So I want to reset my laptop soon, because my hard drive is and I do not want to sort everything out. Now the question is how to read the key from Microsoft Office (Word, Powerpoint, Excel etc.) so that I can use these programs again afterwards
What is your hard drive?

Quadsoft Product Key Extractor… The program also reads out Office Keys in fair copy, it is freely available on the net
