How to Disable Hyper-V in Windows 10?

Issue: 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 bcdedit 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.[1] 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”). 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.” Users[2] also search for ways to make the program more user-friendly since it is difficult to disable/ enable the app when needed.

Also, like with other programs, there are possible issues with compatibility when some third-party applications are not working along with this app, so people need to disable Hyper-V when trying to launch any other piece of software. Such behavior seems to be common because various virtualization applications depend on the particular hardware extensions that are available on processors.

Only one software component can use this hardware virtualization extension at the time and those pieces cannot be shared. The problem causes crashes and keeps the user from using Hyper-V or different software until one of them is completely disabled.

Disable Hyper-VThere were some instances when .Net Framework 3.5 were missing or damaged, which is why the removal process could not be completed. It can be related to PUPs[3] and other unwanted third-party apps that trigger changes. You might repair some system files and damaged pieces with tools like FortectMac Washing Machine X9 quickly.
