The example seems to contain comments meant for internal (Microsoft) use

In the code example given on the page, there are several comments that say `<-- Keep this information secure! -->`:

```
// <-- Keep this information secure! -->
Console.WriteLine("CurrentDirectory: {0}", Environment.CurrentDirectory);

// <-- Keep this information secure! -->
Console.WriteLine("MachineName: {0}", Environment.MachineName);
```

This is confusing. It started to make sense when I looked at the result of the code sample:

> This example produces results similar to the following:
> (Any result that is lengthy or reveals information that should remain
secure has been omitted and marked "!---OMITTED---!".)
> …
> CurrentDirectory: C:\Documents and Settings\!---OMITTED---!
> ...
> MachineName: !---OMITTED---!

So it looks like those "keep this information secure" comments are meant for the documentation author as a reminder to redact sensitive information. At the moment those comments are confusing, and it may be worth removing them or adding context for the reader.

Also, I noticed that code indentation needs to be corrected as well.
