Problems installing Hyper-V on Windows 8.1

I was trying to set up a Mobile Development Environment in my system with Windows 8.1. I did not that know it was not a PRO version and I never wanted that PRO version until this point.

Windows emulator requires Hyper-V as a pre-requisite and Hyper-V cannot be installed in Windows 8.1 (it requires Windows 8.1 pro or higher)

Now, the only option that I see is, format the PC and fresh install Windows 8.1 Pro or higher but this is not a viable option to me because this is a working machine and it will waste my a day or two in configuring the environment.

Isn't there a standalone installer for Hyper-V where I should not format/reinstall my OS ?

Any help/suggestions will be highly appreciated.

Thanks,

Kushal.
