Windows 10: Can't Update Windows 10 32Bit - Error 0x80070643

Hi There,I have been unable to update Win 10 Pro 32Bit I keep receiving a 0x80070643 error message.I have tried everything I could find to resolve this issue, but nothing worked.I finally noticed that the Win Pro 10 product key was the same as on my other PC now upgraded to 64 Bit Win Pro 11. Not sure how that happened.Both machines run fine, expect for windows update on the 32 bit machine.Could this be the problem causing the error message?I note that I entered a new product key for Windows 11, but that machine still reports the key as the original Win 10 key.I would really appreciate some

:)

 

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
