I have a client who is getting the following error in Windows Update:
Windows 10 couldn't be installed
Failed: 1 update
Error(s) found:
80004004-40019 Windows Update encountered an unknown error.
My client claims they never agreed to install Windows 10 (and I believe them).
OS is Windows 7 Pro 64-bit.
I have run Never10 and sfc /scannow.
If I reboot the PC and go into Windows Update, the error message is still there.
My client does not want Windows 10, they just want to get rid of this update message. Clipboard01.jpg
GWX Control Panel works very well long term on several Windows 7 systems I have here including one virtual machine that I want to be Windows 7 forever.

In control panel, programs and features, updates uninstall updates that could have caused this. After that run windows updates again.

Thanks for the replies. I will try GWX.
Rindi - can you tell me which updates they would be please?
John, reinstalling windows is not a viable option. This will cost my customer way too much money to fix a problem Microsoft has caused. I was hoping for a solution to the problem. Reinstalling the OS will fix any problem. That is not a realistic solution.

So then you should have deleted the question because the selected answer did not appear to fit the situation either

No, the answer I gave the points to was the most helpful and may be of help to others with similar problems.
"Hi. I had the same issue as your client for one of my clients. Windows Update Error 80004004-40019 after aborting a Windows 10 installation. The solution is to run the following in CMD: "reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade\Rollback /f"
Reboot and check for updates. It may error for 2-3 times, but check once more and you should be golden. No more Windows 10 failed error in Windows Update."
I haven't tried it but it may be of help to others with the same problem.
