Issue: How to Disable Hyper-V in Windows 10?

Hello all. Do you have any ideas why Windows does not allow me to uninstall Hyper-V? When I try to do so, I get an error saying: “The changes couldn't be completed. Please reboot your computer and try again. Error Code: 0x800F0831.” I’ve tried many things, including bcedit option, powershell scripts, DISM, and some other things, but none of them worked. Have you any ideas?

Solved Answer

Hyper-V is not a tool for inexperienced PC users. It’s a utility, which replaces Microsoft Virtual PC and allows running multiple operating systems on a single device. Hyper-V simplifies the lives of software developers, professional IT workers or tech-savvy people who opt for working or experimenting with multiple OS, including various Linux releases, FreeBSD, and Windows. When using the tool, there’s no need for physical hardware injected into machines. Hyper-V turns different OS into virtual machines (“guest”), which run in tandem on a single computer (“host”).

Disable Hyper-V

While the tool is useful for many PC enthusiasts and experts, many of them find it lacking for some features, for example, live migration of virtual machines from one host to another, Hyper-V Replica, Virtual Fiber Channel, virtualizing GPUs using RemoteFX, and so on. Due to this or other reasons, they decide to switch to other virtualization products. The problem is that sometimes Hyper-V removal fails and returns errors like “The changes couldn't be completed. Please reboot your computer and try again. Error Code: 0x800F0831.” There were some instances when .Net Framework 3.5 were missing or damaged, which is why the removal process could not be completed. If you are experiencing this same problem, the following methods may help you:

  • Press Windows key + X and select Apps and Features.
  • Scroll down to the bottom and click Programs and Features link.
  • Then click the Turn Windows features on or off link on the left pane.
Step 1
  • Locate Hyper-V option and unmark it.
  • Click OK to save the changes and reboot.

Disable Hyper-V via Command Prompt and PowerShell environments

  • Right-click on Windows key and select Command Prompt (Admin).
  • Copy and paste the Dism /Online /Cleanup-Image /RestoreHealth. Press Enter.
Step 3

  • Now type the sfc /scannow and press Enter again.
  • Close Command Prompt and open Windows PowerShell (with administrative privileges).
  • Type PowerShell in Windows search, right-click it, and select Run as Administrator.
