Lenovo Microsoft Windows Server 2022 Standard ROK (16 Core)
PRODUCT DESCRIPTION
Lenovo Microsoft Windows Server 2022 Standard ROK (16 Core) (7S05005PWW) - Local Support
The Base Server Licence: 16 Cores, With Installation Media and a Key
This is the licence that lets Windows Server 2022 Standard run on your server. As a Reseller Option Kit it includes the OEM licence — represented by a Microsoft Certificate of Authenticity label affixed to the server — along with the installation media. It covers up to 16 physical processor cores in one server, which is exactly Microsoft's minimum for any server.
Read This Before You Order: 16 Cores Is Often Not Enough
Microsoft licenses Windows Server by physical core, not by processor and not by virtual machine. Its rule is every physical core in the server must be licensed, with a minimum of 8 per processor and 16 per server. A modern two-socket Lenovo server with two 24-core processors has 48 cores and needs this base licence plus 32 more core licences. Buying only the base kit for such a machine leaves it under-licensed. There is a worked example further down this page.
And It Is for a Lenovo Server
A ROK is an OEM licence. Microsoft's OEM terms assign the licence "to the server with which you acquired the software" and state that OEM licences are "tied to the device on which the software is first installed". Lenovo sells these as pre-tested and optimised for Lenovo servers, and the Certificate of Authenticity label goes on the Lenovo chassis. If the server is not a Lenovo ThinkSystem or ThinkAgile, this is not the right licence — tell us and we will point you at the correct route.
You Will Also Need CALs
The server licence covers the software running on the hardware. It does not cover anyone connecting to it. Microsoft requires a Client Access Licence for every user or device that accesses the server, with only narrow exceptions. The 5-User CAL pack in the ordering table below is the companion SKU, and forgetting it is the single most common licensing mistake we see.
Licensing note. This is a software licence, not hardware, and the rules that govern it are Microsoft's rather than Lenovo's. Every rule quoted on this page comes from either Microsoft's published Product Terms and licensing guidance or Lenovo Press LP1079, and both are linked below so you can check them. Where Lenovo or Microsoft publishes no answer — and on OEM licensing there are several such gaps — this page says so rather than repeating what the trade generally assumes. Nothing on this page is legal or licensing-compliance advice. Licensing decisions carry audit consequences, so for anything beyond a straightforward deployment please talk to us and we will work it through with Lenovo and, where needed, with Microsoft. Note also that Lenovo's published last shipment date for the Windows Server 2022 range was 30 September 2025 — see the availability section below.
Lenovo Windows Server 2022 Standard ROK (16 Core) Datasheet — Technical Specifications
General
| Product | Lenovo Microsoft Windows Server 2022 Standard ROK (16 Core) |
| Lenovo Part Number | 7S05005PWW |
| Type | OEM server operating system licence, Reseller Option Kit, base 16-core licence with installation media |
| Publisher | Microsoft. Lenovo is the OEM channel through which the licence is sold |
| Availability | Lenovo Press states that the last shipment of Windows Server 2022 was 30 September 2025. Anything available now is channel stock, and the Windows Server 2025 equivalents are the current range. Ask us and we will quote both |
| Local Support | SourceIT supplies this licence in Singapore with a GST invoice and local assistance in working out the right licence set before you order |
What This Licence Covers
| Edition | Windows Server 2022 Standard |
| Licensing Model | Per physical core |
| Cores Covered | Up to 16 physical cores in one server |
| Microsoft's Minimum | Microsoft's Product Terms require a minimum of 8 core licences per physical processor and 16 per server. This base kit meets the 16-core server minimum exactly |
| Virtual Machines | Two operating system environments, or two Hyper-V isolated containers, when every physical core in the server is licensed. Each further pair of virtual machines requires all the server's cores to be licensed again — Microsoft calls this stacking |
| Media | Installation media is included with the kit |
| Language | Multilanguage |
| Lenovo Feature Code | S5YB |
If Your Server Has More Than 16 Cores
| The Rule | Every physical core must be licensed. Additional cores are covered by Additional Licence packs bought on top of this base kit |
