We look at the hardware or system requirements for using Windows Server 2025. We also discuss the upgrade paths from other Windows server versions to Windows Server 2025 below.
The system requirements for Windows Server 2025 apply to the following editions:
- Windows Server 2025 with desktop experience
- Windows Server 2025 Server core installation
The requirements below also apply to the following editions:
- Standard edition of Windows Server 2025
- Datacenter edition of Windows Server 2025
The system requirements for installing and running Windows Server 2025 are segregated into basis of processor requirements, RAM requirements, Storage requirements and Networking requirements.
Processor requirements for Windows Server 2025
- 1.4 GHz 64-bit processor
- Compatible with x64 instruction set
- Support for NX and DEP
- Support for CMPXCHG16b, LAHF/SAHF, and PrefetchW instructions
- Support for Second Level Address Translation (EPT or NPT)
- Support for the SSE4.2 (Streaming SIMD Extensions 4.2) instruction set
- Support for the POPCNT instruction
You can use the Sysinternal utlitity of Coreinfo to find out if the CPU is compatible with the minimum requirements for Windows Server 2025.
RAM requirements for Windows Server 2025
- ECC (Error Correcting Code) type or similar type of RAM is required
- Minimum RAM of 512 MB for installing Windows Server 2025 Server core installation
- Minimum RAM of 2 GB for installing Windows Server 2025 with desktop experience
Storage requirements for Windows Server 2025
Computers that run Windows Server must include a storage adapter that is compliant with the PCI Express architecture specification. Servers classified as hard disk drives must not use Parallel Advanced Technology Attachment (PATA) for persistent storage devices.
- The absolute minimum storage space required for Windows Server 2025 is 32 GB.
However, for most practical considerations, the disk requirements would go up as other resources increase. With higher RAM, you could also require a proportionally higher disk space allocation. This is because higher RAM would translate into higher page file size and considerably higher paging.
Networking requirements for Windows Server 2025
The network adapter for Windows Server 2025 must be PCI Express compatible.
- 1 Gbps or higher speed network adapter is required for Windows Server 2025
TPM requirements for Windows Server 2025
Trusted Platform Module (TPM) is required for specific use-case scenarios like Bitlock device encryption, Windows Hello and others, to securely create and store cryptographic keys, and to confirm that the operating system and firmware on your device are what they’re supposed to be, and haven’t been tampered with.
If you do not need these features or services on Windows Server 2025, you can skip the TPM requirements.
The following TPM requirements are needed for Windows Server 2025 (should you want to use TPM 2.0 compatible features):
- Hardware-based TPMs must implement version 2.0 of the TPM specification.
- TPMs that implement version 2.0 must have an EK certificate that is either pre-provisioned to the TPM by the hardware vendor or be capable of being retrieved by the device during the first boot.
- TPMs that implement version 2.0 must ship with SHA-256 PCR banks and implement PCRs 0 through 23 for SHA-256. It is acceptable to ship TPMs with a single switchable PCR bank that can be used for both SHA-1 and SHA-256 measurements.

The minimum hardware requirements for Windows Server 2025 (Server Core and Server with Desktop Experience) are as listed below. These requirements are applicable for both Windows Server Standard and Windows Server Datacenter editions.
If your computer’s hardware configuration is less than the requirements specified here, Windows Server 2025 may not install properly in your computer.
Please note that below specified numbers are the very minimum hardware requirements for Windows Server 2025 (Server Core and Server with Desktop Experience) to install and run. If you planning to run high resource consuming applications or services in your Windows Server 2025 computer, it is always better to pre-calculate the hardware resource requirements of those applications or services, and then plan the hardware configuration of your Windows Server 2025 accordingly.
Processor
Minimum processor requirements to install Windows Server 2022 is listed below.
- Clock speed : 1.4 GHz
- Processor architecture type : 64–bit Processor
- Instruction set : x64 Compatible
- Support for DEP/NX Protection : Should support DEP (Data Execution Prevention)/NX (No–Execute). DEP and NX features help to prevent buffer overflow attacks.
- Support for PrefetchW, CMPXCHG16b (Compare–and–Exchange), and LAHF/SAHF : PrefetchW (Pre-fetch) fetches resources required for a program earlier than the resources are required so that programs run faster. LAHF (Load AH from Flags) and SAHF (Store AH into Flags) are used to load and store instructions for certain status flags. These are the features for virtualization.
- SLAT (Second Level Address Translation) : Second Level Address Translation (SLAT), is a virtualization technology, implemented at the hardware level. SLAT is a required feature of the processor to run Windows Server 2025 Operating System. Hyper–V uses SLAT to optimize the available resources. Intel calls Second Level Address Translation (SLAT) technology as Extended Page Tables (EPT) and AMD calls Second Level Address Translation (SLAT) as Nested Page Tables (NPT).
Memory
- Minimum memory requirement : Minimum memory size required to install Windows Server 2025 as Server Core is 512 MB and with Desktop experience is 2 GB as bare-metal Operating Systems.
If you try to install Windows Server 2025 as a Guest Operating System in a Virtual Machine with exact 512 MB as RAM, the installation will fail, showing no available memory. Following image shows the error message when I tried to install Windows Server 2025 on a Virtual Machine, with exactly 512 MB memory.
I suggest 2 GB of minimum memory for Windows Server 2025 Server Core installations and minimum 4 GB memory for Windows Server 2025 with Desktop experience installations. 4 GB of memory is very common even for today’s mobile phones.
- ECC (Error Correcting Code) : Errors are possible in physical RAM due to hardware related issues or electrical noises. Error Correction Code (ECC) supported memory cards may correct these errors in the memory. ECC is a mathematical operation on the data stored in the RAM memory and ensures that the data in the memory is correct. Note that ECC memories are not common in normal PC or laptop memory cards. ECC supported memory cards are costly than normal memory cards, and ECC memories are more commonly used in Servers or Workstations.
Storage controller
PCI Express standard-based Storage controller.
Minimum storage requirement
Windows Server 2025 requires minimum 32 GB storage space. 32 GB storage space is the very basic storage requirement. For the smooth running of Windows Server 2025 Operating System, the suggested minimum storage space is 64 GB or more.
Ethernet Adapter
Minimum 1 Gbps speed is required.
PCI Express standard-based Ethernet adapter.
Pre-boot Execution Environment (PXE boot) for network boot and network-based Windows Server 2025 installation.
Other requirements for Windows Server 2025
- A decent bandwidth internet connection (to receive the latest updated installation files or updates from Microsoft).
- Keyboard and Mouse.
- DVD Drive (A DVD Drive is required if you have a DVD burnt Windows Server 2025 installation media and you are planning to boot and install Windows Server 2025 from that DVD disk).
- Graphics, Super VGA (1024 x 768) or higher-resolution.
- UEFI 2.3.1c-based system and firmware that supports secure boot.
- Trusted Platform Module 2.0 (TPM 2.0) – A TPM chip is necessary for Windows Server 2025 for features like BitLocker Encryption. Please visit the following link to learn more about the TPM requirements for Windows Server 2025.
