    <p>The Windows32_Services class doesn't exist, so assuming which you are using the <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa394418%28v=vs.85%29.aspx" rel="nofollow noreferrer"><code>Win32_Service</code></a> WMI class you can improve the performance only returning the properties which you want to use, in this case the <code>PathName</code>, so change your WQL sentence to </p> <pre><code>SELECT PathName FROM Win32_Service Where Name='MyService' </code></pre> <p><strong>UPDATE</strong></p> <p>The observation made for <a href="https://stackoverflow.com/users/150605/bacon">@Bacon</a> is quite correct, since you know the name of thes service to retrieve, you can build the object path of the Win32_Service which look like</p> <pre><code>Win32_Service.Name="ServiceName" </code></pre> <p>And then using the <a href="http://msdn.microsoft.com/en-us/library/yeteazb7.aspx" rel="nofollow noreferrer"><code>ManagementObject</code></a> class you can retrieve the instance to the service in a fastest way.</p>

    1. COSince you're filtering by `Name`, which a key property of the [Win32_Service class](http://msdn.microsoft.com/en-us/library/windows/desktop/aa394418.aspx), it would be faster to just access the instance directly without doing the search: `string path = "Win32_Service.Name=\"MyService\""; ManagementObject service = new ManagementObject(path); string pathName = (string) service.GetPropertyValue("PathName");` But I think the author is saying that it takes a long time for WMI to initialize, not that the query is taking too long to execute.

    2. COYes, but using a query you're having to access the `Name` property of each `Win32_Service` instance. So, it's retrieving 25 properties of one instance vs. one property of all instances (on my 64-bit Windows 7 Professional laptop there are 188 services). In a quick test of 1,000 iterations of each method of retrieving the `PathName` property of a service, constructing a `ManagementObject` by path takes less than 10 seconds, whereas using a `ManagementObjectSearcher` takes about two minutes. Removing any `using` blocks and use of LINQ from the latter does get it down to about a minute.

    3. CO@Bacon, I misunderstood your original comment about using the object path of the instance with the `ManagementObject` instead of `ManagementObjectSearcher`, your observation is quite correct, Also getting a `ManagementObject` directly is much better than get a `ManagementObjectSearcher` and enum each instance.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
