    I'm a member of the Windows Insider Program. I recently purchased a new PC with this configuration and am attempting to install a "regular" copy of Windows 11 Pro. But, during installation, process hangs at 27%, but it's attempting to save my data and applications. I'm desperately in need of an urgent repair. Anyone had a similar problem/issue and how did they solve it?

    Download SetupDiag from the Microsoft website and run it as Administrator. It will analyze the installation logs and tell you exactly why it failed (e.g., a specific driver or service), which you can then uninstall and try again

    The Windows Insider builds are development versions that can block normal upgrades. When you try to install a standard Windows 11 Pro license from an Insider build, the upgrade process often fails because the installer can't properly transition between these different update "channels." The 27% mark typically corresponds to the "checking for updates" phase of installation.
