            The name of the current user, or <span class="code">NOT AVAILABLE</span> when the 
            underlying runtime has no support for retrieving the name of the 
            current user.
            <div class="OH_CollapsibleAreaRegion"><div class="OH_regiontitle">Remarks</div><div class="OH_CollapsibleArea_HrDiv"><hr class="OH_CollapsibleArea_Hr" /></div></div><div class="OH_clear"> </div><p>
            Calls <span class="code">WindowsIdentity.GetCurrent().Name</span> to get the name of
            the current windows user.
            </p><p>
            To improve performance, we could cache the string representation of 
            the name, and reuse that as long as the identity stayed constant.  
            Once the identity changed, we would need to re-assign and re-render 
            the string.
            </p><p>
            However, the <span class="code">WindowsIdentity.GetCurrent()</span> call seems to 
            return different objects every time, so the current implementation 
            doesn't do this type of caching.
            </p><p>
            Timing for these operations:
            </p><div class="tableSection"><table><tr><th>Method</th><th>Results</th></tr><tr><td><span class="code">WindowsIdentity.GetCurrent()</span></td><td>10000 loops, 00:00:00.2031250 seconds</td></tr><tr><td><span class="code">WindowsIdentity.GetCurrent().Name</span></td><td>10000 loops, 00:00:08.0468750 seconds</td></tr></table></div><p>
            This means we could speed things up almost 40 times by caching the 
            value of the <span class="code">WindowsIdentity.GetCurrent().Name</span> property, since 
            this takes (8.04-0.20) = 7.84375 seconds.
