For all those user's who always wanted to know where to find the Microsoft Office Key and why should everyone always treasure this. Here the link to show you what you should be looking for.
For starters without the key Microsoft nulls your rights as a registered user, in plan English "they just don't care". The reason why Microsoft does this is because they want you to buy the product all over again. For many people, they just have no choice but to do that.
That's why everyone should never take license keys for granted. You never know when your going to need them. You might one day have to re-format your computer or operating system and will have problems installing the software without the key.
If you already have a license product and somehow lost the key, just view my blog to find software that shows all the license Keys on your computer including Microsoft.
Remember to always save your product keys in a safe place.
