Free tool · updated September 2026

Find out what in your Microsoft estate stops getting security updates

Add the Windows, Office, Server, SQL and Visual Studio versions you actually run. You'll get every end-of-support date, how long you have left, and a quarter-by-quarter migration order.

Build your estate

Add one line per product version. Seat or server counts are optional but sharpen the migration plan.

Nothing added yet. Start with whatever you know you're running — most estates have at least one surprise in them.

The dates above are the diagnosis. The report is the plan.

  • Every product dated, sorted into the quarter you need to act in
  • Whether paid Extended Security Updates exist as a fallback, and until when
  • The supported version to move each product to
  • A reminder email 90 days before each deadline, so nothing slips

Your report arrives in a few seconds. We never share or sell your address.

End-of-support dates are published by Microsoft and were verified on 6 September 2026 against Microsoft Lifecycle. Microsoft can amend dates and add Extended Security Update programmes — confirm against Microsoft's lifecycle page before committing budget. This tool gives planning guidance, not a licence audit.
