Microsoft Office 365
Every Staff member and Student have access to Office 365. The current license allows for 2 computers to have the software installed.
To manage installation on a school imaged laptop you need to use the Managed Software Centre to install and remove the software.
This does not control the software activation. Activation is controlled using your school email address to both activate and deactivate computers.
You can manage your account by going to
https://portal.office.com/account/
Don't try to install Office on a school imaged laptop, again use the MSC. You can install the software on a non-imaged computer via this website https://portal.office.com/OLS/MySoftware.aspx (you need to be signed in to access this site).
This video shows you the de-activation process.
