Windows 10: Upgrading from Windows 8.1 to 10, receiving "installation failed" error.

As the title explains, I've been attempting to upgrade to windows 10 from 8.1. I've tried many different fixes such as disabling my anti-virus, trouble shooting windows updates, doing and sfc /scannow check followed by a DISM.exe run to correct any errors. I've also tried stopping and starting certain processes in cmd. None of these have worked thus far.Attached are the logs from my recent attempt:2021-11-17 11:32:50, Error MOUPG CInstallUI::GetDefaultLanguage2027: Result = 0x80070002[gle=0x00000002] 2021-11-17 11:41:16, Error MOUPG CSetupManager::GetDUSetup

KB4025339 Fails Install 0x80070564

Thanks
I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!

 

Windows Updates failed to instal

I just did step one and they have just all installed.... thank you so much.... it was quite frustrating having that update window pop up every 5 minutes and failing to instal every time

Thanks mate
