Quick one – I’m doing some testing in my home lab environment with Windows 11 and this box doesn’t have a TPM (so it’s not enabled in Hyper-V). Booting up the Windows 11 iso and trying to install will tell you that it’s unsupported. To get around that, load the setup as normal and once you reach the language and time screen press Shift+F10 to bring up the command prompt. Type regedit and hit enter to launch Reg Edit for the pre-install environment. Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\Setup registry hive and create a new Key called LabConfig. Now under LabConfig create two DWROD (32-bit) values, one BypassTPMCheck and the other BypassSecureBootCheck and set both of these to a value of 1. If you don’t have enough RAM allocated you can also add a DWORD of BypassRAMCheck and value of 1.
Once you’re done close up Regedit and the Command Prompt and you can start the setup process and install as normal.
