Office Web Apps problems with 100% CPU

I had a problem trying to use Office Web Apps with SharePoint 2010 on a virtual machine demo.  On a simple Word document, the AppServerHost.exe service would jump to 100% and render the system unusable.

The problem is that Office Web Apps was not designed to be installed on a system that is also a domain controller (the case with my all-in-one virtual machine).



Here are the steps to fix the configuration:

Open SharePoint 2010 Management Shell, then run:

#Enable Word Web App (you can search by TypeName - language dependent or DisplayName - as it appears in SharePoint Central Administration)

$e = Get-SPServiceApplication | where {$_.TypeName.Equals("Word Viewing Service Application")}
$e.WordServerIsSandboxed = $false

#Enable PowerPoint Web App - you need to answer "Y" for each command:
Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedViewing $false

Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedEditing $false

On the server, use Notepad to open c:\windows\system32\inetsrv\config\applicationHost.config.  Add the line below at the end of the dynamicTypes section.
<add mimeType="application/zip" enabled="false" />
