A question that may had troubled, or is troubling some of you is: “When was my Windows installed ?”
There is a very easy way to find out:
1. Go to Start / type: CMD / Press Enter ( or Start / Run for previous Windows versions, prior to Win7 )
2. A command promt window will appear
3. Type: systeminfo | find /i “install date” / press enter
And if you encounter any problems feel free to comment / contact me.
