how to unlock the document?

how to unlock the document

I tried to edit my document in the microsoft word but it states "this
modification is not allowed because the document is locked"

I don't remember locking it but all my documents are somehow locked.

So, can anyone tell me how to unlock so that I am able to edit my word.

Maybe you have a trial version of Office 2003 or 2007, and the trial
period has ended. Or maybe you have not activated your Office software.

What happens if you start Word 2003 and click on Help | Activate
Product, or if you start Word 2007 and click on Office Button | Word
Options | Resources | Activate? If you are already activated, a dialog
box saying so will appear. If you are not activated, the Activation
Wizard will start. If you have an expired trial version, a dialog box
will prompt you to enter a valid product key or convert (purchase a key)
online.
