-### Auto Instrumentation for .NET on Windows
-
-***Warning:*** The `Environment` property in the
-`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC` registry key will
-be overwritten by the options specified below to enable/configure auto
-instrumentation for IIS. Use the
-`signalfx_dotnet_auto_instrumentation_additional_options` option (see below for
-details) to include any other environment variables required for IIS.
-
-**Note:** By default, IIS will be restarted with the `iisreset` command (if it
-exists) after installation/configuration. Applications ***not*** running within
-IIS need to be restarted/managed separately in order for any changes to take
-effect.
-
-- `with_signalfx_dotnet_auto_instrumentation` (Windows only): Whether to
-  install/manage [SignalFx Auto Instrumentation for .NET](
-  https://docs.splunk.com/Observability/gdi/get-data-in/application/dotnet/get-started.html).
-  When set to `true`, the `signalfx-dotnet-tracing` MSI package will be
-  downloaded and installed, and the Windows registry will be updated based on
-  the options below. (**default:** `false`)
-
-- `signalfx_dotnet_auto_instrumentation_version` (Windows only): Version of the
-  `signalfx-dotnet-tracing` MSI package to download and install from
-  [GitHub Releases](https://github.com/signalfx/signalfx-dotnet-tracing/releases).
-  (**default:** `1.1.0`)
-
-- `signalfx_dotnet_auto_instrumentation_msi_url` (Windows only): Specify the
-  URL to download the MSI from a custom host, for example
-  `https://my.host/signalfx-dotnet-tracing-1.0.0-x64.msi`. If specified, the
-  `signalfx_dotnet_auto_instrumentation_version` option is ignored.
-  (**default:** `https://github.com/signalfx/signalfx-dotnet-tracing/releases/download/v{{ signalfx_dotnet_auto_instrumentation_version }}/signalfx-dotnet-tracing-{{ signalfx_dotnet_auto_instrumentation_version }}-x64.msi`)
-
-- `signalfx_dotnet_auto_instrumentation_iisreset` (Windows only): By default,
-  the `iisreset.exe` command (if it exists) will be executed after
-  installation/configuration in order for any changes to take effect for IIS
-  applications. Set this option to `false` to skip this step if IIS is managed
-  separately or is not applicable. (**default:** `true`)
-
-- `signalfx_dotnet_auto_instrumentation_system_wide` (Windows only): By
-  default, the `Environment` property in the
-  `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC` registry key
-  will be configured for the following environment variables and any from the
-  `signalfx_dotnet_auto_instrumentation_additional_options` option to
-  enable/configure auto instrumentation for ***only*** IIS applications:
-  ```yaml
-  COR_ENABLE_PROFILING: true  # Required
-  COR_PROFILER: "{B4C89B0F-9908-4F73-9F59-0D77C5A06874}"  # Required
-  CORECLR_ENABLE_PROFILING: true  # Required
-  CORECLR_PROFILER: "{B4C89B0F-9908-4F73-9F59-0D77C5A06874}"  # Required
-  SIGNALFX_ENV: "{{ signalfx_dotnet_auto_instrumentation_environment }}"
-  SIGNALFX_PROFILER_ENABLED: "{{ signalfx_dotnet_auto_instrumentation_enable_profiler }}"
-  SIGNALFX_PROFILER_MEMORY_ENABLED: "{{ signalfx_dotnet_auto_instrumentation_enable_profiler_memory }}"
-  SIGNALFX_SERVICE_NAME: "{{ signalfx_dotnet_auto_instrumentation_service_name }}"
-  ```
-  Set this option to `true` to also add these environment variables and any
-  from the `signalfx_dotnet_auto_instrumentation_additional_options` option to
-  the
-  `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment`
-  registry key to enable/configure auto instrumentation for ***all*** .NET
-  applications on the node. (**default:** `false`)
-
-- `signalfx_dotnet_auto_instrumentation_environment` (Windows only): Configure
-  this option to set the "Environment" value to be reported to Splunk APM, for
-  example `production`. The value is assigned to the `SIGNALFX_ENV` environment
-  variable in the Windows registry (**default:** `''`, i.e. the "Environment"
-  will appear as `unknown` in Splunk APM for the instrumented
-  service/application)
-
-- `signalfx_dotnet_auto_instrumentation_service_name` (Windows only): Configure
-  this variable to override the [auto-generated service name](
-  https://docs.splunk.com/Observability/gdi/get-data-in/application/dotnet/configuration/advanced-dotnet-configuration.html#changing-the-default-service-name)
-  for the instrumented service/application, for example `my-service-name`. The
-  value is assigned to the `SIGNALFX_SERVICE_NAME` environment variable in the
-  Windows registry. (**default:** `''`)
-
-- `signalfx_dotnet_auto_instrumentation_enable_profiler` (Windows only): Set
-  this option to `true` to enable AlwaysOn Profiling. The value will be
-  assigned to the `SIGNALFX_PROFILER_ENABLED` environment variable in the
-  Windows registry. (**default:** `false`)
-
-- `signalfx_dotnet_auto_instrumentation_enable_profiler_memory` (Windows only):
-  Set this option to `true` to enable AlwaysOn Memory Profiling. The value will
-  be assigned to the `SIGNALFX_PROFILER_MEMORY_ENABLED` environment variable in
-  the Windows registry. (**default:** `false`)
-
-- `signalfx_dotnet_auto_instrumentation_additional_options` (Windows only):
-  Hash of additional options to be added to the Windows registry
-  ***in addition*** to the options above. (**default:** `{}`)
-
-  For example:
-  ```yaml
-  signalfx_dotnet_auto_instrumentation_additional_options: {
-    'SIGNALFX_VERSION': '1.2.3',
-    'SIGNALFX_FILE_LOG_ENABLED': false,
-    # Hint: If the signalfx_dotnet_auto_instrumentation_system_wide option is
-    # set to true, all .NET applications on the node will be instrumented. Use
-    # the following options to include/exclude processes from auto
-    # instrumentation.
-    'SIGNALFX_PROFILER_PROCESSES': 'MyApp.exe;dotnet.exe',
-    'SIGNALFX_PROFILER_EXCLUDE_PROCESSES': 'ReservedProcess.exe;powershell.exe',
-  }
-  ```
-  Check the [Advanced Configuration Guide](
-  https://docs.splunk.com/Observability/gdi/get-data-in/application/dotnet/configuration/advanced-dotnet-configuration.html)
-  for more details about the options above and other supported options.
-
-To uninstall the `signalfx-dotnet-tracing` MSI and disable auto
-instrumentation, include the following in your recipe and restart all
-applicable services:
-```
-windows_package 'SignalFx .NET Tracing 64-bit' do
-  action :remove
-end
-
-# If the "signalfx_dotnet_auto_instrumentation_system_wide" option was set to
-# "true", include the following to remove the values from the
-# "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
-# registry key:
-
-registry_key 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment' do
-  values [
-    { name: 'COR_ENABLE_PROFILING', type: :string, data: '' },
-    { name: 'COR_PROFILER', type: :string, data: '' },
-    { name: 'CORECLR_ENABLE_PROFILING', type: :string, data: '' },
-    { name: 'CORECLR_PROFILER', type: :string, data: '' },
-    { name: 'SIGNALFX_ENV', type: :string, data: '' },
-    { name: 'SIGNALFX_PROFILER_ENABLED', type: :string, data: '' },
-    { name: 'SIGNALFX_PROFILER_MEMORY_ENABLED', type: :string, data: '' },
-    { name: 'SIGNALFX_SERVICE_NAME', type: :string, data: '' },
