Windows 10 build 10036

This build was a candidate for release to Windows Insiders, however, due to a few major bugs that seriously affected usability, Microsoft decided that it would not be released. These bugs include (but are not limited to):


 * The People, Mail, and Calendar apps will not open on this build.
 * In some cases, opening a folder on the Start Menu with sufficient items within it, and then closing it again, will cause Start to crash and fail to open again for several minutes.

This build is the first build to be either released or leaked publicly to include a semblance of transparency, as shown below.

The x64 Pro compile was leaked on 2015-03-14 to OSBetaArchive.
