attention

Docker Desktop on Windows requires hardware virtualization to be enabled. It runs Linux containers inside a lightweight virtual machine (VM) that uses either Hyper-V (or the underlying Windows Hypervisor Platform) or the Windows Subsystem for Linux 2 (WSL 2), both of which depend on your CPU's hardware virtualization capabilities (Intel VT-x or AMD-V) being enabled in the BIOS/UEFI settings.

Solution

1. Since windows home has no Hyper-v support it can't use vitualization, hence can't use docker. You can use (MAS tool)[https://massgrave.dev/] to change the version of your windows to include the feature.
2. (Enable Virtualization on Windows)[https://support.microsoft.com/en-us/windows/enable-virtualization-on-windows-c5578302-6e43-4b4b-a449-8ced115f58e1]
