Window 11 upgrade has failed error code 0x8007007f
- Run as admin... of course!
Thx Err0r404 - Tried Salman's method and didnt work but thank you for the suggestion! Running as admin did it for me, However its strange, I didnt have to do this last time... All working thanks all
- I 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!!Err0r404This helped me too. I am only at 78% so far but at least I made it past the 71% threshold LOL. How running in admin mode made the difference I don't understand. Running an install app for upgrading to a newer version of the current OS should automatically set itself to admin mode and request login credentials if needed.
Run as admin worked for me as well to pass the 71% Barrier. Thanks so much!!
- My "me too" for "Run as Administrator". Nice one.
- Tried all these tips and still error
I need to know how to install 11 as administrator.
I don't know how to do it.
HELPI 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
Hello,
This is a known issue where you can bypass via install Win11 in Beta Channel then switching back to Dev Channel.
- Have 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?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.
- Did 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.
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 /restorehealthThe 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.
SalmanAhmed This seems to have worked my update has gone past 71%
- I did all that and I get the following error
"We couldn't update the system reserved partition" - I got an error on line 1:
PS C:\WINDOWS\system32> sfc /SCANNOW
Windows Resource Protection could not start the repair service.
Any suggestion on what the problem might be?I ended up uninstalling Windows and re-installing. That took care of the problem.
