This Office 2021 Pro Plus and Windows 11 Pro bundle gives you two phone activation keys in one order: one for Microsoft Office 2021 Professional Plus and one for Windows 11 Pro. It is a special-offer way to set up a complete work PC, with the operating system and the full Office suite, at a fraction of the cost of buying them separately.

These are phone activation keys, so they do not activate automatically. Microsoft retired its telephone activation line in December 2025, and the same ID exchange now happens in Microsoft's online Product Activation Portal. You will need a free Microsoft account and a few minutes for each product.

Office 2021 is a one-time purchase version of Office. Microsoft ended support for it in October 2026, so it no longer receives updates, but the apps continue to work.
