Windows 11 was publicly released yesterday and there are several ways users wanting to upgrade can go about installing it. In fact, Microsoft even made the TPM check bypass via registry hack official last night as a valid workaround for users on older unsupported PCs. Of course, the company issued its fair share of warnings.
Installation errors however can happen with anyone irrespective of whether you're running a supported system or not. For example, the image below shows an error code "0x8007007f" which is reported to happen around the 71% installation mark. This seems to be occurring when using the Installation Assistant.

Fortunately, there appears to be a fix discovered by Reddit users on the Windows 11 subreddit, and executing the installation as Administrator bypasses the certain user account control limitations that were perhaps giving this error code. Rebooting your device may also fix the issue.
There's also another error message popping up for some users. This one is dubbed "0x800F0830 - 0x20003", and its description says "The installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation".

Apparently, disabling the "Developer Mode" and uninstalling the Windows developer package from
"Apps & features" (via Repair Windows) inside the Settings menu may prevent this interruption.
