Why My PC can't be upgraded to Windows 11 25H2?

Your PC can't upgrade to Windows 11 25H2 primarily because of hardware compatibility requirements set by Microsoft for Windows 11. Based on the information you provided, the most significant factor is the absence of TPM 2.0, which is a key requirement for Windows 11 updates, especially for newer feature updates like 25H2.

Possible Solutions if can't upgrade to Windows 11 25H2:
1. Check Windows Update Settings:
    Sometimes, updates are rolled out gradually.
    You can use the Windows Update Troubleshooter or manually check for updates.
2. Use the Windows 11 Installation Assistant:
    Download the Windows 11 Installation Assistant.
    It can force the upgrade, but it will still check for hardware compliance.
    If your PC is blocked due to hardware, the tool might still warn or prevent installation.
3. Bypass Hardware Checks (Not Recommended):
    Advanced users sometimes modify registry or use tools to bypass TPM and CPU checks.
    Risks: Potential instability, security issues, and unsupported scenarios.
    Method: Use scripts or modify registry keys like AllowUpgradesWithUnsupportedTPMOrCPU.
4. Add a Fake TPM 2.0:
    Some users add a virtual TPM or modify the registry to trick Windows into thinking TPM 2.0 exists.
    This is complex and can cause security issues.
