: If you purchased through older "Open License" or "Open Value" programs, your details are likely in the VLSC portal . Look under Licenses > Relationship Summary to find your Authorization and Agreement numbers. Email Confirmation/Reseller
: If you bought through a vendor (like CDW or a local reseller), search your inbox for a "Welcome Letter" or order confirmation. This document typically contains the necessary 5-by-5 product key (for retail) or agreement numbers (for volume). Physical Documentation
: Retail "per-user" or "per-device" CALs often ship as printed documents. These are essential for audits, as the keys themselves are not always stored in a readable format once installed on a server. Microsoft Learn How to Use the Key to Activate Licenses
Once you have your numbers, you must install them on your RD Licensing Server:

In the world of IT, finding a Remote Desktop Services (RDS) license key is less like finding a physical object and more like a digital scavenger hunt. Unlike standard software keys, RDS Client Access Licenses (CALs) are rarely stored as a simple string of text on the server once they are installed The Hunt for Your Keys
Depending on how you bought your licenses, your "key" is likely hidden in one of three places: The Microsoft Admin Portals : Most modern business licenses are found in the Microsoft 365 Admin Center Billing > Your products Volume Licensing Service Center (VLSC)
. In these portals, you aren't looking for a "key" but rather an Authorization Number License Number Your Email Inbox
: If you purchased through a reseller (like CDW or Pax8), the activation details—including the "License Key Pack ID"—were likely sent as an email attachment or included in your order confirmation. The Licensing Manager Server : If the licenses are already active, you can find the License Server ID by opening the RD Licensing Manager
on your server. While this won't show you the original purchase key, it is the ID you need if you ever have to call Microsoft to move those licenses to a new server. How to Retrieve or "See" Your Licenses
If you need to prove they exist or see how many you have left, follow these steps:
Finding a Remote Desktop Services (RDS) license key—specifically for Client Access Licenses (CALs)—depends entirely on how you purchased them. Unlike a standard Windows product key, RDS CALs are often "entitlement-based," meaning they are frequently managed via agreement numbers rather than a simple 25-character string. Where to Locate Your RDS License Details
The location of your license information is tied to your purchase method:
How to Find Your RDS License Key: A Step-by-Step Guide If you’re setting up a Remote Desktop Services (RDS) environment or moving your setup to a new server, you know that the "License Key" (often referred to as the Product Key or License Code) is the golden ticket that keeps everything running. Without it, your users will get booted once the 120-day grace period expires.
Finding that key isn't always as simple as looking for a sticker on a box anymore. Depending on how you purchased your licenses, your key might be tucked away in a digital portal or hidden within your server’s registry. Here is exactly where to look to find your RDS license key. 1. Check the Microsoft 365 Admin Center (VLSC Migration)
Microsoft has migrated most Volume Licensing Service Center (VLSC) features to the Microsoft 365 Admin Center. If your organization bought RDS CALs (Client Access Licenses) through a Volume Licensing program (Open License, Select Plus, or Enterprise Agreement), this is your first stop. How to find it: Log in to the Microsoft 365 Admin Center. Go to Billing > Your products. Select the Volume licensing tab. Click on Downloads & keys.
Search for "Remote Desktop Services" to see your specific Product Keys and License IDs. 2. Look in the Remote Desktop Licensing Manager how to find rds license key
If the licenses are already installed on a server and you just need to verify the details for documentation or migration, use the built-in management tool. How to find it: On your License Server, open Server Manager.
Click Tools > Remote Desktop Services > Remote Desktop Licensing Manager. Right-click your server name and select Properties.
Under the Required Information or Installation Method tabs, you can often see the License Server ID.
Note: For security reasons, the full 25-digit product key is usually masked once installed, but you can find the Agreement Number or License Code used to activate it. 3. Check Your Email and Digital Receipts
If you purchased RDS CALs through a retail vendor or a Cloud Solution Provider (CSP), the key was likely delivered digitally.
Search your inbox for: "Microsoft Licensing," "Product Key," "RDS CALs," or the name of the vendor (e.g., Dell, CDW, or Insight).
Retail Boxes: If you actually bought a physical retail box, the key will be on a card inside the packaging. It is a 25-character alphanumeric string. 4. Use PowerShell to Retrieve Keys (Advanced)
If you are trying to find the product key for the Windows Server OS itself (which often gets confused with the RDS CALs), you can use a PowerShell script to pull it from the BIOS or Registry.
