Like the Windows Insider program, the Office Insider program is an ongoing preview program for Office 365 subscribers (both Windows and Mac), providing early access to the latest Office features. It's open to anyone who has an Office 365 subscription (administrators need to enable First Release on business accounts before business users can install the Insider Builds).
If you want to file bug reports, you'll need to "upgrade" to an Insider build. Then you can go to File, Support, Contact Support. I highly recommend doing this if you feel a behavior is a bug.
Monthly Channel (Targeted) is the original Insider program. Users in this ring will receive an update about a week before the official production release each month, and then the official production release when it goes out (2 updates per month). These two are generally very close in terms of features and fixes.
Office Insider is a new level that delivers weekly updates from the development branch. There will be features available to users in the Insider ring that won't be available to Monthly Channel (Targeted) or Production. Because this build is from the development branch, these users always be a version ahead of the official production release.
You can check to see which update channel you are currently using in File, Office Account (or Account in Word or Excel). The update channel is listed below the suite name and the version number.

If you'd like to join the Office Insider program and have a consumer subscription (Home, Personal, or University subscription) go to the Additional Install Options page of My Account and choose an Insider option from the Version drop-down menu.
Office 365 business and enterprise users get the Insider Build through First Release program. To switch from Insider Slow to Insider Fast, you'll need to set the following registry value:

To choose one of the other update channels, use Value in the first column in the updatebranch, instead of InsiderFast.

Thanks so much. I was looking for this... a load! I was looking around, everywhere to see how to install Office if your with a school. This is a great tutorial: and it works. The registry links work because Office is downloading for me now. Great work!
