How to upgrade Windows 11 24H2 to 25H2 without losing data?

1. Check for Compatibility
Use the PC Health Check app: Download from Microsoft's official site to verify if your device meets Windows 11 25H2 requirements.
Key requirements for Windows 11 25H2 may include:
* TPM 2.0 (your device has TPM 1.2; this may prevent official upgrade)
* Secure Boot enabled
* Compatible CPU (your 6th Gen CPU may not be officially supported)

Conclusion: Your hardware may not meet the official requirements, which can block the upgrade via Windows Update.

2. If your device is compatible or you choose to proceed
Note: Proceeding with unsupported hardware may cause stability issues. Consider this carefully.

3. Methods to Upgrade Windows 11 24H2 to 25H2
A. Use Windows Update (if the upgrade becomes available)
Go to Settings > Windows Update and check for updates.
If 25H2 is available, you'll see a prompt to upgrade.

B. Manual Upgrade via Media Creation Tool
Download the Windows 11 ISO for 25H2 from Microsoft
Use the Media Creation Tool or create a bootable USB.
* Run the setup from within your current Windows environment:
Double-click the ISO or run setup.exe from the mounted ISO.
Choose "Upgrade this PC now".
Follow prompts to upgrade Windows 11 24H2 to 25H2, ensuring "Keep personal files and apps" is selected.

This method upgrades without removing your data but always back up first.

4. Bypass Compatibility Checks
* Modify Registry to bypass TPM and CPU checks:
Warning: This is unsupported and may cause stability issues.
Before proceeding, back up your registry.
* Create a registry key:
Open Registry Editor (regedit)
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup
Create a new key: LabConfig
* Inside LabConfig, create DWORD values:
BypassTPMCheck = 1
BypassSecureBootCheck = 1
BypassCPUCheck = 1
Run the Windows 11 installation media setup again.