| Additional 16-Core Pack | Lenovo part 7S05007PWW — Windows Server 2022 Standard Additional Licence, 16 core. No media and no key: it is licence entitlement only, so this base ROK is still required |
| Additional 2-Core Pack | Lenovo part 7S05007MWW — same, in 2-core increments |
| Worked Example | A server with two 24-core processors has 48 physical cores. That needs this base 16-core ROK plus 32 additional core licences — two 16-core packs, or sixteen 2-core packs |
| A Second, Subtler Trap | Core licences are counted against physical cores, not virtual machines. Four virtual machines on a 32-core host needs two complete sets of 32 core licences — 64 in total — because Standard grants two virtual machines per full set |
Standard Against Datacenter
| What Is Identical | The per-core model, the 8-per-processor and 16-per-server minimums, the CAL requirement, and the core Windows Server functionality |
| Standard | Two virtual machines per full set of core licences; further pairs require the whole server to be licensed again |
| Datacenter | Unlimited virtual operating system environments and unlimited Hyper-V isolated containers on the licensed server — no stacking |
| Datacenter Also Adds | Shielded VMs, which Standard does not have, and full Storage Replica where Standard is limited to a single volume up to 2 TB |
| Which to Buy | A physical or lightly virtualised server is cheaper on Standard. A host running several virtual machines reaches a crossover point where Datacenter is cheaper and simpler. Tell us the virtual-machine count and we will work out where you fall |
What a ROK Is, and What It Is Not
| ROK | Reseller Option Kit. Lenovo Press describes it as "the OEM license, represented by a Microsoft OS-COA label, that is sold by Lenovo's authorized resellers and distributors", with the installation media included |
| Intended Hardware | Lenovo sells these as "specifically pre-tested and optimized to install on Lenovo servers". This is a licence for a Lenovo server. If your server is not a Lenovo, tell us and we will point you at Microsoft volume or retail licensing instead |
| Is It Pre-Activated or BIOS-Locked? | Neither Lenovo nor Microsoft publishes an answer. Trade lore says ROK media performs a hardware check; no official document we could find states it, so we do not assert it |
| Transferable? | Microsoft's OEM terms are clear: OEM software "may NOT be transferred to another machine", and may pass to a third party only with the entire licensed server, including all Certificate of Authenticity labels. Lenovo publishes nothing of its own on ROK transferability |
| Reassignment | Microsoft applies a 90-day minimum before core licences or CALs may be reassigned to a different server, waived where hardware fails permanently |
Support
| Who Supports the Operating System | Not Microsoft directly. Microsoft's OEM terms direct customers to "the device manufacturer or installer for support options", and state that the system builder is required to support the software |
| Lenovo's Position | Lenovo Press directs OEM licence support enquiries to a Lenovo sales representative, and sells operating-system support as a separate service — Enterprise Server Software Support (ESS), described as 24x7x365 for critical problems and business hours for non-critical |
| Is Any Support Included? | Not published by Lenovo. Lenovo does not state whether ESS is bundled with a ROK or must be purchased separately. Assume separately, and ask us to quote it if you need a supported operating system |
Compatibility & Fit
How to work out what you actually need
Four questions decide the whole order, and we will happily answer them with you rather than leave you to it.
1. Is it a Lenovo server? A ROK is an OEM licence sold for and assigned to a Lenovo machine. If the answer is no, stop here and talk to us — Microsoft volume or retail licensing is the correct route and we can advise on it.
2. How many physical cores does the server have? Not processors, not virtual machines — physical cores, added up across every processor. Sixteen or fewer, and this base kit covers you. More than sixteen, and you need additional core licences on top: part 7S05007PWW in 16-core packs or 7S05007MWW in 2-core packs, both of which are licence-only with no media.
3. How many virtual machines? Standard grants two per complete set of core licences. Four virtual machines means buying the whole server's core count twice. If the answer is six or more, ask us to price Datacenter alongside — there is a crossover point and it is often lower than people expect.
4. How many people or devices will connect? Every one of them needs a Client Access Licence, in addition to this server licence. See the CAL SKU in the ordering table.
