    'Can't Complete Update'


    I am the custodian of several Lenovo laptop Computers for a Charity. They are installed with Win 8.1 and have operated satisfactorily for 12 months.
    I have successfully upgraded 3 of these units to Win 10, although each has taken about 12 hours to load and install the Important Updates and Win 10. The previous updates were performed many months earlier or never.

    On following the same procedure on a further identical unit, it again proceeds for many hours before displaying the message 'Cannot complete updates, Undoing Changes, Do not switch off the computer'. This message has been displayed for more than 12 hours and is obviously stuck in a loop. If I ignore the message and switch off, what will be the consequence? Will I be able to attempt a restore to pre-update status.

    In addition are there any precautions I should take prior to a further attempt to run the Windows update procedure. I have read elsewhere of the need to uninstall 3rd party virus checkers and firewalls. Windows Defender is already disabled.

    Any assistance would be gratefully received, particularly as I have to repeat the process on several more laptop units.

    Regards,

    If you are using a Windows 10 USB flash drive or DVD to upgrade to Windows 10, there is no need to do all the Windows 8/8.1 updates first. You can skip those hours. As you said, uninstall - not just turn off - all third party antivirus/anti-malware/anti-virus programs. I like to do a good disk cleanup using option 2 before the upgrade:
    Disk Cleanup - Open and Use in Windows 10 - Windows 10 Forums

    It works with Windows 8 too, and I believe Windows 7.

    Thank you for your comment.
    Even when I turn off power to the laptop and switch on again after a minute or two, the 'Cannot complete' message is re-displayed.
    I haave been using the Microsoft free upgrade and as I stated it worked perfectly well, although very slowly, on 3 identical units.
    How do I get the macine to re-boot in 'Safe Mose' to attempt a Restore procedure.

    regards,

    You can still do the Microsoft free upgrade from a Windows 10 USB flash drive or DVD. Use the Media Creation Tool to make one:
    Windows 10

    Scroll down to Download Tool Now. You will discover it is many, many times faster than the online upgrade. Do not boot from the USB flash drive or DVD. Insert it with the old Operating System running and then run setup.exe from the flash drive or DVD.

    To boot into safe mode, if it is still the Windows 8 boot loader, you would tap F8 as soon as the bios logo disappears in the boot sequence. If it is the Windows 10 boot loader then the very brute force way of forcing to boot into safe mode is to do a hard power off (hold down the power key) as soon as the Windows logo appears. Do that three times. The 4 power on sequence should boot into safe mode.

    Many thanks for the helpful suggestions.
    I have managed to restore the laptop to its' pre-calamity status of Win 8.1, but I still can;t fathom the cause.

    I have also dowwnloaded the Media Creation Tool onto a flash drive andd am optimistic that this will enable me to upgrade the remaining laptop units in less than 12 hours each.

    I hope you mean that you created a USB flash drive using the Media Creation Tool? You have to run the MCT on a computer and let it create a Windows 10 installation USB flash drive.

    Yes, it was an USB Flash Drive and it worked very well.

    Many thanks again for your helpful suggestions.
