Hi, I am an Independent Advisor, and welcome to Microsoft Q&A.
I understand that the link to purchase ESU does not appear on your PC update screen.
Please make sure that the prerequisites have been met.
"Prerequisites
To enroll in the consumer ESU program, make sure your device meets the following requirements:
- Devices need to be running Windows 10, version 22H2 Home, Professional, Pro Education, or Workstation edition
- Devices need to have the latest update installed
- The Microsoft account used to sign in to the device must be an administrator account
- The ESU license is tied to your Microsoft account, so you may be prompted to sign in if you typically sign into Windows with a local account
- The Microsoft Account can’t be a [child account](https://support.microsoft.com/en-us/account-billing/managing-parental-consent-c6951746-8ee5-8461-0809-fbd755cd902e)"
- The ESU license is tied to your Microsoft account, so you may be prompted to sign in if you typically sign into Windows with a local account
If the above requirements have been met, please wait for the rollout. It is now gradually rolling out to all Windows 10 users who are running the required updates or the latest updates. If you still do not see the enrollment options, it only means that this has not reached you yet, but it will, eventually.
