Microsoft will end support for Windows 10 on October 14, 2025. Users can run Windows 10 in a virtual machine (VM) to continue using it safely. The tool Disk2Vhd can convert a physical Windows 10 installation into a virtual hard drive (VHD or VHDX) for use in virtualization software like VirtualBox or Hyper-V. To use Disk2Vhd, download and extract it, launch the appropriate executable, select partitions for conversion, and choose between VHD and VHDX formats based on the virtualization software. After conversion, transfer the VHD file to the target computer and set up a new VM, integrating the backup file instead of creating a new virtual hard drive. Users can also reinstall Windows 10 in a VM using an installation medium and the Media Creation Tool to download the ISO file. When creating a VM, allocate at least 4GB of virtual memory and install necessary programs and guest extensions afterward. Creating a backup point after installation is recommended for stability.
