Ensure your drivers are compatible. HVCI blocks drivers that are not properly signed or contain suspicious behavior.
Hardware virtualization is unequivocally better on Windows 11 than on many prior mainstream consumer Windows releases, for three practical reasons: tighter platform integration, improved firmware/driver expectations, and clearer security-virtualization synergy. Those gains produce a noticeably smoother experience for both everyday users running VMs and for developers and IT pros who rely on nested virtualization, containers, or sandboxed tooling.
Windows 11 represents a paradigm shift in operating system architecture, moving hardware virtualization from an optional "power user" feature to a core requirement for security and compatibility. With the introduction of Virtualization-Based Security (VBS), Hyper-V Recompose, and Windows Subsystem for Android (WSA), the hypervisor is now active by default on compliant hardware.
The single most important reason virtualization makes Windows 11 better is . hardware virtualization windows 11 better
Need to open a suspicious email attachment or run a sketchy executable? Windows Sandbox creates a temporary, pristine desktop environment that is completely isolated from your host PC. The moment you close Sandbox, the entire environment is wiped out. Microsoft Defender Application Guard
Newer CPUs (like Intel 12th Gen or AMD Ryzen 5000 and above) handle this overhead much better, typically seeing only a 3-5% drop . Older supported CPUs experience more significant stutters and lag.
Enabling virtualization is a two-step process: first in your BIOS/UEFI firmware, then in Windows settings. How To Enable Virtualization In Windows 11 - 2026 Ensure your drivers are compatible
Restart your PC and enter the (usually F2, F10, or Del). Find Intel VT-x or AMD-V . Set it to Enabled . Save and Exit. If you'd like to dive deeper, let me know:

But those same protections come at a cost. Recent tests show that VBS can impact gaming performance by as much as 5–10%, with particularly noticeable effects in CPU‑intensive titles like Microsoft Flight Simulator. In some cases, particularly on older CPUs like first‑generation Ryzens or 10th‑generation Intels, the performance hit can reach up to 28%. Those gains produce a noticeably smoother experience for
Your physical CPU (Intel or AMD) features dedicated, built-in instructions designed to handle virtual workloads natively.
This capability has become a lifeline for users with older but still performant hardware. Hypervisors like Hyper‑V, VMware, and VirtualBox now include virtual Secure Boot and TPM support, allowing Windows 11 to install without problems and never throwing unsupported hardware warnings.
If it says disabled, you must reboot your PC and enter your firmware settings (usually by tapping F2 , F10 , or Del during startup).
If you are running a VM inside Windows 11 (e.g., a Windows 10 VM inside Hyper-V) and want to run Docker inside that VM, you need Nested Virtualization.
