Windows 10 November Update

Windows 10 November Update (also known as version 1511 and codenamed "Threshold 2") is an update for Windows 10 which was released on 12 November 2015. It is a relatively minor update to the original release of Windows 10. It contains memory management improvements (included in Insider preview builds starting from build 10525), improvements to the overall UX and numerous enhancements to Microsoft Edge. The final build of the Windows 10 November Update (build 10586) was released to Insiders on 5 November 2015, and made available for consumers on 12 November 2015.

It was the first feature update for Windows 10 and it introduced the version number which was in the YYMM scheme where the first 2 digits are the year the update was released and the last 2 digits are the month in which the update was finalized. This would be used up until the May 2020 Update as Microsoft would then adopt the Azure YYHx numbering scheme as the version number for future updates, starting with the October 2020 Update (version 20H2).

This version is also the first to have an RTM build number that cannot be divided by 16, which was a requirement starting with Windows Vista. This also means that the post-period number no longer needs to be 16384 or later.
