I am trying to install KB4592438 for Windows 10 20H2. The patch is downloaded without any issue. But the installation fails and the screen starts showing - Undoing changes Don't turn off your computer. The error message is - Some update files are missing or have problems. We'll try to download the update again later. Error code: (0x80070003).
