Microsoft is ending support for Windows 10 version 1909 on May 11, 2021. This applies to:

  • Windows 10 Home

  • Windows 10 Pro

  • Windows 10 Pro Education

  • Windows 10 Pro for Workstations

If you have one of the listed editions of Windows 10, it is strongly recommended and encouraged that you update it to the latest version (Windows 10 v20H2) before May 11, 2021 to continue receiving Windows updates and Security updates from Microsoft.


Please note:

  • Backup your system before doing your Windows Update. Berkeley Lab IT offers Druva inSync for backup solutions

  • Update files can be big and may take several hours to download

  • While Windows Update is downloading updates, you can minimize it and continue working

  • When the download is complete it will ask for a reboot. We suggest delaying until the end of the day, as your system will be unusable during the updates.

  • Additional updates may need to be applied after you reboot and login. It may take up to 30 minutes to apply settings before the next updates can be applied. On some rare occasions, it could be longer than 30 minutes. This process may need to be repeated multiple times until Windows is completely up to date.


Not sure how to do the update? See Run Windows Update for Windows 10.
