Windows 10 build 10138

Windows 10 build 10138 is a build of Windows 10.

History
This build has potentially the most bizarre leak method for any Windows build. On 2019-06-28, BetaWiki Discord user lucasm uploaded a 7z file with a password added called "payrespects.7z", containing a x64 Pro ISO of this build. The password then had to be guessed by other users of the BetaWiki Discord, with lucasm giving hints. Applegame12345 was the first user to find the password and install the build. Windows 10 build 10143 was also leaked via a similar 'game' two days later.
