I am using Windows 10, can you provide a detailed step-by-step guide on how to install Genymotion?

No. Windows 10 is no longer officially supported for Genymotion Desktop, so a reliable installation guide for that OS is not available.

Genymotion Desktop supports Windows 11 on x86_64, and the Windows installer includes VirtualBox in the full installer for Windows, while Windows 10 is only mentioned as possibly working but not supported. See Get Started with Genymotion Desktop and the product page.

If Windows 11 is used, the basic installation steps are: download the Windows installer from the download page, run it, choose the install folder, optionally create shortcuts, click Install, then restart when prompted. VirtualBox is the default recommended hypervisor on Windows, and Hyper-V must be completely disabled if it is used.
