    Error 0x800700a1


    I have a Windows 11 desktop with 2 drives. Primary is SSD and secondary is HD. I created a new folder for the downloads on secondary drive to store any future update downloads. Make it space on SSD drive. I made all Windows updates through last the end of September successful. Since last month when I updated the KB5019961 got that error 0x800700a1. How do I fix the futures Windows updates to my secondary drive. Thanks. Lawrence

    Error 0x800700a1

    Getting error 0x800700A1-0x2000C

    I have been trying to update my laptop to windows 10. I have the notice that it's ready and shows no problems. I downloaded the assistance tool and get as far as the screen showing supposed to be showing the updating progress ( blackscreen with large circle
    showing update progress). Nothing happens after that, instead it fails and reloads Windows 7. I get the error 0x800700A1-0x2000C and the following notice. The installation failed in the SAFE_OS phase with an error during the APPLY_IMAGE operation. I could
    really use some assistance with this.

    Thanks

    Don
