About Windows
Windows 11 Pro adds BitLocker encryption, Remote Desktop hosting, Hyper-V and Group Policy management on top of Windows 11 Home, which makes it the usual choice for professionals and power users.
Windows 10 Pro still works on hardware that does not meet the Windows 11 requirements, but Microsoft ended its support on October 14, 2025. Check that your PC supports TPM 2.0 and Secure Boot before choosing Windows 11. See Windows 11 Pro vs Home for help choosing an edition.
