Here’s a trick you can use to find out when Windows XP was installed. Open a command prompt (”Start” > “Run” > type: cmd), and type this at the prompt:

systeminfo | find /i “install date”

You can also simply type this in the Run command box:

cmd /k systeminfo | find /i “install date”

The systeminfo comand is filtered by the find command, which then displays the text containing “install date” and displays anything that matches.
