Windows 10: Freeware hypervisors which do not require SLAT support

There are still many LGA775 computers in use; their Core2 Duo/Quad processors support VT-x but not SLAT/EPT which is required by several current free hypervisors. For reference, here is a list of recent versions which can run on hardware without SLAT support:

Vmware Workstation Player: 12.5.9 (not supported anymore but working without problems)
Vmware ESXi: 6.5 (end of support November 15, 2021)
Oracle Virtualbox: SLAT still is not a requirement in current version 6.1.10
Microsoft Hyper-V Server: 2008 R2 SP1 (not supported anymore but working without big problems)

Other ones can be added.

 Turn Hypervisor ON or OFF as required

I've tested Hyper-V Switch. Because it either shows the UAC prompt, or requires a scheduled task to run it, I find it a bit clumsy. I'd rather create separate boot options for Hypervisor ON or OFF.

 

Windows 10: Switched from BIOS to UEFI. Hyper-V reports that the hypervisor is not running

I partitioned my hard drive and installed Debian on second partition. In order to do this I had to switch from BIOS to UEFI after basically destorying the MBR. Everything works great. However when I choose to boot to Windows 10 my various images within Hyper-V are not starting. The error states that hypervisor is not running. Any ideas?

I tried this Hyper-V reports that the hypervisor is not running. How to start the hypervisor? but no joy. Any suggestions on why this would have stopped working?

Hi Kari...
Lots of steps on method one can be skipped by a single click,by using a portable,freeware app called: HyperVSwitch
you could add it in the tut,for the lazy people like myself.