The Command:Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey
Note: This typically pulls the OS key, not the specific RDS CAL pack keys, but it’s a helpful starting point if you’re doing a full server audit. 5. Contact Your Microsoft Partner or Reseller
If you’ve inherited a network and have no idea where the licenses came from, contact your Microsoft Partner (CSP). They keep records of every license purchased under your company’s tenant. They can provide a CSV export of all your keys, expiration dates, and agreement numbers. Understanding the Difference: License Key vs. License ID
When RDS asks for "information," it might be asking for one of three things: Product Key: The 25-digit code (Retail). License Code: A shorter code provided in the VLSC. Agreement Number: Used for Open Licensing.
If you are trying to activate a new server, you usually need the Agreement Number and the License Server ID rather than a traditional "key." What if I can’t find it at all?
If the key is lost and you have no record of purchase, you may have to contact Microsoft Clearinghouse. They are the department that handles RDS activation issues. You will likely need to provide proof of purchase to have them re-issue or identify your licensing credentials.
Finding a Remote Desktop Services (RDS) license key is less like finding a hidden password and more like auditing a digital warehouse. Whether you are migrating servers or just trying to prove to an auditor that you’re compliant, here is the roadmap to locating those keys. 1. The RDS Licensing Manager (The Front Door)
For most modern Windows Server setups, the key isn't stored in a text file; it’s managed through a specific GUI.
Open the Remote Desktop Licensing Manager (found under Administrative Tools). Right-click your server name and select Properties.
Under the Connection Method tab, you can often see the "License Program" (like Open License or Retail) used to activate it.
While this won’t show the full 25-digit key for security reasons, it provides the License Server ID and Agreement Number, which are the actual "keys" you need for Microsoft support or re-activation. 2. The Digital Search: Check Your Documentation
If you bought your licenses through a volume licensing program, the "key" is actually a contract.
VLSC (Volume Licensing Service Center): Most businesses find their keys here. Log in, go to the Downloads and Keys section, and search for "Remote Desktop Services."
Email Receipts: For retail CALs (Client Access Licenses), the 25-digit key is usually sent in a confirmation email or printed on a physical COA (Certificate of Authenticity) sticker. 3. The Power User Way: WMI and PowerShell
If you need to pull information for a report without clicking through menus, you can query the Windows Management Instrumentation (WMI) layer. Run this in PowerShell as an Administrator: powershell Get-WmiObject -Class Win32_TSLicenseKeyPack Use code with caution. Copied to clipboard
This command returns details about the installed license packs, including the KeyPackId. It won't spit out a retail 25-digit key, but it identifies exactly what is installed on the system. 4. The Registry (The Last Resort)
You can sometimes find the Product ID (not the raw key) in the registry, which helps identify the version of the license.
Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\Registration
This is mostly useful for troubleshooting "Grace Period" issues rather than recovering a lost key.
In the enterprise world, the Agreement Number is your true key. If you have that, Microsoft Clearinghouse can help you recover or move your licenses even if you've lost the original documentation. AI responses may include mistakes. Learn more
The Elusive RDS License Key: A Step-by-Step Guide to Finding It
Are you tired of searching for your Remote Desktop Services (RDS) license key? Do you feel like it's hiding in plain sight, but you just can't seem to locate it? You're not alone. Many IT professionals and system administrators have struggled to find their RDS license key, only to end up frustrated and confused. Introduction Remote Desktop Services (RDS) is a popular
In this blog post, we'll take a closer look at what an RDS license key is, why you need it, and most importantly, how to find it. So, let's dive in!
What is an RDS License Key?
Before we start searching for the license key, let's quickly cover what it is and why you need it. RDS, formerly known as Terminal Services, is a technology that allows multiple users to remotely access a Windows server or desktop. To use RDS, you need to have a valid license key, which is usually provided by Microsoft or a licensed reseller.
The RDS license key is a unique 25-character code that unlocks the RDS features on your server, allowing you to configure and manage remote desktop connections. Without a valid license key, you won't be able to activate RDS, and your remote desktop connections will be limited or non-functional.
Where to Find Your RDS License Key
Now that we've covered the basics, let's get to the good stuff – finding your RDS license key! Here are some steps to help you locate it:
If you purchased RDS licenses directly from Microsoft or a licensed reseller, check your email or documentation for the license key. You may have received an email with the subject line "Your RDS License Key" or something similar.
If your organization has a Microsoft Enterprise Agreement or a volume licensing agreement, you can find your RDS license key on the VLSC website. To access the VLSC, follow these steps:
If you have an RDS license server installed on your network, you can find the license key in the Remote Desktop Services Configuration console. Here's how:
Alternatively, you can also check your Active Directory (AD) for the RDS license key. To do this:
If you purchased RDS licenses from an IT provider or reseller, contact them to request a copy of your RDS license key. They may have recorded it for you or have access to it in their system.
