Windows Server 2019 Remote Desktop Services 50 CALs — Add RDS Access to Your Existing Server
Windows Server 2019 Remote Desktop Services 50 CALs is a lifetime license key that adds 50 Remote Desktop Services Client Access Licenses (CALs) to an existing, already-activated Windows Server 2019 deployment, delivered by email. It’s built for IT admins and small businesses who already run Windows Server 2019 with the Remote Desktop Services role installed and need to license the users or devices connecting to it — not to activate the server operating system itself.
Buying CALs through standard Microsoft volume licensing channels usually means minimum order quantities, reseller paperwork, and multi-day turnaround. This pack gets you 50 genuine RDS CAL license keys emailed straight to you, ready to enter into your RD Licensing Manager the same day — as User CALs, Device CALs, or a combined 50 & 50 pack, depending on the option you choose at checkout.

Once installed on your RD Licensing server, these CALs let approved users or devices open Remote Desktop sessions against session-based or VM-based desktops — from managed office PCs or unmanaged personal laptops alike. Users connect the same way they always have; the CAL just tells your license server the connection is authorized.
For a company running a terminal server for a branch office, a call center, or a handful of remote staff, licensing per-device or per-user keeps costs predictable as the team grows or the device mix changes. You choose the licensing model that matches how your team actually connects, not the other way around.
What Is Included in Windows Server 2019 Remote Desktop Services CALs
Eight capabilities your RDS deployment gets once these CALs are installed on the license server.
Remote Desktop Session Host Access
Each CAL authorizes a user or device to open a session on an RD Session Host server. Use it for terminal-server style deployments where multiple people share one Windows Server 2019 machine.
User CALs & Device CALs, Your Choice
A User CAL covers one person across any number of devices; a Device CAL covers one device no matter who’s logged in. Pick whichever matches your environment — a hot-desking office usually wants Device CALs, remote staff on their own laptops usually want User CALs.
Active Directory CAL Tracking
RD Licensing servers can write CAL usage back to Active Directory objects without needing direct AD access, so admins can see license consumption alongside the rest of their directory data. Useful when the same team manages both AD and the RDS deployment.
GPU Virtualization & Discrete Device Assignment
Discrete Device Assignment passes a physical GPU through to a session, cutting network traffic and smoothing video playback for graphics-heavy workloads. Designers and engineers running CAD or video tools over RDP notice the difference immediately.
RemoteApp Notifications in Action Center
Published RemoteApps like Outlook can surface notifications directly in the Windows Action Center instead of a separate window. It keeps remote-published apps feeling like local ones for end users.
Single Sign-On for the Web Client
Users connecting through the RD Web Client authenticate once and get a streamlined session start, instead of re-entering credentials at every step. It’s a small change that removes a lot of daily friction for frequent remote users.
DTLS-Based Encryption
Sessions can use DTLS encryption for a faster, UDP-based secure channel instead of relying solely on TCP-based TLS. It’s part of the security hardening this RDS release brought over the 2016 version.
Express Updates for RD Licensing
The RD Licensing role supports Express Updates, which installs future cumulative updates faster by only downloading the changed binaries. That means less maintenance-window downtime for the server hosting your CALs.
Windows Server 2019 RDS CALs — Licensing That Matches How Your Team Connects
Four real scenarios covering Device CALs, User CALs, combined packs, and where this fits alongside your existing server license.
Device CALs: License the Machine, Not the Person
A Device CAL is tied to a specific piece of hardware — a shared kiosk PC, a reception desk terminal, a shift-work workstation — and covers whoever logs into it. If ten people rotate through three shared machines, three Device CALs cover the lot, regardless of how many different users sign in over the week.
This is usually the cheaper option when devices outnumber people, which is common in call centers, retail back-offices, and shared-terminal setups. You license the hardware once and stop worrying about headcount.
