This is all very annoying. I have tried at least 20 times over the last nine days to install KB5015814 on my fully compliant W11 Pro desktop, and have tried all of the credible suggestions I've seen here and on the Net, and the thing still won't install, which means I'm still stuck at 22000.739.
This update installed without any hiccups on my not-quite-compliant W11 Pro, and that machine updated to 22000.795 without any problems.
If anyone sees a *new* possible solution to this stubborn refusal of W11 Pro 22000.739 to accept 5015814 and update from 739 to 795, PLEASE post your solution here. If you do a Web search, you'll find that there are a GREAT MANY W11 users who can't get 5015814 to install.
(BTW, I've done an in-place twice, and the direct download of the msu three times, and troubleshooting, cleaning up, SFC and DISM and nothing kicks this thing enough to make Windows accept the installation. I will admit that I've deleted nothing from the CBS Logs folder, because I have no idea what I can and can't delete there.)
Any real, working solution will earn my undying gratitude.
