Common Questions

Is Windows 8.1 still safe to use? Not for internet-connected systems. Without security updates, any newly discovered vulnerabilities won't be patched. Use only in isolated, controlled environments.

Can I upgrade from Windows 8.1 to Windows 10 or 11? Yes, but you'll need a separate Windows 10 or 11 license. The free upgrade period ended years ago.

Why would anyone buy Windows 8.1 in 2025? Legacy software compatibility. Some specialized business applications, medical equipment software, or industrial control systems only work on Windows 8.1.

Will my old Windows 8.1 PC run Windows 10? Most Windows 8.1-compatible hardware runs Windows 10 fine. Windows 11 has stricter requirements (TPM 2.0, newer CPUs).

What's the difference between Windows 8.1 Standard and Pro? Pro adds BitLocker encryption, Remote Desktop hosting, domain join capability, Hyper-V virtualization, and Group Policy management.
