So I have had this problem ever since I installed 24H2. It is this update: 2025-05 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5058411) Install error - 0x800f081f. It will not install, it tells me to retry.
So after reading other message boards I decided to reinstall Windows from scratch with the ISO, not keeping anything. This was in Feb. Then the March update came out and it would not install, so again I redid Windows. When it tried to update after the new install, it did not update, on a clean windows machine. So I downloaded a new ISO and reinstalled windows. When the April update came out it would not install, same error. I am NOT redoing windows every update! It takes too long! So I just left it alone and let it retry and retry. Now the May one just appeared and the April one mysteriously installed, but the May will not. For some reason the previous month will not install until the new month has come out? I have even tried manually downloading it and doing the update. I get this:
Windows Update Standalone Installer error: 0x800f0838. I am not redoing Windows, only to have the same thing happen next month. So aside from that I have done this:
I have plenty of disk space:

I did this:

I have tried this:
Navigate to C:\Windows\SoftwareDistribution and delete all files and folders.
Restart the Windows Update service and try installing the update again.
None of it works!
The only things that seem to work are a new windows update from a new ISO. Or waiting till the next update comes out. Everything on my computer is working perfectly. I haven't had a single problem with any apps or games. Everything else on my comp updates fine. It also will install all the other windows updates, except this one. Like ones for net framework and virus updates install fine. Instead of a reinstall windows with the ISO, so we can have the same problem next month, is there an actual fix?
