 ## 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.
+With Single Step Instrumentation (SSI), you can enable APM for your Java and .NET applications on Windows VMs using a single Datadog Agent installation command.
 
 ## Enable APM on Windows
 
 <div class="alert alert-info">Before proceeding, confirm that your environment is compatible by reviewing the <a href="https://docs.datadoghq.com/tracing/trace_collection/automatic_instrumentation/single-step-apm/compatibility/">SSI compatibility guide.</a></div>
 
-To enable APM with Single Step Instrumentation on Windows:
+You can enable APM on Windows in the following ways:
+* Instrument only .NET applications on IIS
+* Instrument all Java and .NET applications across your entire Windows host
 
-1. In Datadog, go to the Install Datadog [Windows Agent page][1] .

+   1. Under **Instrumentation Configuration**, select **Customize Library Versions**.
    1. Under .NET, choose the version you want to use.
 
 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.

 ## Configure Unified Service Tags
 
 Unified Service Tags (USTs) apply consistent tags across traces, metrics, and logs, making it easier to navigate and correlate your observability data. Learn how to [set USTs for Windows services][2].
 
 ## Enable SDK-dependent products and features
 
-Once SSI loads the Datadog SDK into your applications and enables distributed tracing, you can configure additional products that rely on the SDK. These include capabilities such as Continuous Profiler, Application Security Monitoring, and trace ingestion controls.
