Are there big changes in Windows 11 24H2? I followed a couple of suggestions, including the registry hack and unable to install Windows 11 without secure boot on an old Dell laptop. In fact, I am a long time Mac user and want to give a try on Windows 11 first before buying a Windows 11 fully compatible device, which is not cheap now.
There are very less guides available for installing Windows 11 24H2 on unsupported hardware. Anyone in this community knows how to fix this? If I am fine with the Windows 11 on this legacy Dell laptop, I could definitely build a new PC and switch to Windows 11 from Mac.

When using installation media or installation assistant, simply unpack the ISO, go into the “Sources” folder, then edit the “appraiserres.dll” file to be empty. This cripples the requirements detection program and allows the installation to proceed normally on anything.

Zung Hoang 0 Reputation points2025-07-03T20:37:47.4466667+00:00 Here is how to Bypass TPM 2.0 and Secure Boot:
- Download the latest Windows 11 ISO file.
- Extract the contents of the ISO file.
- Open the "sources" folder and copy the file named "setupprep.exe".
- Paste it as a shortcut (Right-click in an empty area → Show more options → Paste shortcut).
- Right-click the shortcut you just created and select "Properties" (or press "Alt + Enter").
- In the "Target" field, add " /product server" (including the leading space), then click "OK".
- Launch the "setupprep.exe - Shortcut" to upgrade to the latest Windows 11.
Alternative Method Using Command Prompt:
- Run Command Prompt (cmd) as an administrator.
- Navigate to the "sources" folder using the command:
cd C:\Extracted Folder\sources - Type the following command and press Enter to start the installation:
setupprep.exe /product server
Hope that helps you! 😊
