Enabling Verbose MSI Logging

MSI logging can be expanded beyond installs and uninstalls.  It can also record any MSI action, such as repairs or self-heals.  Setting up a system policy to enable MSI logging can do this.   Since policies are presented locally as registry entries, use these steps to do it:

1. Launch Regedit and navigate to HKLM \Software\Policies\Microsoft\Windows\Installer.
2. Create a REG_SZ value named Logging.
3. Set the data to voicewarmup
4. Done.
