Upgrade from downgrading to Windows 8.1
Upgrade from downgrading to Windows 8.1
You might need to wait until Windows 10 reaches its end-of-life date, which is typically around June 2024, depending on the version. Even if you're using a Windows 8.1 license, continuing to use Windows 10 could involve ongoing costs for support or upgrades.
That sounds frustrating. Using a Windows 10 ISO with an older Windows 8.1 key might not be compatible.
