Microsoft Office 2010 Starter edition is a free, ad-supported version of Office 2010 meant to be included on new PCs. It only includes Word and Excel with a subset of features—but it does let you make a portable version. Here’s how to do it.
Update: looks like the link is dead.
Note: The download link provided in the following article is not exactly a “Microsoft Approved” link and may stop working at any time. Still, the Starter version of Office is meant to be ad-supported freeware, and they haven’t pulled the download despite widespread use of it online.
Creating Your Portable Office
The first thing you will have to do is grab a copy of Office 2010 Starter from this link. Once the download has finished, double-click on the file to launch the installation. The installer will attempt to download the actual files needed to install Office. Once it’s completed downloading, it will go through the installation—it’s really a very quick process.
Now that Office Starter is installed, head to the Start Menu, go to All Programs and open the Microsoft Office 2010 Tools folder, and then launch the Microsoft Office Starter To-Go Device Manager 2010—or you could just search for it in the Start Menu search box.
Again Office will now download more files.
Once downloaded you will be asked which drive you would like to install Office on.
Office will now be installed to your USB.
Once you see that the installation is complete your USB is ready to go.
If you open explorer you will see that your USB with Office on it has a nice new icon.
Office To-Go has a launch application on the root of the drive called Office.exe from which you can launch Word and Excel.
That’s all there is to it guys, enjoy your portable installation of Office 2010 Starter.
