This release focused on polishing the initial Windows 10 experience. It improved the Start menu, made Cortana more usable without a Microsoft account, and fixed a large number of early bugs.

What changed in 1511

  • Start menu could show four medium tiles in a column
  • Context menus and right-click options for Start items improved
  • Cortana could be used without signing in with a Microsoft account
  • Visual refinements and less harsh default styling
  • Better overall stability compared with the original 1507 release
  • Messaging and Skype integration updates

Edge still lacked extensions at this stage, and some users continued to report browser bugs and general rough edges. Enterprise LTSC was not offered for 1511, and language packs were more limited than in later releases.

These are the original November 2015 Update images. If you need a Windows 10 installation that remained supported the longest, use the final release: version 22H2.

How to install

Create a bootable USB with Rufus or the Media Creation Tool, boot from it, and choose either an upgrade or a clean install. After Windows finishes the initial setup, run Windows Update to install any remaining cumulative updates that were still published for 1511.

Mounting the ISO and running setup.exe also works for an in-place upgrade.

Notes

  • Windows 10 reached end of support on 14 October 2025. Version 1511 stopped receiving regular updates years earlier.
  • A genuine product key matching the edition is required for activation.
  • For any new installation today, prefer 22H2.
