Windows 10: How to restore the sleep option in Windows 10 64-bit 2020

Sleep option disappeared, now I can only hibernate. How can I get back the option to sleep?

This event might be caused by a Windows update from a few days ago.

I have read other posts from Microsoft on this topic and they are useless.

64 BIT

• Switching to Windows 10 64 bit is free, you don't have to pay for it. As long as you have a qualifying Windows 7 or 8 or Windows 10 license, you are entitled to use it.
• Switching requires that you perform a new installation, that means files, applications and settings will be deleted.
• You will have to reinstall applications and native 64 bit drivers.
• Backup before migrating: How

VirtualBox in Windows 10 64-bit guest only shows 32-bit options

My Situation

I am running VirtualBox v5.2.32 on an Ubuntu 18.04 host. I have created a Windows 10 (64-bit) guest. I installed VirtualBox v6.0.10 in the Windows 10 guest (Windows 10 Pro - v1903 - 64-bit). I am trying to create an Ubuntu (64-bit) guest inside the Windows 10 guest. I only see 32-bit options inside the Windows guest. After several attempts to resolve this, I am still only seeing 32-bit options.

My Intention

The purpose for creating a VM inside a VM is to be able to ensure that VirtualBox is working so that I can test Vagrant configuration inside a Windows 10 environment. Our Vagrant config is using 64-bit base images, so I need to be able set up 64-bit guests inside this Windows 10 guest.

What I Have Already Tried

...on the Ubuntu Host

I have checked Enable VT-x/AMD-V on the System > Acceleration tab in the Ubuntu host's VirtualBox config for the Windows 10 guest machine.

...on the Windows Guest

In the Windows guest machine, I can see that the host's physical CPU details are passed through in Settings > System > About and it shows as a "64-bit operating system, x64-based processor".

This is a vanilla Windows 10 Pro installation, no additional software (i.e., no addon virus protection software).

I inspected Windows Features to ensure that the following are not checked:

• Guarded Host
  
• Hyper V
  
• Virtual Machine Platform
  
• windows Hypervisor Platform
  
• Windows Subsystem for Linux
  

...because my googleing seems to indicate that some or all of these might be an issue.

Based on a VirtualBox forum (I have a 64bit host, but can't install 64bit guests), using gpedit.msc, I set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security to Disabled. I also check that Windows Security > Device Security > Core Isolation Details is set to Off.

I have "repaired" the VirtualBox installation. I have uninstalled VirtualBox, rebooted, reinstalled, and then rebooted again.

Related Stack Exchange Questions and Other References

I looked at these related, previously asked questions and followed their suggestions as indicated in the steps above. Everything I am finding seems to be related to a Windows 64-bit host running directly on the host machine, not dealing with a Windows host which is itself a guest VM.
