Windows 10 – End of Support

Why This Update Matters

Microsoft will stop providing security updates, bug fixes, and technical support for Windows 10 on October 14, 2025. After that date a Windows 10 PC becomes far more vulnerable to malware and other attacks. The safest path is to move to a supported operating system—most users will choose Windows 11.

Key Windows 11 System Requirements

1. CPU (Processor)

  • Minimum: 1 GHz or faster, ≥ 2 cores.
  • But the CPU must be on Microsoft’s approved‑CPU list. Even a fast, dual‑core chip can be rejected if it’s not on that list.

2. Firmware – UEFI + Secure Boot

  • Old BIOS systems won’t work. The PC must use the modern UEFI (Unified Extensible Firmware Interface) firmware.
  • Secure Boot, a feature of UEFI that only lets trusted OS loaders start, must be enabled.

3. TPM 2.0 (Trusted Platform Module)

  • TPM 2.0 is a small crypto‑processor that stores keys and helps verify the integrity of the boot process.
  • Most computers made after 2016 include it, but it can be disabled in the BIOS/UEFI settings.

How to Check Your PC Today

Microsoft provides a free utility called **PC Health Check**.

  1. Open the Windows 10 search bar and type “PC Health Check”. If it appears, launch it.
  2. If it’s missing, download it here: https://aka.ms/GetPCHealthCheckApp.
  3. Click the **Check now** button. The app will tell you which (if any) requirements you’re missing.

What to Do If Your PC Fails the Check

  • CPU not on the list? You’ll need a newer processor or a new computer.
  • UEFI/Secure Boot disabled? Re‑boot, enter the firmware settings (usually F2, Del, or Esc during startup), and enable UEFI mode and Secure Boot.
  • No TPM 2.0? Some newer motherboards have a TPM header you can add a module to; otherwise you’ll need a newer system.
  • If fixing the hardware isn’t practical, consider purchasing a new Windows‑compatible PC. Look for a model that advertises “Windows 11 ready”.

Quick Upgrade Checklist

  • ✔️ Run the PC Health Check app.
  • ✔️ Verify your CPU is on Microsoft’s approved list.
  • ✔️ Ensure firmware mode is UEFI and Secure Boot is ON.
  • ✔️ Confirm TPM 2.0 is present and enabled.
  • ✔️ Back up your important files (external drive or cloud) before any OS change.
  • ✔️ If any step fails, decide whether to upgrade hardware or replace the PC.

Next Steps After the Checklist

When your machine passes all three requirements, you can upgrade to Windows 11 directly from Windows 10 Settings → Update & Security → Windows Update. If you run into errors, let us know—there are often simple work‑arounds (e.g., enabling TPM via the BIOS) that a technician can walk you through.
