Some users get 0x8007007f error when upgrading Windows 11

PC users worldwide who meet the system requirements can now download and install the Windows 11 upgrade, but some people have encountered some problems during the installation process. Microsoft has admitted that Windows 11 has at least three known issues, but there are multiple installation issues that have not been notified that affect a small number of users. To download the 21H2 version of Windows 11, you can check whether it is available in Windows Update.

If it is not available, you can use Microsoft’s new Windows 11 Installation Assistant tool to force the installation of a new operating system. However, some people encountered general error messages. Some users seem to have failed to install Windows 11 through the installation assistant, resulting in an error 0x8007007f, because this error is really too general, and the root cause cannot be understood simply by looking at the error code.

This conflict seems to be related to Windows 10’s UAC permissions for installers, storage space, and drivers. It may also be caused by the incomplete update of the previous Windows 10 system. The error code 0x8007007f has been around 71% during the installation process, one user pointed out in a discussion on Reddit. The installation assistant failed to report an error, the error code is 0x8007007F, and no useful information was provided. Another user pointed out and described the wrong upgrade process.

In addition to Reddit, we have also observed similar reports on forums and Twitter. For most users, restarting the installation assistant with administrator privileges should resolve this error and allow the tool to download and install updates. At the same time, the vague error message may be related to the installation of certain drivers. In order to resolve the 0x8007007 error, you can restart the device or restart the installation process. You can also manually install the new driver from the manufacturer’s website.

Therefore, a faster solution might be to simply download the Windows 11 ISO, load it in File Explorer, and then run setup.exe. In addition, we observed another error message Ox8COF0830 – ox2W03.

Ox8COF0830-ox2W03 installation failed in the SAFE_OS phase, an error occurred during the INSTALL_UPDATES operation, the error message read. This problem also seems to be related to the driver, and there is no proper solution.

If you are suffering from Windows 11 upgrade issues that we did not cover, you can solve most of the problems of the installation process being stuck only by using the ISO image installation, and those who find themselves unable to install the upgrade anyway can only continue to use Windows 10. And continue to receive regular monthly updates from the company.
