If your PC can't be upgraded to Windows 11, it fails to meet one or more minimum system requirements; use the PC Health Check app or third-party tools like WhyNotWin11 to identify the specific issue. 2. Most commonly, the problem is TPM 2.0 or Secure Boot being disabled, so access BIOS/UEFI settings and enable both features to resolve the issue and proceed with the upgrade.

If you're seeing the message "This PC can't be upgraded to Windows 11", it means your device doesn't meet one or more of Microsoft's minimum system requirements. But don't panic — in many cases, you can still fix or work around the issue. Here’s how to diagnose and resolve it.

? 1. Check Why Your PC Doesn’t Qualify

The first step is to find out which requirement your PC is failing. Microsoft lists several key hardware requirements for Windows 11:

• 64-bit processor with 1 GHz or faster (2 or more cores)
• 4 GB RAM or more
• 64 GB or larger storage
• UEFI firmware with Secure Boot support
• TPM 2.0 (Trusted Platform Module)
• DirectX 12-compatible GPU with WDDM 2.0 driver
• HD display (720p or higher, 9” or larger)

To check compatibility:

• Use PC Health Check app (download from Microsoft).
• Or use third-party tools like WhyNotWin11 or Win11UpgradeCheck.

These tools will tell you exactly what’s missing — most commonly TPM 2.0 or Secure Boot.

? 2. Enable TPM 2.0 and Secure Boot

Even if your PC supports TPM 2.0 and Secure Boot, they might be disabled in BIOS/UEFI.

How to enable them:

1. Restart your PC and press the BIOS key (usually F2, F10, DEL, or ESC) during boot.
2. Navigate to Security, Advanced, or System Configuration.
3. Look for:
   • TPM / Security Device / PTT (Intel Platform Trust Technology)
   • Secure Boot
4. Enable both (if available).
5. Save and exit.

? On many Intel-based systems, TPM 2.0 is called Intel PTT. On AMD, it’s often AMD fTPM. Make sure it's set to Enabled and TPM 2.0, not 1.2.

After enabling, re-run the Windows 11 compatibility check.

?? 3. Ensure UEFI and GPT Disk Mode

Windows 11 requires:

• UEFI boot mode (not Legacy BIOS)
• GPT partition style (not MBR)

To check:

• Press Win R, type msinfo32, and press Enter.
• Look for:
  • BIOS Mode: Should say UEFI
  • Disk Partition Style: Should say GPT

If it shows Legacy or MBR, you’ll need to convert.

?? Converting from MBR to GPT or Legacy to UEFI may require reinstalling Windows unless you use tools like MBR2GPT (available in Windows 10 1903 ).

To convert safely:

• Open Command Prompt as admin.
• Run:

  mbr2gpt /validate /disk:0

  If valid, then:

  mbr2gpt /convert /disk:0

• Then enable UEFI in BIOS.

? 4. Upgrade or Bypass (If Hardware Is Close)

If your PC is almost compatible (e.g., has TPM 1.2 instead of 2.0), you might still upgrade — but not officially supported.

Option A: Registry Bypass (Not Recommended Long-Term)

Microsoft allows some bypasses during upgrade, but they may break future updates.

You can edit the registry to skip checks:

1. During setup, when blocked, press Shift F10 to open Command Prompt.
2. Type regedit
3. Go to:
   HKEY_LOCAL_MACHINE\SYSTEM\Setup
4. Create a new key: LabConfig
5. Inside it, create these DWORD (32-bit) values:
   • BypassTPMCheck = 1
   • BypassSecureBootCheck = 1
   • BypassRAMCheck = 1
   • BypassStorageCheck = 1
   • BypassCPUCheck = 1
6. Close Registry Editor and go back to setup — it should now proceed.

?? This works for clean installs only and may cause instability or prevent future updates.

Option B: Clean Install Using ISO

Download the Windows 11 ISO from Microsoft.

• Create a bootable USB (using Rufus or Media Creation Tool).
• Boot from USB and install.
• Use the registry bypass trick above if blocked.

This method skips the in-place upgrade check.

? 5. When You Can’t Fix It

Some older PCs (especially from before 2018) simply don’t support required features like TPM 2.0 or UEFI.

In that case:

• Stick with Windows 10 (supported until October 2025)
• Consider Linux if you need a modern OS on old hardware
• Upgrade your hardware (e.g., new PC or SSD compatible motherboard)

Summary: What to Try First

• ? Run PC Health Check to see the exact issue
• ? Enable TPM 2.0 and Secure Boot in BIOS
• ? Confirm UEFI mode and GPT disk
• ? Try a clean install with bypass if necessary
• ? Accept that some PCs just aren’t meant for Windows 11

Most "unupgradable" PCs can be fixed with BIOS tweaks — especially enabling TPM and Secure Boot. If your hardware is too old, staying on Windows 10 is still safe and practical for now.
