Windows Editions & Features
Key Takeaways
- Windows 10 and 11 come in Home, Pro, Pro for Workstations, and Enterprise editions — Pro adds BitLocker encryption, Group Policy, Remote Desktop host, Hyper-V, and domain join capability.
- Windows 11 requires TPM 2.0, UEFI with Secure Boot, 4 GB RAM minimum, 64 GB storage, and a 1 GHz+ dual-core 64-bit CPU — these hardware requirements are frequently tested.
- BitLocker (Pro and above) provides full-disk encryption using TPM to protect data at rest — BitLocker To Go encrypts removable USB drives.
- Group Policy (gpedit.msc) is available only in Pro/Enterprise editions and allows administrators to configure user and computer settings centrally across domain-joined machines.
- Windows features like Hyper-V, Windows Sandbox, and Remote Desktop hosting are only available in Pro and above editions — Home edition has significant feature limitations.
