Each Office Professional Plus 2010 program is asking to be Activated. Where is the Activation key now the computer has changed companies and locations? Can this be done by phone?

Hi,

Regarding of this issue, I have a couple of questions:

1) Was Office 2010 pro plus deactivated after installed Windows 10?

2) According to your description,>>Where is the Activation key now the computer has changed companies and locations?<< Did you migrate this pc that installed Office Professional Plus 2010 to a new company and location?

As far as I know, Office Professional Plus 2010 is usually using Volume License. I recommend you connect the Microsoft Volume License service center to get more help.
