Windows 10 build 10036

Windows 10 build 10036 is a build of Windows 10. It 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. It eventually leaked on 14 March 2015 to OSBetaArchive.

New features

 * The new upgrade screen has been introduced, although it says "Installing Windows" instead of "Upgrading Windows" like the RTM.

Bugs

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