You can re-enable removed components via:
Set the VM CPU type to host rather than the default kvm64 . This exposes the actual capabilities and instruction sets (like AVX) of your physical CPU to the Windows guest, vastly improving application performance. Risks, Drawbacks, and Considerations
The Qcow2 format plays a critical role in the distribution and deployment of virtualized environments. Qcow2 is a virtual disk image format used by QEMU, which allows for efficient use of disk space through features like compression and dynamic allocation. Qcow2 images can also be easily moved between different virtualization platforms that support the format, offering a degree of vendor-agnostic flexibility.
On your hypervisor host, create a target disk using the QEMU command line: qemu-img create -f qcow2 windows10_lite.qcow2 40G Use code with caution. Windows 10 Lite Qcow2
This image contains proprietary Microsoft software. You must own a valid Windows 10 license to use it beyond the 90-day evaluation period. This distribution is provided as-is for educational, testing, and virtualization convenience.
Start the VM and install the VirtIO drivers for network and SCSI functionality to ensure maximum performance. Performance Optimization Tips Even with a Lite image, you can optimize further:
Most pre-baked Lite ISOs or QCOW2 images are distributed by third-party creators. There is an inherent risk that malware, keyloggers, or backdoors could be embedded in the image. You can re-enable removed components via: Set the

(QEMU Copy-On-Write version 2) is the native disk image format for the QEMU (Quick Emulator) virtualization software. It's the standard format used in conjunction with KVM (Kernel-based Virtual Machine) on Linux hosts and is known for several key advantages over simple raw disk images.

Standard Windows 10 is packed with telemetry, background services, and "bloat" that eat up CPU and RAM. A "Lite" version (like Tiny10 or custom ISOs) offers: : Often uses less than 1GB at idle. Smaller disk footprint : Takes up ~5-10GB instead of 20GB+.
QCOW2 supports built-in cluster compression to optimize storage host space. Why Use a Windows 10 Lite QCOW2 Image? Qcow2 is a virtual disk image format used
