Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Jerry,
The first is the general release number, shared among Word 2016, Word 2019, and Office 365. 2005 indicates the fifth month of 2020. The next one is the full numbering including the bit-ness and which actual product you have.
