@Hansana Adhikari If you unchecked Hyper-V in Windows Features and restarted, then Hyper-V isn't even installed anymore, so it wouldn't be running. On systems where I need to have Hyper-V installed but occasionally need to disable it, I create a secondary boot menu option.
Open Command Prompt as administrator and enter this to create a new boot entry called "Windows 10 w/o Hyper-V" as a duplicate of your current boot entry:
Then find the ID of the new entry that was just created. It will be surrounded in braces/curly brackets. Highlight that and copy it to your clipboard, then enter this command and provide the ID where it's needed:
bcdedit /set {YourNewID} hypervisorlaunchtype Off
Finally, go into msconfig/System Configuration, go to the Boot tab, and set the boot menu timeout to some non-zero value. Now when you restart you'll see a boot menu where you'll have an option to boot with Hyper-V disabled. If you don't make any selection within the timeout value, then your system will boot from your original boot menu entry as its default. If you ever want to remove that additional boot menu entry, you can do that in msconfig/System Configuration.
@Hansana Adhikari It might just be permanently enabled. Are you getting some error that suggests it's not enabled? If so, do you have any other hypervisors installed, like Windows Hyper-V? That would prevent you from starting other virtualization engines.
@Hansana Adhikari Ok, well if you were able to have Hyper-V installed and running in the first place, then virtualization is already enabled at a hardware level, because Hyper-V these days requires virtualization and SLAT capabilities to be enabled. When you say you've disabled Hyper-V, what does that mean? To completely disable Hyper-V, you need to actually boot Windows with the hypervisorlaunchtype option set to off. This is typically accomplished by duplicating your existing BCD entry and then making that change on the duplicate copy so that you can choose whether to boot Windows with Hyper-V enabled or not at any given time. Or you could just uninstall Hyper-V. But simply stopping Hyper-V VMs and Hyper-V services in Windows will not stop the actual hypervisor from loading at boot.

I have disabled hyper-v, the only place where I see that virtualization is enabled is in task manager.

You got the case actually, I need to disable the hypervisor that is running on my PC even though I disabled Hyper-V using Windows Features.
Let me know if you have any method of disabling the hypervisor.
