Windows 10 Extended Security Updates: Year 1 ends

Windows

Who is affected

Organisations whose Windows 10 Enterprise, Education or Pro (commercial use) devices were covered only by Year 1 of ESU. Without Year 2, those devices stop receiving security updates.

What to do

1. List Windows 10 devices still in use and confirm which ones have a Year 2 ESU key activated.
2. Buy Year 2 for devices that cannot move yet; ESU is cumulative, so a late start still pays for Year 1.
3. Prioritise upgrading or replacing the devices that have no ESU coverage.
