What is the “upgrade version”?

This means that the OS can be upgraded (changed to a higher version) only if it is already running a Windows OS.
If your PC already has a Windows OS when you buy it, you are eligible.
In the case of a Mac, the upgrade can be applied as an OS that runs on virtual environment software or boot camp that can run on a Mac.
Downgrading the OS is also possible, but not recommended.

Counting when using virtualization.

Regarding virtualization at the client OS, up to four virtual OSEs are allowed per license per terms of the Software Assurance (SA) privilege.

How are CALs counted?

A Client Access License (CAL) is a license necessary for accessing a certain Microsoft server.
※Eligible users of the EES contract are granted the following types of CALs:

  • Windows Server CAL
  • Exchange Server Standard CAL
  • SharePoint Server Standard CAL
  • System Center Configuration Manager CML

NOTES:
For “Remote Desktop Access to Windows Server (RDS CAL)”, see eesq22.
Other licenses not listed here (such as the Exeternal Connector License) are not included in the EES contract.
CALs that are not included in the EES contract should be purchased by your organization, and you may be able to purchase CALs at a slightly lower price by informing the vendor that the University has an EES contract.

Is there RDS (Remote Desktop Services) here?

Our university has an RDS license.
You can set up a Windows Server on campus and take advantage of it if you need an RDS license (when you need remote desktop access).
This license expires in March 2028.

Precautions:
This license is for the faculty and staff of this university. A separate license is required for access by students and people outside the university.

Remarks:
This license can be applied to the access of the management company when the management work is outsourced to an off-campus company.
