In 2025, migrating to Windows 11 remains a major challenge for businesses. With strict hardware requirements such as TPM 2.0 and Secure Boot, assessing the compatibility of a diverse hardware environment (Dell, HP, Lenovo, Asus, etc.) becomes crucial. Fortunately, PowerShell offers an automated solution that’s far more effective than Microsoft’s PC Health Check tool.
