How you open your system properties dialog box?. By right clicking on My Computer icon and then select properties or by selecting system icon from control panel. Tell me truly that this is killing your time [On Very small scale but you surely heard this that "Time is money"] so why are wasting your cents of time just press windows logo key and pause/break key together and boo! here your system properties comes![pause/break key is near from your Num Lock key. Locate it!]
Have fun!
