Window 11 upgrade has failed error code 0x8007007f
Window 11 upgrade has failed error code 0x8007007f
- Err0r404Copper ContributorI actually ran into this issue as well when attempting to run the Windows 11 Installer Assistant, the problem was that the process would get to 71% and then error out with the Error Code specified in this thread.
Similar to GreaterShrew issue, I ran everything on my device to ensure everything was updated regarding Windows Update, drivers and so forth. Ran the SFC actions and DISM commands, but did nothing to resolve the issue.
One method that worked for me was running the installer program as an "Administrator", sounds dumb as our windows profile are set to administrators but right-clicking the program and selecting "Run As Administrator" did the trick for me.
Otherwise, for anyone else that comes across this post at a later time, I would suggest the following as well:
Run the following commands in an Elevated Command Prompt:
SFC /scannow
dism /online /cleanup-image /scanhealth
dism /online /cleanup-image /restorhealth
Ensure all Windows updates are installed for your current OS build. Settings > Updates
Run the Windows11Assistant application as an Administrator
Reboot as necessary
Hope all this helps!!- mak56581Copper ContributorHello, the info with the "Administrator" made it work for me. Thank you
Only strange that MS not just tell me to do so! - treebluedogsCopper ContributorTried all these tips and still error
I need to know how to install 11 as administrator.
I don't know how to do it.

I reinstalled windows 11 where I kept my files and that is what worked for me.......make sure you a backup and disk image before you try. I use macrium and it's back up works like a charm treebluedogs

Run as admin worked for me as well to pass the 71% Barrier. Thanks so much!!
- rozeboosjeCopper ContributorMy "me too" for "Run as Administrator". Nice one.

Hi willk7
1. Open cmd in elevated mode, right-click on Command Prompt icon, and select Run as administrator.
2. Please execute the below commands step by step:
sfc /scannow dism /online /cleanup-image /scanhealth dism /online /cleanup-image /restorehealth
The first command will scan and fix system file corruption issues, second and third command will use DISM (Deployment Image Servicing and Management) tool to scan/restore the health of the windows installation image.
3. Reboot the computer and run Windows 11 Upgrade
I hope these steps could be helpful for you, please do not hesitate to contact me for any further assistance.

- Reza_AmeriSilver ContributorHave you ried running the PC Health Check app to verify if your system is ready for the upgrade?
Are you installing from the Windows Update or using the Windows installer file?- permataNTUCopper Contributor
Reza_Ameri hi, i tried installing from windows file I got on the internet. i cant download from the Windoes Update because windows 11 option is not appearing.
- Reza_AmeriSilver ContributorDid you download it from the official Microsoft website which is:
https://www.microsoft.com/en-us/software-download/windows11
Check your device's manufacturer website and download and install the latest driver.
Make sure report this issue using the Feedback Hub app.

Hello,
This is a known issue where you can bypass via install Win11 in Beta Channel then switching back to Dev Channel.
