So, where is it in Windows 11?

The short answer: Microsoft removed the legacy F8 menu and the classic LKGC feature years ago.

If you’ve been working with Windows for a long time—say, since the days of Windows XP, 7, or even 10—you probably remember a specific safety net. It was called Last Known Good Configuration (LKGC).

Stop looking for F8. Next time Windows 11 refuses to boot, hold Shift + Restart or just turn it off mid-boot twice. The blue recovery menu is your new best friend.

If you really miss the F8 menu, you can re-enable it via bcdedit /set {default} bootmenupolicy legacy in an admin command prompt. However, on NVMe SSDs and UEFI systems, you’ll still blink and miss the window.

Lab Setup

You can build your own lab as elaborate as you would like. However, for the purpose of this class, the following virtual machines (VMs) will be used.

This video explains how to setup the virtual machines in your system using Virtual Box.

Topology

The diagram below shows the lab architecture with WebSploit Full version, Raven, and VTCSEC. The VMs were created in Virtual Box. It is highly recommended that you use Virtual Box. However, if you are familiar with different virtualization platforms, you should be able to run the VMs in VMWare Workstation Pro (Windows), VMWare Fusion (Mac), or vSphere Hypervisor (free ESXi server). 

You should create a VM-only network to deploy your vulnerable VMs and perform several of the attacks using WebSploit (Kali Linux), as shown in the video above. You can configure a separate network interface in your WebSploit VM to connect to the rest of your network and subsequently the Internet. Preferably, that interface should be in NAT mode.
