Like we mentioned before, the MS Office product key is required to activate the suite of tools in the suite. While you may be able to download MS Office 2013 for free, you will not be able to activate and use it without a product key. This is how Microsoft ensures that you are using the genuine product and that you purchased the program you are using.
You can download Microsoft Office 2013 from the website free of charge, although it is important that you make sure you download the program from the official Microsoft website since files download online can pose a security threat for your computer. No matter where you get Microsoft Office 2013 though, you will still need to provide the genuine product key to activate the program. 2b1af7f3a8
