# <a id="windows-plugins"></a>Icinga 2 Windows plugins
To allow a basic monitoring of Windows clients Icinga 2 comes with a set of Windows only plugins. While trying to mirror the functionalities of their linux cousins from the monitoring-plugins package, the differences between Windows and Linux are too big to be able use the same CheckCommands for both systems.
One of the differences between the Windows plugins and their linux counterparts is that they consistently do not require thresholds to run, functioning like dummies without.
-## <a id"windows-plugins-thresholds"></a>Threshold syntax
+## <a id="windows-plugins-thresholds"></a>Threshold syntax
So not specified differently the thresholds for the plugins all follow the same pattern
Icinga 2 can use the `nscp client` command to run arbitrary NSClient++ checks.
You can enable these check commands by adding the following the include directive in your

+[icinga2.conf](4-configuring-icinga-2.md#icinga2-conf) configuration file:
