Hello!
Thank you for reaching out to Microsoft customer support.
Regarding your concern, the Windows Server Essentials 2016 Client Restore Service is designed to work with Windows 10 clients. Although there is no 32-bit version of Windows PE available for Windows 11, you can still use the Windows 10 version of Windows PE to install the Client Restore Service.
However, please note that if a Windows 11 client fails, the Client Restore Service may not function properly as it is not specifically designed for Windows 11. It is recommended to have a backup plan in place for such scenarios.
Best Regards,
Hania Lian
