[SOLVED] Windows 10 Preview Build 9841 fails to upgrade to 9860

Today the first update to the Windows 10 preview came out.
When I tried to upgrade I got this error:
Failed to install the new preview build, please try again later. 0x80080005

My Windows 10 install is an upgraded Windows 8.1 PC that was updated from Window 8 RTM.  I have Visual Studio so I have many options turned on, like IIS. (Internet Information Server)
I installed the x64 Enterprise version from the ISO download.

This is the errors I got from the Event viewer after the upgrade failed 3 minutes into the upgrade:
