Windows Server 2022 Hardware Requirements
The minimum hardware floor for Windows Server 2022, with the technical reasoning behind each spec. CPU: 1.4 GHz x64 with DEP/NX/SLAT (use systeminfo to verify Hyper-V Requirements). RAM: 512 MB for Server Core, 2 GB for Server with Desktop Experience; ECC strongly recommended on physical hardware. Disk: 32 GB base, +4 GB for GUI; RAM > 16 GB scales pagefile.sys / hiberfil.sys / dump files (powercfg -h off reclaims hibernation space on servers that do not need it). Network: 1 Gbps PCIe-compliant Ethernet. TPM: optional in general, required for BitLocker, UEFI Secure Boot measurement, Credential Guard, and VBS - TPM 2.0 standard on modern servers. Includes the practical-vs-documented-minimum comparison table - the documented numbers are install-floors, real production sizing is several times higher on every dimension.
