Hi. Thank you for your question and reaching out.
Reinstall the Windows programs by default
The error "Sysprep was not able to confirm your Windows installation" may appear if you deleted some of the default Windows apps or if your Windows 11 computer is devoid of them. Therefore, this issue might be resolved by reinstalling every default program that comes with Windows 11. The Get-AppxPackage cmdlet in Windows PowerShell makes it simple to reinstall Windows system programs:
From the Start menu, launch Windows PowerShell with administrative rights, or right-click the Start menu and choose "Terminal (Admin)" from the selection that appears.
Additionally, PowerShell will start up automatically using Windows Terminal. After copying the following command into the PowerShell window, press Enter.
Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
The reinstallation of all the packages will take some time. Watch for it to finish. After that, restart your computer and see whether the issue still occurs.
