Set default os in WSL

[elahia]

Hi guys,

by WSL_distribution_switcher i could install ubuntu14.04

so that by runnng:
python.exe switch.py
The following distributions are currently installed: -```

ubuntu:14.04*       
ubuntu:xenial  

Now i want to set ubuntu14.04 as the default one, but i got this error:

C:\...s\WSL-Distribution-Switcher-master\WSL-Distribution-Switcher-master>wslconfig /setdefault Ubuntu14.04       
 There is no distribution with the supplied name.                                                                                                                                                                                                

but if i try for following command :
`C:\Users\elahe\Downloads\WSL-Distribution-Switcher-master\WSL-Distribution-Switcher-master>python.exe switch.py ubuntu:14.04

[*] Probing the Linux subsystem...
[!] The ubuntu:14.04 rootfs is the current installation.`

but in WSL i got:
lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.4 LTS Release: 16.04 Codename: xenial

so why i dont have ubuntu 14.04 as the defualt one?
