To enroll your PC in the ESU program, you'll need to meet Microsoft's list of requirements and anti-requirements, which we'll summarize here for convenience:

• A PC running Windows 10 Home, Pro, Pro Education, or Workstation with all available update installed.
• An administrator account.
• A Microsoft account. Even if you usually sign in with a local account, you need a Microsoft account to acquire the ESU license.
• The PC can't be in kiosk mode, joined to an Active Directory domain, joined to Microsoft Entra, or enrolled in any kind of mobile device management (MDM), which will cover a lot of workplace PCs. Microsoft has separate ESU programs for businesses, schools, and other large organizations.

If your PC meets those conditions, you'll enroll in the ESU program by opening the Settings app and clicking Windows Update. You should see a status message telling you that Windows 10 updates end in October of 2025, with an "enroll now" link you can click to enroll in the Extended Security Updates program.
