How to change conda base directory (where .condarc resides)

Question

In Windows 10, anaconda creates .conda and .condarc in in %userprofile%. I want to move this so that I can have a Anaconda instalation under Windows and another under WSL (Ubuntu), each with its environments and settings. How does one move or set the base directory in conda?

(base) C:\Users\user>conda info

     active environment : base
    active env location : C:\Users\user\AppData\Local\Continuum\anaconda3
            shell level : 1
       user config file : C:\Users\user\.condarc
 populated config files : C:\Users\user\.condarc
          conda version : 4.6.11
    conda-build version : 3.17.8
         python version : 3.7.3.final.0
       base environment : C:\Users\user\AppData\Local\Continuum\anaconda3  (writable)

It turns out two conda instalations, one under Windows Subsystem for Linux, and another under Windows, will not clash:

Under WSL bash shell:

(base) $ conda info| grep "user config file"
       user config file : /home/tams00/.condarc
(base) $

On the anaconda powershell:

(base) PS>conda info | Select-String -Pattern "user config file"

       user config file : C:\Users\tams00\.condarc

(base) PS>

Although this was not immediately obvious to me /home/user/ is different from C:\Users\user.
