Windows 10 build 10036

Windows 10 build 10036 is a build of Windows 10. The build was originally selected as a candidate by Microsoft to be released to Windows Insiders, but was not made public due to a number of bugs that severely impacted the usability of the operating system. It was eventually shared on OSBetaArchive on 14 March 2015.

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 applications fail to launch in this build.
 * Opening a folder on the Start menu with sufficient items within it and then closing it again will cause its backend to crash, preventing access to the Start menu for specified period of time.
