Hyper-V

Follow the steps of the following link, you will find some options on activating Hyper-V

Hyper-V

Hi,

Hyper-V has a dependency on your System supporting and having enabled Hardware support for Virtualisation. Because of how allocates system resources to a VM directly rather than the simulated approach of a normal VM program. This is typically listed as either
"Virtualization" or "Intel Virtualization Technology" please check this is enabled in your BIOS.

Without it, even if it has been enabled through Windows Hyper-V won't properly activate as it isn't supported.

 

Can't Enable Hyper-V in Windows 10 Professional

Hi,



Thank you for writing to Microsoft Community Forums.



I appreciate your effort on this. As per my research the error code 0x800f0831 is generated when .Net Framework 3.5 is not enabled on the computer. I suggest you to try enabling .Net Framework 3.5 on the computer. Follow the steps mentioned below:

1. Press Windows key + R, to open
   Run dialog box.
   
2. Type appwiz.cpl and click on
   OK.
   
3. Click on Turn Windows features on or off.
   
4. Now, select the check box for .Net Framework 3.5 and click on
   OK.
   
5. Restart the computer.
   

You can also check if Virtualization feature is enabled in BIOS or not, if it is not enabled, I suggest you to enable it.
