I purchased Office 2013 when it was first release, and was surprised to find out that under the terms of the user agreement I couldn't transfer the license from the machine on which it was originally installed to another machine without purchasing a new license. Not a huge deal, but we are a small business. Apparently I wasn't the only one that was unhappy about this, and MS apparently has changed their mind and allows limited transfers, which is fair. What I'm not sure of is whether this change applies retroactively to earlier purchases of Office 2013 such as mine. Anyone know?
