  1. Windows Update error 0x80070643


    Today I tried to check for Windows updates, it said that "they encountered an error" at the installation phase.

    The error code they gave me was 0x80070643.

    I tried running troubleshooter, resetting the update, and running a bunch of command prompt commands.
