hi guys i need your help, i already installed Office 2013 on my PC, i lost the key,. so i like to know "How to find Office 2013 Key" by using a little software which can stay in USB then on one click i have to find out my key. I don't want to install any software to find out this key, but i want a little software which can stay in USB and when i click from USB then it have to find my Office 2013 Key. like in old days i use a key finder program, which will run from the USB and very eassly find the Product key. So can any body let me know a USB runnable software to find the product key of Office 2013. Thanks for your replies.
