Microsoft Changes Office Licensing Conditions

From The Age:

In the push to shift customers to the Office 365 subscription model, Microsoft has rejigged the licensing conditions on retail copies of Office 2013 such as Office Home & Student 2013. People tend not to read this sort of fine print, but this bit is kind of important.

According to the fine print, retail copies of Office Home & Student 2013 are now single-license, so you can only install them on one computer. Some people interpret this as meaning that the retail license is now similar to the OEM license, which covers copies of Office that come pre-installed on a new computer. Under an OEM license you can only run Office on that specific computer. If you buy a new computer, you can't uninstall that OEM copy of Office from your old computer and reinstall it on the new one.

You could transfer a retail copy of Office from your old computer to your new computer, at least you could until now.  If you read fine print, the licensing conditions have clearly changed between Office 2010 and Office 2013.
