Windows 95 build 456

This build is an interim build released to testers in late April/early May 1995. Internally, it is also known as an 'April Test Release' build.

New Features

 * This build re-introduces the mandatory upgrade requirement from build 420 in its Setup program. You can no longer get past it by using the install disks of an earlier Windows version.
 * It introduces a new, abstract style for the billboards used during Setup. This style was used until build 480.
