How to remove/reset Windows Subsystem for Linux on Windows Insider Build 14316

Question

I installed the Windows Subsystem for Linux on Windows 10 Insider Preview build 14316. Now I would like to remove it or, better, revert to its factory defaults i.e. as it was when just installed.

I tried, to remove it from the "Turn Windows features on or off" windows, with no luck. I tried, to mark it as "off" in the above windows and delete its files manually located in %USERPROFILE%/AppData/Local/lxss, with no luck.

Has anyone succeeded in removing/resetting the Ubuntu user-mode environment?

The following answer only applies to WSL on Windows 10 1703 and 1607. WSL on Windows 10 1709+ can be installed from within the Windows Store UWP application.

If you want to remove and reset the Linux subsystem, open a command prompt with elevated permissions and enter the following commands:

lxrun /uninstall /full 

lxrun /install

I was having problems with installing BASH, it would always hang at "Expanding Filesystem...". When I ran

lxrun /uninstall /full

it would error out.

To fix this, I did a reboot. Ran this again as soon as the computer came back up. This worked. Then I found there is an issue related to installing the BASH prompt.

And someone brought up about pagefiles. I have four drives and three of them had pagefiles. I set the pagefile to one drive and set it to be automatically managed. Rebooted the computer. Then I was able to install the BASH prompt for Windows, but instead of using lxrun /install I used

bash.exe -c "ps auxf"
