Microsoft has updated its Microsoft Edge developer site, adding downloadable Windows 10 virtual machines for VirtualBox, VMware and Hyper-V.

Although these are aimed at developers, they’re a quick and easy way for anyone to try out Windows 10.

We downloaded a VirtualBox VM, imported it, clicked Start and it booted directly to the desktop, no installation required.

No Windows installation required, just import the VirtualBox OVA file and it’s ready for use immediately

This got us a copy of Windows Enterprise RTM, build 10240. It expires after 90 days, but if you revert to a snapshot or just re-import the VM then you can start the clock again.

That’s the theory, at least – we noticed our VM displayed its license as “expired” on first launch. But it still worked just fine, so we downloaded the latest Windows updates, restarted the VM and this time it correctly displayed “Windows License valid for 90 days”.

Windows 10 virtual machines are now available for VirtualBox, VMware and Hyper-V on Windows, Linux and Mac.
