 ## Configure Unified Service Tags
 
 Unified Service Tags (USTs) connect traces, metrics, and logs by applying consistent tags across your telemetry. This makes it easier to navigate your observability data.
 
 Learn how to set USTs for:
 - [Linux][14]
 - [Docker][15]
+- [Windows][18]
 - [Kubernetes][16]
 
    **Note**: In Kubernetes, USTs must be set on both the Deployment object and the Pod template spec.

+
+## Overview
+
+With Single Step Instrumentation (SSI), you can automatically enable APM for your .NET Framework and .NET Core applications running on Windows IIS, using a single MSI command during the Datadog Agent installation. No separate SDK installation or code changes are required.
+
+## Enable APM on Windows
+
+**Note:** Only .NET applications running in IIS are supported for Single Step Instrumentation on Windows.
+
+To enable APM with Single Step Instrumentation on Windows:
+
+1. In Datadog, go to the Install Datadog [Windows Agent page][1] .
+1. In the **Customize your observability coverage** section, toggle **Application Performance Monitoring (APM)**.
+1. Copy and run the provided MSI install command on your Windows host.
+1. Restart the IIS applications you want instrumented. (You do not need to restart the entire IIS server.)
+
+After installation, the Agent automatically loads the Datadog .NET SDK into supported application processes to enable distributed tracing.
+
+## Set SDK Tracer Versions
+
+By default, Single Step Instrumentation installs the latest supported version of the Datadog .NET Tracer.
+
+If you need to pin a specific version:
+
+1. From the Windows Agent install page, after toggling **Application Performance Monitoring (APM)** instrumentation, select Customize library versions.
+1. Under .NET, choose the version you want to use.
+1. Copy the updated MSI command and run it on your host.
+
+## Remove Single Step APM instrumentation from your Agent
+
+
+To disable SSI for .NET on your host, run:
+
+```shell
+&"C:\Program Files\Datadog\Datadog Agent\bin\datadog-installer.exe" remove datadog-apm-library-dotnet
+```
