Microsoft has finally released Windows 11 , and as with every update that is released, there could not be any shortage of problems that some people encounter during the installation process.
Microsoft has already recognized at least three of these, but there are others that affect a small subset of users.
To download the latest version (21H2) of Windows 11, you can check if it appears in Windows Update. If not, you can use Microsoft's new Windows 11 Installation Assistant to force the new operating system to install.
However, sometimes an error occurs.
Windows 11 does not seem to be able to be installed via the Installation Assistant, displaying the "0x8007007f" error which is too general for anyone to understand. But it seems to be related to Windows 10 UAC for the installer, storage and drivers.
“Error 0x8007007f keeps popping up about 71% of the way through the installation,” one user wrote on Reddit. “Installation Assistant failed with error code 0x8007007F. Media Creation Tool has stopped working,” another user wrote, describing the upgrade process.
In addition to Reddit, there are similar reports on Twitter.
How To Fix Error 0x8007007f

To correct error 0x8007007, you can restart the device or restart the installation process. You can also manually install the new drivers from the manufacturer's website.
