Here is a how-to guide for anyone interested in installing Microsoft Office on your personal device. In my case, I installed it on my personal Macbook but the process should be very similar for installing on a Windows machine.
If you go through the steps, you will have Office apps loaded on your machine without paying anything to Microsoft. You will even get a little personal OneDrive storage (5GB). Of course, if you want more storage, you can buy it from Microsoft.
First of all, here is the SAS policy Knowledge Base article KB0013415.
The current policy reads:
"Office 2016 is now part of Office 365, a subscription service available to all SAS employees. You can install Office 2016 on up to 5 machines (PCs or Macs), 5 tablets, and 5 smartphones and they can be a mix of business or personal. On a personal machine, you can install Office from http://office.com. Two-factor authentication is required."
