated up to May 2017 EOL) are successfully downloaded and installed. The PC is restarted and Windows Update is loaded again and another "checking for updates" is done. No other updates appear. Vista_SHA2_WUC is deployed with option #2 so Windows Server 2008 SP2 64-bit can be obtained. Windows Update is loaded and a "checking for updates" is done. The "checking for updates" process continues for several hours and no updates appear. Windows Update is stopped and the PC is restarted. Windows Update is loaded again and another "checking for updates" is done. After only a few minutes, the "checking for updates" process displays the dreaded C8000266 error code. KB4575904 ESU LPP is uninstalled and the PC is restarted. Windows Update is loaded and a "checking for updates" is done. After several minutes, 50+ updates appear. All 50+ updates (which are dated up to January 2020 EOL) are successfully downloaded and installed. The PC is restarted and Windows Update is loaded again and another "checking for updates" is done. No post-EOL updates from February 2020 to March 2022 appear. Conclusion: The KB4575904 ESU LPP issue currently leaves Windows Server 2008 SP2 64-bit out of date by 26 months. Unless this issue miraculously gets resolved, the only remedy that I know is to obtain and manually install the new SMQR every month.
I'm in the process of doing another test clean install of Windows Vista SP2 64-bit. Normally in step #3, NET Framework 3.5 SP1 and then NET Framework 4.6.1 are installed. I tried installing NET Framework 4.6.2 this time after installing NET Framework 3.5 SP1, but it wouldn't install.
ruslanshchur: Thanks for your reply. I'm doing a few other things with this test clean install to try to resolve a ESU update issue, so NET Framework 4.6.2 and 4.7.2 can wait for now.
As ruslanschur said, you need the 2019 SHA-2 Support Update to install the .NET Framework 4.6.2. I didn't try .NET 4.7.2, but I am sure that 4.6.2 is working well and has no problems. In my install order I install .NET 4.6.2 after first update batch with SHA2 included.
I did another test clean install today of Windows Vista SP2 64-bit and then got it up to date to March 2022. (Note: I still didn't get the KB4575904 "C8000266" error code issue resolved) I tried installing Microsoft .NET Framework 4.6.2 afterward with its full off-line installer, but it wouldn't install. I'm going to stick with 4.6.1 and not worry about it.
I've done 3 different test installs today. Haven't had a single error in WU since I took out the ESU LPP update. That update has been yeeted into oblivion for me!
When I double-clicked the executable file to start the install process, the blue rotating circle appeared for a couple of seconds and then disappeared. No error message appeared. I right-clicked the executable file and then selected to run it as Administrator, but it did the same thing. Like I previously said, I'm not going to worry about getting 4.6.2 installed. I doubt that any apps or drivers that support Windows Vista SP2 64-bit need a NET Framework version newer than 4.6.1.
