Re: Extended Security Updates (ESU) program for Windows 10 purchasing options

Dear colleagues, 

Please see the information below regarding Extended Security Updates (ESU) purchasing options for Windows 10 users at U of T shared by the U of T License Software Office (LSO). 

Below is the current cost per year per device with a start date in November 2025. 

Year	Cost Per Device
Year 1	$1.90
Year 2	$3.70
Year 3	$7.40

Please note that ESUs are cumulative and purchasing a new license in year two requires purchase of a year one license. Purchasing a new license in year three requires purchase of a year two and year one licenses. 

Several departments within the university have already expressed interest in participating in the ESU program, and LSO will be canvassing others shortly to determine additional demand. 

The LSO is coordinating a bulk purchase. Please contact them at lic.software@utoronto.ca to let them know how many licenses your department is interested in purchasing.

If you have any questions or concerns, please reach out to the License Sofware Office (lic.software@utoronto.ca).
