How do I keep getting Windows 10 security updates?
Enroll in free Extended Security Updates (ESU) from Windows Update. Home PCs are covered until October 12, 2027.

Is Windows 10 still safe to use?
Yes, if it's enrolled in ESU and keeps installing updates. Without ESU it gets riskier every month.

Why isn't the Windows 10 ESU "Enroll now" link showing?
Usually the PC isn't on version 22H2, is missing updates, isn't signed in with an admin Microsoft account, or is linked to a work or school.

What do I do with Windows 10 after October 2027?

Can my PC run Windows 11?
Run Microsoft's free PC Health Check. PCs from 2018 on usually pass, and a TPM or Secure Boot failure can often be fixed in the BIOS.

Windows 11 24H2 support ended. How do I update?
Check your version with winver. If it says 24H2, install version 26H2 from Windows Update, or install it by hand on an unsupported PC.

Should I install Windows 11 on an unsupported PC?
It works with tools like Rufus, but updates aren't guaranteed. Fine for a spare PC, not the one you bank on.

Can a 7th-gen Intel PC run Windows 11?
Not officially, and no setting or processor swap changes that. Your options are ESU for now, Linux, a workaround, or replacing it.
