❓ What If Nothing Works? (BIOS/VT-x Check)

In rare cases (less than 2% of Windows computers), virtualization might be disabled in your computer’s BIOS. This is most common on:

  • Corporate/managed laptops with IT restrictions
  • Some budget Windows tablets

How to check:

1. Open Task Manager (Ctrl + Shift + Esc)

2. Go to Performance tab → CPU

3. Look for “Virtualization: Enabled” at the bottom

If it says “Disabled,” you’ll need to enable it in BIOS. Microsoft’s official guide for enabling virtualization walks you through this [5].
