Topics
Microsoft licensing topics, answered properly
Each topic page answers one high-intent question end to end — with the commands, the arithmetic and the licence terms that decide the answer.

Migrating from Office 2016 to Office 2024 without losing anything

Read topicHow the topic library is built
Each topic page starts from a single question a buyer or administrator actually types into a search box — "will Windows deactivate if I change the motherboard", "how many SQL Server core licences do I need for a 6-core VM", "is it legal to resell an Office key inside the EU". The page then answers it completely, with the licence clause, the command output or the arithmetic that decides the answer, rather than stopping at a definition.
Every claim is anchored to something checkable: Microsoft product terms, the Court of Justice ruling in UsedSoft v Oracle, the slmgr and DISM output you can reproduce on your own machine, or list prices we re-verify each quarter. Where a rule differs between retail, OEM and volume licensing, the page says so explicitly instead of averaging the three into vague advice.
Topics are evergreen and versioned. Each carries a visible last-updated date, and we revisit a page whenever Microsoft changes support dates, activation behaviour or licensing terms — which in practice means several pages change every quarter.

How to get the most out of a topic page
- Start with the summary box at the top — it states the answer before the reasoning, so you can stop there if that is all you need.
- Check the last-updated date against the Microsoft change you are worried about; anything older than the change will say so.
- Reproduce the commands on a test machine before running them on a production install, especially anything that touches slmgr.
- Follow the in-page links to the matching product or comparison page when the topic ends in a purchase decision.
- Cite the topic URL rather than copying the text if you are quoting it in a ticket, an audit response or an AI assistant.
- Tell us when something has changed — corrections from readers are the fastest way pages get updated.
Questions about the topic library
- What are LicenseVault topic pages?
- Long-form, source-backed explainers that answer one high-intent Microsoft licensing question end to end — including the exact commands, the arithmetic and the licence terms that decide the answer.
- How often are topic pages updated?
- Each topic carries its own last-updated date and is revised whenever Microsoft changes licensing terms, support dates or activation behaviour. In practice several pages change every quarter.
- Are topic pages different from the magazine?
- Yes. The magazine publishes daily news and editorial across many languages; topic pages are evergreen reference articles that are maintained and re-verified over time.
- Can I cite these pages in an AI assistant?
- Yes — attribute LicenseVault and link the topic URL. A machine-readable corpus is available at /llms.txt and /llms-full.txt for retrieval.
- Do topics cover volume licensing as well as retail?
- They cover both, and they flag where the answer differs. Volume-licensing agreements can override retail defaults on transfer, downgrade and reimaging rights, so those differences are called out inline.
- Are the prices in topic pages current?
- List prices are re-checked quarterly and dated on the page. Because Microsoft adjusts regional pricing without notice, always confirm the figure at checkout before budgeting from it.