Why we would rather you asked than guessed. Server licensing is the one area of this catalogue where a wrong purchase is not simply an exchange — an under-licensed server is a compliance exposure that surfaces at audit, often years later and at a much larger number than the licence would have cost. Send us the server model, the processor configuration, the number of virtual machines you intend to run and the number of people or devices that will connect, and we will work out the exact licence set with you before anything is ordered. It costs you nothing and it is the part of this transaction where we can be most useful.
On availability: Windows Server 2022 is past Lenovo's last shipment date
Lenovo Press states plainly that the last shipment of Windows Server 2022 was 30 September 2025. What you are buying now is channel stock. That is not a reason to avoid it — a 2022 licence remains perfectly valid and Microsoft supports the product until 15 October 2031 under extended support — but it does mean two things. First, supply is finite: if you are planning a rollout, tell us the quantity early. Second, if you are buying for a project that has not started yet, Windows Server 2025 may be the better purchase, and its CALs cover 2022 and earlier while 2022 CALs do not cover 2025. Ask us and we will price both so you can decide with the numbers in front of you.
On downgrading to an earlier version. The right to run Windows Server 2019 or 2016 in place of 2022 already comes with this licence — Microsoft's OEM terms include it, and Lenovo confirms that "the license rules of the purchased version still apply". What the licence does not give you is media and an activation key for the older version, which is what the separate downgrade kit supplies. If you need to run 2019 on this licence, the 2022-to-2019 kit is in the ordering table above.

Two kinds of source govern this product and it is worth knowing which is which. Lenovo Press LP1079 is the only Lenovo document that covers this part number — there is no PSREF entry and no individual product guide for it. Everything about how the licence may be used comes from Microsoft, whose Product Terms and OEM licensing rules are linked above and are the authority. Where the two are silent — whether ROK media is BIOS-locked, whether support is included — this page says so.
Frequently Asked Questions — Lenovo Windows Server 2022 Standard ROK (16 Core)
How many core licences do I need?
As many as your server has physical cores, with a minimum of 8 per processor and 16 per server. This kit covers 16. A server with two 16-core processors has 32 cores and needs 16 more; two 24-core processors means 48 cores and 32 more. Send us the exact server configuration and we will do the arithmetic with you.
Can I use this on a Dell, HPE or self-built server?
No — this is the wrong SKU for that. A ROK is an OEM licence that Microsoft assigns to the server it is acquired with, and Lenovo sells it pre-tested for Lenovo servers with the Certificate of Authenticity label going on the Lenovo chassis. For non-Lenovo hardware you need Microsoft volume or retail licensing. Tell us what the server is and we will point you the right way rather than sell you this.
How many virtual machines can I run?
Two, when every physical core in the server is licensed. For four, you license all the cores twice. For six, three times. If you are running more than a handful of virtual machines, ask us to price Datacenter against Standard — Datacenter allows unlimited virtual machines on the licensed server and often works out cheaper at density.
Do I need CALs as well?
Yes. This licence covers the server software running on the hardware; it does not cover anyone connecting to it. Microsoft requires a Client Access Licence for every user or device that accesses the server. The exceptions are narrow — up to two people for administration purposes, access from another licensed server, and certain web and high-performance-computing workloads. The 5-User CAL pack is in the ordering table above.
Can I move this licence to a different server later?
No. Microsoft's OEM terms state that OEM software may not be transferred to another machine. It can pass to a new owner only together with the entire server, including the Certificate of Authenticity labels. If you expect to move licences between machines, that is an argument for volume licensing rather than OEM — talk to us before you buy.
Who do I call when something goes wrong with the operating system?
Not Microsoft. Microsoft's OEM terms direct you to the device manufacturer or installer, and Lenovo directs OEM licence support to a Lenovo sales representative. Lenovo sells operating-system support as a separate service called Enterprise Server Software Support. Lenovo does not publish whether any support is included with a ROK, so assume it is not and ask us to quote ESS if you need it.
Is Windows Server 2022 still current?
Not quite. Lenovo's published last shipment date was 30 September 2025, so this is channel stock, and Windows Server 2025 is the current range. The 2022 licence remains valid and Microsoft supports it under extended support until 15 October 2031. If your project has not started, ask us to price 2025 alongside — and note that 2025 CALs cover 2022 while 2022 CALs do not cover 2025.
