Windows Update error 8024A000 on Windows 10 Tech Preview

I was getting the error 8024A000 / 0x8024a000 when trying to install updates on Windows 10 Tech Preview Build 10041, and the solutions suggested on most forums didn't work. I've finally found a post in German with a working solution.

The problem was that I had re-enabled the old Windows Update GUI manually through a registry modification. This change needs to be reverted on this build. If you're also using the old GUI and getting this error, go to this registry key:

[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows Update \ UX]

And set the dword value of IsConvergedUpdateStackEnabled back to 1. After that, use the new Windows Update GUI on the Settings app.
