Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I have just removed the demo copy of Office 2007 preinstalled on a new laptop and replaced it with an install of the full professional edition downloaded from the MS Volume Licensing site and installed one of our volume licence keys, yet the apps (Word etc.) show "Non Commercial Use" in the title bar, which is what usually happens in the Home and Student edition.

I have tried:

  • Deleting the Office registration keys in the registry and using one of our other Office 2007 volume licence keys (we have 7) when prompted to re-register

  • Uninstalling Office completely and reinstalling it from a newly-downloaded ISO burned to CD and also from a compressed file that installs from hard disk/USB stick (both from Microsoft - no dodgy stuff)

Yet the non-commercial message persists. Although it's a cosmetic issue, the laptop is going to be used for customer presentations and so the sales person is rightly concerned about the image this portrays.

I presume there may be something floating around the registry or in a file somewhere but I can't find it. Articles I have found elsewhere just refer to the message being related to the use of a Home and Student licence key, which is 100% not the case.

Any thoughts? Thanks.

Well, problem solved: it seems there was another installed instance of Office 2007 helpfully called '2007 Microsoft Office System' so it sat at the top of the list of software in the Control Panel rather than among the entries for "Microsoft...." applications. Once this was removed and Office 2007 'proper' removed and reinstalled (again) the problem went away.

I'm going with the demo wasn't completely removed. As to a specific reg-key no idea, but I would try whatever registry cleaning utility you prefer to try and clean up dangling reg-keys.

Linker 3000 is right, there was a pre-installed Hybrid version (trial) by the name 2007 Microsoft Office System (650mb). After I uninstalled it, the line Non commercial use vanished from title bar of Word 2007 & other Office 2007 Enterprise edition programs.

In this registry fixing doesn't work as Office reconfigures the registry at each launch. Many of them are asking this Q. Unlike Microsoft's answer ('it must be home/student version') this is the correct solution.
