This video show how to install Install Ubuntu 17.04 on Windows 10 with Oracle VirtualBox 5.1. Basically, the steps is very straightforward.
But...after setup, I cannot google in the browser. And it was found some sites can be reached, some sites cannot. Even cannot run apt-get update. After some searching, I found it's related to DNSSEC in /etc/systemd/resolved.conf.
To fix it, edit the file /etc/systemd/resolved.conf:
$ sudo nano /etc/systemd/resolved.conf
uncomment #DNSSEC=allow-downgrade and replace allow-downgrade with off .
Install Guest Addition:
The Guest Additions are designed to be installed inside a virtual machine after the guest operating system has been installed. They consist of device drivers and system applications that optimize the guest operating system for better performance and usability. (https://www.virtualbox.org/manual/ch04.html)
It's strongly recommended to install Guest Addition. In case of Ubuntu 17.04, simple click Devices on VirtualBox menu bar, and click Insert Guest Addition CD image...
Share folder between host Windows 10 and guest Ubuntu 17.04:
Starting with version 4.0, VirtualBox can mount shared folders automatically, at your option (link). This video show how to set auto-mount share folder in host Windows 10, and also add user to vboxsf group in guest Ubuntu to access the share folder. (Guest Addition is need)

Starting with version 4.0, VirtualBox can mount shared folders automatically. In case on Linux guests, auto-mounted shared folders are mounted into the /media directory, along with the prefix sf_. For example, the shared folder myfiles would be mounted to /media/sf_myfiles on Linux and /mnt/sf_myfiles on Solaris. Access to auto-mounted shared folders is only granted to the user group vboxsf, which is created by the VirtualBox Guest Additions installer. Hence guest users have to be member of that group to have read/write access or to have read-only access in case the folder is not mapped writable.
The below video show how to create share folder between host Windows (D:\vbShare) and guest Ubuntu Linux (/media/sf_vbShare), and add current user to the vboxsf group with the command:
$ sudo usermod -a -G vboxsf eric
where:
vboxsf is the user group own the shared folder
eric is the the current user
This post show how to connect Windows 10 to HC-06 Bluetooth Module.
Actually it's a loopback connection:
PuTTY Serial connect to Bluetooth Outgoing port -> (Bluetooth) -> HC-06 -> FT232RL -> (USB) -> Arduino IDE Serial Monitot.
This video show how to pair HC-06 on Windows 10, and try the loopback test.
In VirtualBox, with Addition CD Image installed (refer to the post "Install Ubuntu 15.10 on Windows 10/VirtualBox"), you can enable the feature of Shared Clipboard and Drop'n'Dop to copy/cut text between host and guest..
In my case:
Host on Windows 10.
Guest running Ubuntu 15.10.
I can use both clipboard and Drag'n'Dop from host Windows 10 to guest Ubuntu, clipboard from guest Ubuntu to host Windows. BUT NOT Drag'n'Drop from guest Ubuntu to host Windows, it make the guest Ubuntu hang-up!
Ubuntu GNOME is an official flavor of Ubuntu, featuring the GNOME desktop environment. This video show how to install Ubuntu GNOME 15.10 on Windows 10 with VirtualBox. (Basically, it's same as Install Ubuntu 15.10 on Windows 10/VirtualBox).
Download Ubuntu GNOME 15.10 and install on VirtualBox.
Insert Guest Additions CD Image to improve display resolution.
Create shared folder between guest Ubuntu GNOME 15.10 and host Windows 10.
To share folder, setup Shared Folder in VirtualBox Setting of the guest, assign a machine folder in host. Then run the command in guest Ubuntu Linux
$ sudo mount -t vboxsf vbShare mntShare
where: vbShare is the shared folder in host, and assigned as Shared Folder in VirtualBox Setting of the guest. mntShare is the folder in guest Ubuntu Linux.
With Addition CD Image installed, we can improve screen resolution and share folder between guest Linux and host running Windows.
This video show how to, and the screen reesolution improved.
To share folder, setup Shared Folder in VirtualBox Setting of the guest, assign a machine folder in host. Then run the command in guest Ubuntu Linux
$ sudo mount -t vboxsf vbShare mntShare
where: vbShare is the shared folder in host, and assigned as Shared Folder in VirtualBox Setting of the guest. mntShare is the folder in guest Ubuntu Linux.
Recently, the Store of my Windows 10 always show some app is starting update, but no any progress, and I cannot install any apps.

finished. Now I can update and install app.
I use HWiNFO recently, found that my Windows 10 computer loading raise sometimes, without any reason. Then I check which process is running using Task Manager. The highest work load task is "svchost.exe Service Host: Local System"!
In the Windows NT family of operating systems, svchost.exe (Service Host, or SvcHost) is a system process that hosts multiple Windows services. Svchost is essential in the implementation of so-called shared service processes, where a number of services can share a process in order to reduce resource consumption. Grouping multiple services into a single process conserves computing resources, and this consideration was of particular concern to NT designers because creating Windows processes takes more time and consumes more memory than in other operating systems, e.g. in the Unix family. However, if one of the services causes an unhandled exception, the entire process may crash. In addition, identifying component services can be more difficult for end users. Problems with various hosted services, particularly with Windows Update, get reported by users (and headlined by the press) as involving svchost.
