virtual machine manager for eval

Oracle VirtualBox is quite good product, that would not expire, and you can also try it. Here is its download

There is no non-VHD download for *just* SCVMM available from microsoft. However, you can download an EXE file that has all of the System Center components from the eval center: https://www.microsoft.com/en-us/evalcenter/evaluate-system-center-2012-r2

Just as a note, though, as of Windows 2012, you can mount VHDs directly in the OS by right clicking them and selecting Mount, so you don't have to attach it to a VM, if that's what you're looking for.

If you are using Windows 10 Pro, it is a feature included with the OS. Just add the Feature in the control Panel, Programs and Features, then select "Turn Windows features on or off". Besides that, if your PC's hardware supports it, you can even enable Hyper-V itself if you want to run some local VM's (is the same with Windows 8.1, but by now no one should be running that OS anymore).

Are you talking about virtual machine manager? I'm talking about system center virtual machine manager. Many thanks.

Correction.  Are you talking about hyperv manager?

Thanks all but this is what I was looking for.
