OS Activation / Licensing - AVD Test

Operating systems across physical, virtual, and cloud-based desktops must be properly licensed and activated to ensure continued functionality, security compliance, and access to updates. License activation validates the authenticity of the OS installation and enforces compliance with enterprise or vendor licensing agreements. In large or hybrid desktop environments, administrators often face challenges such as expired or invalid licenses, activation failures, or systems nearing the end of their activation grace period. Such issues can lead to restricted functionality, user disruptions, and compliance violations if not detected in time.

This test helps administrators continuously monitor the licensing and activation status of desktops by tracking key indicators such as the current license status, remaining time to license expiry, and available Windows rearm count. By providing early visibility into activation-related issues, the test enables timely corrective actions - such as reactivation or license renewal - ensuring uninterrupted operation, compliance, and stability across all desktop environments.

Target of the test : An Azure Virtual Desktop

Agent deploying the test : An internal agent

Outputs of the test : One set of results is reported for the system being monitored.

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed.
Host	The host for which the test is to be configured.
Port	The default port is NULL.
DD Frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. For instance, if you set to 1:1, it means that detailed measures will be generated every time this test runs, and also every time the test detects a problem.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
License status	Indicates the current status of the license.		The values that this measure can report and the numeric values they indicate have been listed in the table below: Measure Value Numeric Value Licensed - Permanently activated 1 Licensed - Time-based 2 Unknown 3 Within the grace period 4 Notification 5 Extended grace 6 Error 7 Expired 8 Note: By default, this measure can report the Measure Values mentioned above while indicating whether/not the updates are available. However, the graph of this measure is indicated using the numeric equivalents. The detailed diagnosis of this measure lists the Server name, Product key channel and the Details of the license.
Expiry Date	Indicates the number of days beyond which the license will expire.	Days	A decreasing value signals an approaching license expiry. Administrators should renew or reactivate the license before expiry to prevent functionality restrictions.
Remaining Windows rearm count	Indicates the number of times the license can be uninstalled and set to trial mode in case of transferring the license to another system.	Number	Rearm allows resetting the activation timer without requiring immediate license activation. A low or zero rearm count indicates that further activation resets are not possible, and the system must be properly licensed to avoid activation failures.