As a last resort, you can try using PowerShell to retrieve your RDS license key. Here's a command you can use:
(Get-WmiObject -class Win32_RemoteDesktopServicesLicenseKey).LicenseKey
This command will retrieve the RDS license key from the WMI (Windows Management Instrumentation) repository. Note that this method requires administrative privileges and may not work on all systems.
Conclusion
Finding your RDS license key can be a challenge, but it's not impossible. By following these steps, you should be able to locate your RDS license key and activate your RDS features. Remember to keep your RDS license key safe and secure, as it's a critical component of your remote desktop infrastructure.
| What you want to find | Where to look | |----------------------|----------------| | Original product key (alphanumeric, for reinstall) | VLSC or original purchase email | | Key Pack ID (20-char, for license moves) | RDS Licensing Manager → Installed Licenses → Properties | | Number of CALs installed | RDS Licensing Manager → Installed Licenses view | | License type & expiration | RDS Licensing Manager → server properties |
If you’re simply trying to verify you have valid licenses, use the RDS Licensing Manager to check the issued count. If you need the actual key to set up a new license server, your best bet is always the Volume Licensing Service Center.

Finding a Remote Desktop Services (RDS) license key is not a matter of looking up a single code on the server, as these licenses are typically "entitlement-based" rather than simple product keys. Depending on how you purchased your licenses, you will find the necessary activation information in different digital portals or documentation. Where to Locate Your Licensing Information
The "key" you need depends on your purchase method. You will typically need an Authorization Number and a License/Agreement Number. Where do you find your CALs? - Spiceworks Community
Finding your Remote Desktop Services (RDS) license key depends on whether you have a physical retail product, a volume license agreement, or an already activated server. It is important to note that for many business setups, you don’t have a single 25-digit "key" but rather an agreement and authorization number. 1. Locate Physical or Digital Records
If you haven't installed the licenses yet, the key is typically found in your purchase documentation.
Retail/Boxed Copies: Look for a COA sticker or card inside the product box containing a 25-digit product key.
Digital/Email Orders: Search your inbox for a confirmation email from Microsoft or your reseller. It usually contains the License Key or Agreement Number.
Volume Licensing (VLSC): Most businesses find their details in the Microsoft Volume Licensing Service Center (VLSC). Log in and go to Licenses > Relationship Summary.
Click on the specific License ID to see the Authorization Number and License Number.
Microsoft 365 Admin Center: For newer subscriptions, check Billing > Your products > Volume licensing. 2. View Details on an Active Server Where do you find your CALs? - Spiceworks Community
Finding a Remote Desktop Services (RDS) license key—often referred to as a Client Access License (CAL)—can be a source of frustration because Microsoft doesn’t typically provide a "key" in the traditional sense (like a 25-digit code on a sticker) for modern volume licensing. Instead, finding and managing these licenses requires navigating specific administrative tools and portals. 1. Check the RDS Licensing Manager
If the licenses are already installed on your server, the Remote Desktop Licensing Manager is the primary place to find details about them.
How to access: On your Windows Server, go to Start > Administrative Tools > Remote Desktop Services > Remote Desktop Licensing Manager. Open the Remote Desktop Services License Manager: You
What you’ll find: You will see a list of installed license packs. While this won't show you a raw "product key," it will display the License Program, the Agreement Number (or Authorization/License numbers), and the quantity of CALs. These numbers are what you actually need if you ever have to rebuild the server or move the licenses. 2. The Microsoft 365 Admin Center (Formerly VLSC)
For most businesses, RDS licenses are purchased through Volume Licensing. Microsoft has migrated the old Volume Licensing Service Center (VLSC) into the Microsoft 365 Admin Center. Where to go: Log in to the Microsoft 365 Admin Center.
The path: Navigate to Billing > Your products > Volume licensing.
Downloads & Keys: From here, you can view your agreements. Under the "Downloads & Keys" tab for your specific RDS version, you will find the Authorization and License numbers required to activate the licenses on your server. 3. Retail Boxes and Email Confirmations
If you didn't buy through a Volume License agreement (e.g., you bought a "Retail" pack for a small business):
Physical Box: If it was a physical purchase, the key is on a card inside the packaging.
