SkyDrive
All the SkyDrivePagesTest from 9431 are still present in this build and seem to work more-or-less the same.

Legacy F12 tools
Unfortunately, there is no way to return to legacy F12 tools in this build's Internet Explorer. It seems they were completely removed in this build.

This build has most of the registry settings of previous builds and some new ones.
