Windows 10: 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.

error 0x80070643 (update)

Hey

Try to apply the update manually As suggested by Microsoft. I just wrote a
step by step guide.

However be sure that the update itself is downloaded and that the installation part is failing, and not the downloading part.

Hope it helps you