Digital Retail: If bought through a third-party vendor or the Microsoft Store, search your email for "Product Key" or "License Confirmation." These will provide a standard 25-character key that you enter directly into the "Install Licenses" wizard in the RD Licensing Manager. 4. Using PowerShell (For Active Servers)
If you are trying to find details about the current licensing configuration via command line, you can use WMI (Windows Management Instrumentation) through PowerShell: powershell
Get-WmiObject -Class Win32_TerminalServiceSetting -Namespace "root\CIMV2\TerminalServices" Use code with caution. Copied to clipboard
This won't spit out a hidden key, but it will confirm your Licensing Mode (Per User or Per Device) and the Specified Licensing Servers, which helps you track down where the keys were originally installed. Summary of Terms
To "find" your key for activation, you usually need one of three pairs:
License Number and Authorization Number (Volume Open License) Agreement Number (Select, Enterprise, or School agreements) Retail Product Key (25-digit code)
If you have lost all documentation and the server is dead, your best bet is to contact the Microsoft Activation Center or your Cloud Solution Provider (CSP), as they can look up your purchase history using your company’s domain or tax ID.
If you have already installed RDS CALs on a license server and need the key for another server:
Open PowerShell as Administrator:
Run Command to Get License Details:
Get-WindowsFeature | Where-Object Name -eq RDS-LICENSING
Specific License Key Command:

Finding a Remote Desktop Services (RDS) license key is a process that depends entirely on how you purchased the software and which version of Windows Server you are running. Unlike consumer software, RDS licenses—often called Client Access Licenses (CALs)—are rarely printed on a sticker or stored in a simple text file. They are digital assets managed through Microsoft’s licensing portals or embedded within documentation provided by a reseller.
To locate your keys, you must first identify your purchase channel. If you bought your licenses through a Volume Licensing program, such as Open Value or Select Plus, your primary resource is the Microsoft 365 Admin Center or the older Volume Licensing Service Center (VLSC). After logging in with your organizational credentials, you can navigate to the billing or licensing section to view your purchase history. There, you will find the License Agreement numbers and Authorization numbers. In many modern deployments, you do not actually enter a "key" in the traditional sense; instead, you enter these agreement numbers into the RD Licensing Manager to activate the server's ability to issue tokens to users.
If you purchased RDS CALs through a Retail channel, the key is typically found on a physical "Product Key Card" or within a confirmation email if purchased digitally. These are 25-character alphanumeric codes. Retail keys are increasingly rare in corporate environments but are still common for small businesses. If the physical card is lost and the email is deleted, recovering the key may require contacting the vendor directly with proof of purchase.
For those using Service Provider License Agreements (SPLA), the process is different. In this model, you generally do not have a permanent key. Instead, you report usage monthly to your provider, and they ensure your infrastructure remains compliant. The "key" in this scenario is effectively the credentials and agreement numbers provided by your hosting partner or Microsoft representative.
Once you have identified the numbers or codes, you must interact with the Remote Desktop Licensing Manager tool on your Windows Server. This utility is where the "finding" and "activating" processes meet. By right-clicking the server name and selecting "Install Licenses," a wizard will guide you through entering your Agreement Number or Retail Key. If you are trying to find what is currently installed on a server to move it to a new one, you can use the "Manage Licenses" option in the same tool to migrate or rebuild the database.
It is important to understand that RDS licenses are not "extracted" from the registry like a Windows OS key. They are records of entitlement. If you are auditing an existing server and cannot find the documentation, your best course of action is to run a Licensing Diagnosis from the Server Manager. This will tell you the current licensing mode and the discovery state of the license server, though it will not reveal the secret key itself for security reasons.
If all digital and physical trails fail, Microsoft’s Clearinghouse is the final point of contact. This is a department dedicated to activating and managing license servers. By calling their support line, you can often recover your licensing information by providing your company name, contact information, and any partial details about the original purchase. While time-consuming, this is the most reliable way to restore a lost RDS licensing environment without repurchasing the CALs. Microsoft directly third-party vendor Volume License Agreement number Is the server already running , or are you setting it up for the first time I can provide specific PowerShell commands navigation steps based on your answers.
To find your RDS (Remote Desktop Services) license key (also called a RDS CAL key or license code), you typically need to check where your organization stores Volume Licensing information. RDS CALs are not product keys entered during Windows setup—they are licenses added to a Remote Desktop License Server.
Here’s how to locate it:
If you manage a Windows Server environment with Remote Desktop Services (RDS), you may need to locate your RDS license key—whether for reinstallation, auditing, or moving to a new license server. This guide explains where RDS license keys are stored, how to retrieve them, and critical legal notes.
| You need | Look for | |----------|-----------| | RDS CAL license key (to install on license server) | 25-character code from VLSC or reseller | | RDS CAL key pack ID (already installed on server) | Found in Licensing Manager, cannot reinstall elsewhere | | Windows Server product key | Different from RDS CAL – not for licensing users/devices |
Never underestimate the power of a simple search. Many administrators lose keys because they land in spam folders.
