Windows 10 reached end of support on October 14, 2025, triggering the largest enterprise device retirement in a decade. Most organizations finished the replacement side months ago. The retirement side is a different story: in a remarkable number of environments, the displaced fleet went to storage, not disposition.
Replaced is not retired. Those machines still hold corporate data with none of the protections of a managed endpoint, their secondary-market value erodes with every quarter the surplus persists, and the inventory line that says 'storage' is an unanswered question in your next audit.
Finishing the job means moving the stored fleet through certified disposition — bulk sanitization or destruction with serialized certificates, remarketing the units that still have market value, and closing the inventory loop so the refresh project is actually, evidentially done.
If the answer is a storage room, the disposition half of the project is still open — and the resale clock is running.
