  3. Windows 10 Insider Preview, error installing Cumulative Update Preview for Windows 10 Version 20H2 for x64-based Systems (KB 4568831).

    I have 2 Windows 10 machines on insider preview. One is running fine, and recently installed Cumulative Update Preview for Windows 10 Version 20H2 for x64-based Systems (KB4568831).

    The other machine seems to install it, reboots, spins after reboot for quite some time (with the message updates are being installed etc.). After some time, it displays a message that "windows update we couldn't complete the updates undoing changes". Once
    it is done and I log in, I see that the same update is offered again. Looking in the logs I see the below message:

    "

    Installation Failure: Windows failed to install the following update with error 0x800F0920: 2020-07 Cumulative Update Preview for Windows 10 Version 20H2 for x64-based Systems (KB4568831).

    "

    Is anyone else seeing this as well?
