For a persistent (non-expiring) Windows 11 image, the community often turns to verified repositories.

Add a vTPM (Virtual Trusted Platform Module) device configured for TPM 2.0. Method 2: Registry Bypass During Setup

To install Windows 11 as a high-performance virtual machine using the format, you generally should not look for a pre-made QCOW2 download, as official sources only provide ISO images. Instead, the "best" install involves creating your own QCOW2 disk and loading VirtIO drivers during the setup process for near-native speed . 1. Download the Necessary Components

: Essential for high-performance networking and storage in KVM/QEMU. Download the latest virtio-win.iso from the official Fedora repository . 2. Create the .qcow2 Disk Image

Install swtpm and add:
