For larger volumes, contact support and we will size the licensing with you.
Your Windows Server key licenses the machine — but Microsoft also requires a Client Access License (CAL) for every user or device that connects to it. Missing Windows Server CALs are the single most common finding in software audits, and the most expensive one to fix retroactively. Kymakers sells genuine User CALs, Device CALs and RDS CALs for Windows Server 2025 and 2022 at prices that make full compliance painless: instant email delivery, one-time payment, permanent validity.
| CAL type | Licenses | Choose when… |
|---|---|---|
| User CAL | One person, on unlimited devices | Staff each use a PC, laptop and phone — the standard choice for most offices |
| Device CAL | One device, used by unlimited people | Shift workers share terminals — clinics, warehouses, call centres, factories |
| RDS CAL | Remote Desktop sessions (user or device) | People log into remote desktops or published apps — required in addition to a standard CAL |
Rule of thumb: more devices than people → User CALs; more people than devices → Device CALs. Running Remote Desktop Services? You need RDS CALs on top.
Count every human (User CALs) or every endpoint (Device CALs) that touches the server — directly or indirectly. File shares, print services, authentication against Active Directory, intranet apps: they all count as access. A 20-person office with a domain controller needs 20 User CALs even if only five people open a file share daily. CALs are not concurrent — they license the user or device, not the simultaneous connection.
Microsoft audit settlements routinely run to tens of thousands — almost always for missing CALs rather than missing server keys. Genuine CAL packs from Kymakers cost a fraction of list price, arrive in minutes, never expire and close the compliance gap for good. One payment, permanent licenses, complete paper trail.
Choose your CAL type and quantity (5, 10, 25, 50-packs), check out, and your genuine license documentation arrives by email within minutes with clear installation steps — including RDS licensing-server activation for Remote Desktop deployments. Unsure of the right mix? Tell our 24/7 support how many people, devices and servers you run, and we’ll confirm the correct, cheapest structure before you pay.
Do I really need CALs if the server is internal only? Yes — any user or device authenticating or consuming a service needs one. Only anonymous public web access is exempt.
Do CALs install on the server? Standard User/Device CALs are legal entitlements (keep the documentation); RDS CALs are installed into the Remote Desktop licensing server.
Can I mix User and Device CALs? Yes — many businesses buy User CALs for office staff and Device CALs for shared shop-floor terminals.
Do 2022 CALs work with Server 2025? No — CALs must match or exceed the server version. 2025 CALs cover both.
What about SQL Server? SQL has its own licensing (per-core, or Server + SQL CALs) — see our SQL Server category or ask support.
