If you are a customer seeking to determine Windows 11 eligibility for your device, please use PC Health Check. For Windows support life cycles please see Windows 11 Home and Pro - Microsoft Lifecycle.
This specification details the processors that Original Equipment Manufacturers (OEM) can use to manufacture new PCs that include Windows Products (including Custom Images). Updates to this specification may be released in the future as requirements change.
For each listed edition, OEMs must use only the processors listed, as specified in the tables below. The requirements below apply whenever the edition below is pre-installed or provided on external media, including as downgrade or down edition software.
If after the inclusion of a processor series in this specification ("Listed Processor"), a processor becomes commercially available that uses the same naming convention or identifier as a Listed Processor but has additional or different features or functionality ("New Processor"), OEMs must not use New Processor for Customer Systems without Microsoft's prior written permission. If an OEM believes a processor has been omitted from this list, please contact your Microsoft OEM or ODM Account Manager.
Some product editions or edition/processor configurations listed below may have no or limited support. Information on support is available at Microsoft Support Policy and Microsoft Lifecycle FAQ. Customers who have specific hardware support questions should contact the OEM of their PC.
NOTE: The list of supported processors above does not in itself determine Microsoft support for Windows Server. The listing is a prerequisite for system certification. Only systems based on the above approved processors can be certified for Windows Server. Unless otherwise noted, Microsoft will continue to evaluate the processor list for a given OS release and update the list as new appropriate processors are available in market.
To install Windows Server correctly, your computer must meet the minimum hardware requirements outlined in this article. If your computer falls short of these requirements, the product may not install properly. Actual requirements vary based on your system configuration, applications, and features that are installed.
Unless otherwise specified, these minimum hardware requirements apply to all installation options (Server Core and Server with Desktop Experience) for both Windows Server Standard and Windows Server Datacenter editions.
The highly diverse scope of potential deployments makes it unrealistic to state recommended hardware requirements that would be generally applicable. Consult documentation for each of the server roles you intend to deploy for more details about the resource needs of particular server roles. For the best results, conduct test deployments to determine appropriate hardware requirements for your particular deployment scenarios.
Processor performance depends not only on the clock frequency of the processor, but also on the number of processor cores and the size of the processor cache. The following are the processor requirements.
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. Windows Server also doesn't allow PATA, Advanced Technology Attachment (ATA), Integrated Drive Electronics (IDE), and Enhanced Integrated Drive Electronic (EIDE) for boot, page, or data drives.
The minimum specifications are only suggested for prototyping and testing of Tableau Server. The installer checks for the minimum system requirements and will not proceed on computers with less than these hardware minimums:
We recommend deploying Tableau Prep Conductor on a dedicated node with a minimum of 4 cores and 16 GB of memory. Additional resources may be needed depending on the use case. Contact Tableau for sizing and technical guidance.
The Tableau Resource Monitoring tool has two components - an agent that is installed on each node of the Tableau Server cluster it is monitoring, and the RMT Server for processing and hosting the web service. A separate machine/VM is needed for the RMT Server, where all processing and analysis takes place. The minimum specifications for the RMT Server are:
For RMT Server installations that match the minimum hardware specified above, the Resource Monitoring Tool can provide performance reporting for Tableau Server deployments serving up to 10,000 views per hour.
For deployments with more view loads per hour, or very high numbers of background jobs, data delays may occur. In these cases, you may need to upgrade your hardware.
The Content Migration Tool is run from a Windows computer and is able to connect to Tableau Servers with Advanced Management enabled. To review compatible versions of Tableau Server and Content Migration Tool, please check here. The minimum specifications are:
Supports Microsoft Active Directory, SAML 2.0, OpenID Connect, and built-in Tableau users and groups for user authentication and group membership definitions. Kerberos support for Microsoft SQL Server, Microsoft SQL Server Analysis Services and Cloudera Impala. LDAP for Tableau Server on Linux.
All Tableau products operate in virtualized environments when they are configured with the proper underlying operating system and minimum hardware requirements. CPUs must support SSE4.2 and POPCNT instruction sets so any Processor Compatibility mode must be disabled. We recommend VM deployments with dedicated CPU affinity.
Microsoft has offered Standard and Datacenter editions of its Windows Server operating systems for several years, which continued with Windows Server 2022. However, the company introduced a new product called the Windows Server 2022 Datacenter Azure edition. As the name implies, this edition ties server workloads more closely to the Microsoft cloud platform and offers unique features to tempt customers who want easier patching and other perks.
Microsoft decided to drop the Windows Server semi-annual channel that catered to organizations interested in emerging server technologies and stick with the Long-Term Servicing Channel, which produces a major feature release around every two years. All Windows Server 2022 editions follow Microsoft's fixed lifecycle policy and will receive five years of mainstream support followed by five years of extended support. While Microsoft always recommends a clean install of its server OS, Windows Server 2022 supports in-place upgrades from the two previous Windows Server releases.
Windows Server 2022 Standard and Datacenter editions share the same hardware requirements. Both require a 1.4 GHz, 64-bit CPU and 512 MB of RAM; for the Desktop Experience GUI-based version, the system needs 2 GB of RAM. Additionally, 32 GB of disk space are required.
These minimum hardware requirements will not be sufficient to run a workload with decent performance. Even Microsoft's own documentation points out the minimum requirements just to install Windows Server 2022 require at least 800 MB of RAM. Once Windows Server has been installed, the RAM can be decreased to 512 MB if necessary. As a best practice, organizations should match server hardware to the workload.
Both Standard Edition and Datacenter Edition can run on an unlimited number of cores, but both editions are limited to a total of 64 sockets, which must be 64-bit. Likewise, both editions support a maximum of 48 TB of RAM.
Every time Microsoft releases a new Windows Server product, it deprecates some features. In the case of Windows Server 2022, Microsoft removed the Internet Storage Name Service, the protocol used to find and work with iSCSI systems on the network.
Administrators who deploy the server core version of Windows Server should note that Microsoft plans to stop developing the Server Configuration tool (sconfig) and remove it from the next Windows server version. The sconfig utility will still run upon sign-in, but Window Server 2022 will use PowerShell as the default shell rather than the command prompt.
Other features Microsoft will not develop further include the Windows Deployment Services boot.wim image deployment, and it deactivated the Local Security Authority Remote Protocol interface used to connect to Encrypting File System encrypted files over the network.
Microsoft designed Windows Server 2022 Standard for physical machines or environments that are minimally virtualized. The retail price for Standard edition is $1,069 for use up to 16 cores. Systems with more than 16 cores will require additional licenses to cover each physical core on the CPU. Additionally, each client that accesses a Standard edition server requires a Client Access License (CAL).
Windows Server 2022 Standard largely has the same feature set as the Datacenter edition with some minor variations. For example, Standard edition limits the Storage Replica feature to a single partnership with one resource group and a 2 TB volume. Similarly, Standard edition only supports inherited activation if it is running as a guest on a Datacenter edition server. Standard edition also lacks support for software-defined networking and the Storage Spaces Direct software-defined storage feature.
The biggest difference between the Standard and Datacenter editions relates to virtual-machine licensing. Both editions support an unlimited number of Windows Server containers. However, the Standard edition limits this to two operating systems per license, meaning a Standard edition server can run a parent operating system and a single Hyper-V virtual machine or a single Hyper-V container. In contrast, a Datacenter edition license allows for an unlimited number of Hyper-V virtual machines or Hyper-V containers.
Like the Standard edition, this license allows Windows Server to run on up to 16 cores with additional licenses required for CPUs with more cores. CALs are also required for each client that accesses the server.
