How BypassTPMCheck-SecureBoot Works — Risks and Safe Alternatives

Quick guide — BypassTPMCheck & BypassSecureBoot registry method (installer-time)

Warning: bypassing TPM/Secure Boot reduces security and may affect updates. Back up your data and firmware settings.

Requirements: Windows 11 installation media (USB or mounted ISO), ability to open Registry Editor during setup (Shift+F10 → regedit).

Steps:

1. Boot the PC from Windows 11 installation media and reach the installer screen where language is chosen.
2. Press Shift + F10 to open Command Prompt.
3. In the Command Prompt type: regedit Enter to open Registry Editor.
4. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\Setup
5. Right-click the Setup key → New → Key. Name it: LabConfig
6. With LabConfig selected, right-click in the right pane → New → DWORD (32-bit) Value and create these values (set each to 1):
   • BypassTPMCheck = 1
   • BypassSecureBootCheck = 1
   • (optional) BypassRAMCheck = 1
7. Close Registry Editor and Command Prompt, continue the installer. The hardware checks should be skipped and installation proceed.

Notes and alternatives:

• Some installers/versions ignore LabConfig; alternatives include using updated Rufus, Patchium/SetupPatch tools, removing requirement-check DLLs (appraiserres.dll) in the ISO, or running setup.exe with compatibility switches when upgrading from within Windows.
• After install, consider re-enabling Secure Boot/TPM in firmware where possible and monitor Windows Update behavior.
