Whether you are a DevOps engineer testing cross-platform scripts, a student learning Windows internals, or a Linux user needing occasional access to Microsoft Office, the Windows 10.qcow2 combination is unrivaled.

To help you get this VM running perfectly, please let me know:

Because QCOW2 dynamically grows, deleting files inside Windows 10 does not automatically shrink the .qcow2 file on your host machine. Over time, the image suffers from storage bloat. How to Shrink a Bloated Windows 10 QCOW2 File Windows 10.qcow2

The resulting windows10_compressed.qcow2 file is now fully optimized and ready to serve as a baseline template across your cluster. Deploying Your .qcow2 File on Proxmox VE

Because Microsoft does not officially distribute pre-built Windows 10 images in the QCOW2 format, you must build one yourself using a Windows 10 ISO and Red Hat’s . Without VirtIO drivers, KVM/QEMU cannot recognize the virtual storage controller or network adapter during installation. Prerequisites

Once you have a Windows 10.qcow2 disk image, you can use it on various virtualization platforms.

Run the following QEMU command to boot the VM, mounting both the Windows 10 installation media and the VirtIO driver disc:

qemu-img convert -O qcow2 -c Windows10.qcow2 Windows10_optimized.qcow2 Use code with caution. How to Shrink a Bloated Windows 10 QCOW2

To build a high-performance Windows 10 environment, you must bypass the standard IDE/SATA storage bottlenecks by utilizing specialized drivers. Download these official components first:

For specific lab environments, pre-built images are sometimes available, though they often require your own license key: Building a Windows Server QCOW2 Image - Jamie Phillips

Download the latest Windows 10 Media Creation Tool or ISO directly from the Microsoft evaluation portal or official website.

This is the most common method. You will create a blank QCOW2 disk image and then install Windows 10 onto it using an installation ISO. This process is the same regardless of which virtualization software you plan to use later.

Over time, writing and deleting data inside the Windows VM causes the QCOW2 file on the host to expand continuously. Even after files are deleted inside Windows, the host file system keeps the storage blocks allocated. You can drastically shrink the footprint of your template image using a two-step optimization process. Inside the Windows VM: Zero Out Free Space
