   * //Enough// space on ''C:\''. Microsoft instructions say //The Windows Subsystem for Linux only runs on your system drive (usually this is your C: drive)//
     * Exporting a //simple// Ubuntu configuration (after doing everything from //Base installation// to //Advanced configuration// below) with the [[other:win10wsl#creating_a_backup_of_the_linux_running_in_wsl|wsl --export]] command generated a 2.7 Gb tar file (uncompressed), so it's probably good to **start with at least 3 Gb of free space on ''C:\''** (and you always need to keep enough free space on ''C:\'' for regular Windows operation)
