<p style="margin-top: 0px; margin-bottom: 10px;">Both halves of one Windows workstation in a single purchase: the operating system and the Office generation Microsoft supports on it, for a PC that keeps its documents and databases locally.</p>
<p style="margin-top: 0px; margin-bottom: 10px;"><strong>Microsoft Windows 10 Professional</strong> – The operating system plus BitLocker drive encryption, Hyper-V, Windows Sandbox and Remote Desktop host access. Those four are among the capabilities Windows 10 Home does not offer, and none of the Office applications are part of Windows.</p>
<p style="margin-top: 0px; margin-bottom: 0px;"><strong>Microsoft Office 2019 Professional Plus</strong> – Word, Excel, PowerPoint, Outlook, OneNote, Publisher and Access as installed desktop programs, with Skype for Business as part of the suite. Access and Publisher are among the applications the consumer Office 2019 editions leave out; Microsoft Teams is not included at all.</p>
