• Intel Virtualization Technology (VT-x): Default: Disabled.
  Why enable? Required for VMware, VirtualBox, and WSL 2. Enabling this allows your CPU to run multiple operating systems simultaneously without lag.
• VT-d (Directed I/O): Default: Disabled.
  Why enable? Allows VMs to directly access hardware (GPUs, NVMe drives). If you run a home server, enable this.
• Hyper-Threading: Default: Enabled.
  Only disable if you are debugging software that crashes with logical cores.
• Active Processor Cores: Allows you to disable cores (useful for overclocking stability or saving battery on dual-core chips).
