You have to  add a slave side command that can read the registry

Look at here for examples of slave-side commands: 
https://github.com/buildbot/buildbot/blob/master/slave/buildslave/commands/fs.py

A SlaveShellCommand can do that, then you need to save the env somewhere once the command have been executed

> 3.	execute msbuild_command

Again, a SlaveShellCommand, but only after having reinjected the env from the previous execution of vcvarsall.bat

Command are ordered by the master, for an example of 'Step' that runs multiple commands on the slave, you can look ... at the new source steps who runs multiple times the version control tool. Somewhere here: https://github.com/buildbot/buildbot/tree/master/master/buildbot/steps/source


Don't hesitate to ask if you have more questions.

Benoît.
