Changing the text on the Computer icon on your Remote Desktop Services Session Host is handy when a user calls you and you want to know which Session Host the user is logged on. The procedure to do this has changed since Windows Server 2003.

Unfortunately, there is no Last Write Time associated with a registry value, but it can be infered from the Last Write Time of the key.
Here is a PowerShell script to read the Last Write Time for a registry key.
Usage:
Get-RegKeyLastWriteTime.ps1 <Key> <SubKey>
IP scanner for the poor ones

C:\>FOR /L %x in (1,1,255) do ping -n 1 192.168.2.%x | find /I "reply" >> c:\temp\pingresult.txt

Or the PowerShell version:
C:\> 1..255 | foreach-object { (new-object System.Net.Networkinformation.Ping).Send("192.168.2.$_") } | where-object {$_.Status -eq "success"} | select Address
