This stands for Professional Plus.
It is the top-tier edition for volume licensing. It includes the core heavy-hitters: Word, Excel, PowerPoint, Outlook, Publisher, and Access.
Note: Unlike Microsoft 365 Apps for enterprise, this ProPlus version does not include OneNote (the 2016 desktop version is often bundled separately) or the full Outlook mobile sync features.

What is Office LTSC 2021?

LTSC stands for Long-Term Servicing Channel. Unlike Microsoft 365 Apps, which receive new features monthly, LTSC versions are locked in time. They receive only security updates and critical bug fixes for five years (mainstream support) plus an optional additional period. Legitimate Acquisition: Where to Get This ISO Warning:

Key characteristics of LTSC:

No feature updates – The software you install today will look and work the same in 2026.
Perpetual license – Pay once, own it forever (for that specific version).
Stability-focused – Ideal for regulated environments, manufacturing floors, and users who despise UI changes.
No cloud dependencies – Does not require a Microsoft 365 subscription (though activation needs occasional internet).
