<code bash sudoers>
%sudo ALL=NOPASSWD: /etc/init.d/ssh start
</code>

Put to the ''shell:Startup'' folder bat file with the content:
<code bat ssh.bat>
powershell.exe "& 'C:\Windows\System32\bash.exe' -c 'sudo /etc/init.d/ssh start'"
</code>

==== Start WSL - bez přihlášení - no login ====

Start WSL on boot without login\\

I found that you have to keep a WSL session (started by wsl.exe, some process that's invoked by SessionLeader in pstree) running, otherwise WSL simply quits after some time.

My solution (WSL2 on Windows 11):

(optional) enable systemd in /etc/wsl.conf (for starting various services automatically, such as sshd, cron, rsyslogd, etc.)

get nircmd fom https://www.nirsoft.net/utils/nircmd.html

write a batch which has: @start /b \path\to\nircmd.exe execmd wsl ~

Use Task Scheduler to start the batch (when system starts)

===== Problém se spuštěním nainstalované distribuce =====

Po spuštění nového terminálu příksazem ''bash'' se objeví hláška ''"No installed distributions when there are indeed distros installed"''

Pomohlo zastavit a znovu spustit službu pod kterou běží WSL.

<code>
net stop LxssManager
net start LxssManager
</code>


===== Ověření nainstalované distribuce =====

<code>
wslconfig /list /all

Windows Subsystem for Linux Distributions:
Debian (Default)

===== Windows 11 =====

Kromě funkce WSL je potřeba zapnout funkci **Platforma virtuálního počítače**
