Windows 11 is officially out and it is a biggie. It has high system requirements, so anyone trying to upgrade from Windows 10 to Windows 11 must meet those requirements to upgrade.

It turns out that although a majority of Windows 10 users will be able to upgrade, citing they have required system hardware, some users have intercepted the message “Something went wrong” along with error code 0x8007007f.

A lot could go wrong here. To sum up, according to most user reports, this issue has affected those who tried Windows 11 Installation Assistant on their Windows 10-powered computers. Users have complaints that the update progresses until 70% and then see the error message.

It turns out the error code associated with this issue is rather generic. To sum it up, the error is allegedly being caused due to insufficient storage, outdated drivers, corrupt system files, or insufficient administrator permissions. Read along to know how you can fix it.

1. Restart Your PC

Your first point of combat to fix the Windows 11 update issue is to restart the PC. There’s no rocket science involved here; simply power down the device by going to Start Menu > tap on the Power option. Select Restart from the menu.restart computer windows 11

2. Run Windows 11 Installation Assistant as an Admin

The probability of intercepting error code 0x8007007f when upgrading to Windows 11 is higher while using Windows 11 Installation Assistant. It turns out that using an assistant does the job.

Outdated graphics drivers would render graphics cards either short of their full capacity or make them incompatible. Therefore, updating the driver that runs the graphics processor is crucial, and almost all OEMs have released updated versions of drivers to support Windows 11.

Assuming that an outdated graphics driver caused the system to not upgrade to Windows 11, here’s how you can upgrade to the latest driver and fix this issue.

  2. Enter command devmgmt.msc.Enter command devmgmt.msc

Third-party Antivirus programs installed on your computer can interfere with Windows 11 installation. If that’s a problem, I recommend uninstalling the antivirus so that you can upgrade to Windows 11. You can uninstall third-party antivirus by following the path

  • Navigate to Control Panel >> Uninstall a Program and Right-click on antivirus and Tap on the Uninstall button.Right-click on antivirus and Tap on Uninstall button

Error code 0x8007007f that you could get during the Windows 11 upgrade is laced with storage issues. It would help if you had quite a lot of space on your PC to ensure Windows 11 is installed correctly. I am talking about keeping at least 100GB or more space clear for the Windows installation drive to do the job without throwing the error.

7. Make Sure Your PC Has TPM 2.0

You’ll need TPM 2.0 on your PC to support Windows 11 because, without it, you won’t be able to upgrade. 

  • To verify if TPM 2.0 is enabled or not, press Win+R on your keyboard. Search for tpm.msc, which should open Trusted Platform Module Management.
  • Locate the section “Status”. See if it says, “The TPM is ready for use” or not. It must say so, which denotes your PC supports TPM 2.0.TPM is ready to use

If enabled: 

  1. Reboot the system and press any of said keys to enter BOIS mode F1, F2, F10, F11, or DEL.
  2. Navigate to Security > TPM Device, and select Available. Reboot the system and verify TPM.
