Does error code 0x8007007f occur when trying to upgrade to Windows 11 using the Windows 11 setup wizard? If yes, then you are on the right page. Although it’s quite annoying, after reading this article, you can easily solve this problem!

What is error code 0x8007007f?

This error code only appeared in users who tried to use the Windows 11 Setup Wizard. The error code does not allow the user to successfully upgrade to Windows 11.

Users reported that when using the setup wizard, the upgrade process stops for about 70% of the data. After a while, a message appears, “Something went wrong,” followed by another text: “Choose to try again, and if that doesn’t work, contact Microsoft support for help. Error code 0x8007007f”.

What causes error code 0x8007007f?

The error code in question, as we mentioned before, can be caused by a number of reasons. Before we show you how to solve the problem, let’s first go through the possible causes to better understand the problem. Let’s start with this one.

  • Not enough disk space: The first reason you might encounter this error code is that you don’t have enough free space on your system disk. The system disk is where Windows is installed, and obviously, that’s where Windows 11 is installed. If you have too little disk space, an error code will appear. In this case, you need to free up some disk space.
  • Outdated GPU drivers: In some cases, the problem may occur if the system has outdated graphics drivers installed. In this case, simply update the graphics drivers before running the Windows 11 setup wizard again.
  • Insufficient permissions: If you run the Windows 11 setup wizard without administrator rights, the problem may also occur. This can happen when a third-party service or application interferes with the installation process. This can be fixed by running the installation wizard as administrator.
  • Damaged system files: Another reason why the above error code may occur is that the system files on your computer are corrupt. If this is the case, you should repair the corrupted system files by performing an SFC check and then try to upgrade to Windows 11.

Disable your antivirus program

It’s important to know how to disable your antivirus program. Windows 10 comes with Microsoft Defender, which is a good basic protection against malware. However, you may sometimes need to disable it, such as when you’re installing another software that has its own protection against malware. Here’s a step-by-step guide on how to disable your antivirus program on Windows 10:

  1. Click the Start button, then click the Settings icon.
  2. In the Settings window, click Update & Security.
  3. Under the “Windows Security” heading, click the “Open Windows Defender Security Center” link.
  4. In the Windows Defender Security Center window, click the “Virus & threat protection” link.
  5. Under the “Virus & threat protection settings” heading, click the “Manage settings” link.
  6. In the “Virus & threat protection settings” section, toggle off the “Real-time protection” switch.
  7. You’ll see a warning message asking if you’re sure you want to turn off real-time protection. Click Yes to confirm and disable Microsoft Defender Antivirus.

If you’re using a third-party antivirus program, the steps will be similar. However, the specific steps may vary depending on the program you’re using.

Update your graphics driver

  1. Open the Device Manager. In Windows 10 and Windows 8, right-click or press-and-hold on the Start button, then choose Device Manager. In Windows 7, click on the Start button, then type “device manager” in the search box and hit Enter.
  2. Locate and expand the category of device that you want to update the driver for (in this case, it’s Display Adapters).
  3. 3Double-click or tap-and-hold on the device for which you need new drivers.
  4. In the Properties window that opens, go to the Driver tab.
  5. 5. Click or tap on Update Driver…
  6. Select Search automatically for updated driver software from the resulting options menu. If updated versions of the pre-installed drivers are available for your graphics card, they will be automatically installed in place of the old ones. If no updates are available, you’ll receive a message that says so and you won’t be able to continue past this point without manually installing drivers yourself as mentioned below.
  7. If you see this message instead of an option to Update Driver, it means that there are no further driver updates available for your computer and its graphics card. You can close the Device Manager window at this point as we won’t be needing it anymore.
  8. Restart your computer for the changes to take effect and see if you’re able to fix error 0x8007007f on Windows 10. If not, move on to the next method below.
