Windows Server 2019 Remote Desktop Services License Free May 2026
Windows Server 2019, by default, allows two simultaneous administrative remote desktop connections without any RDS CALs. This is part of the "Remote Desktop for Administration" feature.
There is no "free version" of RDS for standard users. However, there are two specific scenarios where you do not need to purchase RDS Client Access Licenses (RDS CALs):
When you first install the Remote Desktop Session Host (RDSH) role, the server enters an unlicensed mode. In this mode, it allows unlimited concurrent connections for exactly 120 days. This grace period is designed for testing, proof-of-concept, and application compatibility checks.
You can reset this grace period exactly one time using the winrm command or the WMI ResetGracePeriodLD method. After that, the server demands valid licenses. windows server 2019 remote desktop services license free
After Day 120: The server will stop accepting new connections. Existing sessions may be blocked, and users will see an error: “The remote session was disconnected because there are no Remote Desktop client access licenses available for this computer.”
A quick Google search yields countless PowerShell scripts that reset the RDS grace period via slmgr /rearm. While these work for Windows client OS (Windows 10/11), they have limited success on Server 2019 RDS licensing server role. Most modern Server 2019 updates (KB500xxxx) have patched this loophole. If you find a script that works today, expect it to fail after the next cumulative update.

If you have landed on this page searching for a "Windows Server 2019 Remote Desktop Services license free," you are likely an IT administrator, a small business owner, or a tech enthusiast setting up a lab. You want to allow multiple users to connect simultaneously to a single server without paying the standard Client Access License (CAL) fees. The question is simple: Does a truly free, permanent RDS license exist for Windows Server 2019?
The short answer is no—for production environments. However, the long answer is nuanced. Microsoft provides a generous, legal grace period, and there are specific scenarios (evaluation, development, legacy licensing) where you can operate RDS without paying for a new license.
In this article, we will dissect exactly how to obtain, install, and manage a free temporary license for Windows Server 2019 RDS, the limitations involved, the legal risks, and alternative open-source solutions. When you first install the Remote Desktop Session
If you have reached this section, you have realized that "free" doesn't work for your business. Here is the cheapest legal way.
Searching for "Windows Server 2019 RDS license free" often leads to tools that modify the licensing DLLs (e.g., termsrv.dll) or emulate a KMS (Key Management Service) server.
Do not deploy these in any production or business environment. The risks include:
| Risk | Consequence |
| :--- | :--- |
| Legal Liability | Using cracked software violates Microsoft's EULA, resulting in fines up to $150,000 per instance under the Digital Millennium Copyright Act (DMCA) and software piracy laws. |
| Security Backdoors | Modified termsrv.dll files are common vectors for ransomware. Attackers embed persistent malware in these patches. |
| No Updates | Microsoft updates (especially cumulative updates for Windows Server 2019) will overwrite the patched DLL, breaking the "free" license and potentially locking all users out during business hours. |
| Audit Discovery | Microsoft SAM (Software Asset Management) audits or a simple slmgr /dli command will reveal licensing violations. |