User CALs: One License Per Person, Any Device
A User CAL is tied to a person instead of a machine. That person can connect from their office desktop, a laptop at home, or a tablet on the road, and it’s still one license — the CAL follows the user, not the hardware.
This model fits remote and hybrid teams better than Device CALs do, since the same employee might reasonably connect from two or three different devices in a normal week without needing extra licenses.
Combined 50 & 50 Packs for Mixed Environments
Most real deployments aren’t purely one model or the other — a business might have a handful of shared reception PCs alongside a remote sales team on personal laptops. The combined 50 Users & 50 Devices option covers both cases in a single purchase instead of forcing you to pick one licensing model for the whole company.
You still install the CALs the same way, through the RD Licensing Manager on your license server — the combined pack just gives you both license types to allocate as your environment actually needs them.
CALs Add Access — They Don’t Activate the Server
It’s worth being direct about this: these CALs license Remote Desktop Services connections on a server that’s already running and activated. If you’re setting up a fresh Windows Server 2019 box and need the operating system itself activated, that’s a separate purchase — see Windows Server 2019 Standard Activation Key for that.
Once your server is activated and the RDS role is installed, these CALs are the piece that lets users and devices actually connect to it. Entering them into an already-running RD Licensing server is a five-minute task, not a reinstall or a reactivation.
Windows Server 2019 Remote Desktop Services 50 CALs
What is included with your purchase.
Genuine License Key by Email
You receive 50 genuine RDS CAL license keys by email within minutes of checkout — no physical packaging, no waiting on shipping. Copy the key straight into your RD Licensing Manager.
Lifetime License — Pay Once
These CALs are a one-time purchase with no recurring fee or expiry date. Once installed on your RD Licensing server, they stay valid for the life of that Windows Server 2019 deployment.
Online CAL Activation in Minutes
Installing the pack is done through the RD Licensing Manager, which activates the CALs against Microsoft’s licensing service online. There’s no phone call needed for this step.
RD Licensing Stays Current with Express Updates
Your license server keeps receiving Windows Server 2019 cumulative updates as normal, and the Express Updates feature speeds up how those updates install going forward. The CALs themselves don’t need separate updates once installed.
50-CAL Pack — User, Device, or Combined
Choose 50 User CALs, 50 Device CALs, or the combined 50 & 50 pack at checkout to match how your team actually connects. All three options work with session-based and virtual-machine-based RDS deployments on Windows Server 2019.
Activation Support Included
If you run into anything while entering the keys into your RD Licensing Manager, reach our support team by live chat, WhatsApp, or email and we’ll walk you through it.
Requires an existing, already-activated Windows Server 2019 deployment with the Remote Desktop Services role and an RD Licensing server configured — this product licenses connections, it does not activate the server operating system. Works with both session-based (RDSH) and virtual-machine-based RDS deployments, and supports connections from managed or unmanaged devices over a corporate network or the internet.
Windows Server 2019 Remote Desktop Services CALs — Common Questions
What buyers usually ask before installing these CALs on their RD Licensing server.
Does this key activate my Windows Server 2019 installation?
No. This pack only adds Remote Desktop Services CALs to a server that’s already running and activated — it can’t be used to activate the Windows Server 2019 operating system itself. If you need to activate the OS, that’s a separate license key.
What’s the actual difference between a User CAL and a Device CAL?
A User CAL licenses one person across any number of devices they use to connect; a Device CAL licenses one device no matter who logs into it. Choose User CALs for staff who connect from multiple devices, and Device CALs for shared or fixed workstations.
Does this license expire or renew?
No — this is a one-time, lifetime purchase. There’s no subscription, no renewal fee, and no expiry date once the CALs are installed on your RD Licensing server.
How do I actually install the CALs once I have the key?
Open Remote Desktop Licensing Manager on your RD Licensing server, add the license key under the appropriate CAL type (User or Device), and activate it online through Microsoft’s licensing service. If anything doesn’t go through cleanly, our support team can walk you through it.
