Running Unix services at startup on Windows with WSL

Open a WSL terminal
Run sudo visudo
Add a line allowing the service to be started without a password. Ex:
```
%sudo ALL=NOPASSWD: /etc/init.d/<my-service> start
```
Open the Windows Run prompt (Window Key + R) and type "shell:startup" to open the startup folder.
If you have "Bash on Ubuntu on Windows" (the old version of WSL) Create a shortcut in the startup folder with location
```
C:\Windows\System32\wsl.exe sudo /etc/init.d/<my-service> start
```
For newer Windows app store versions of WSL such as "Ubuntu 20.04 LTS"
- Open a WSL terminal
- Open task manager
  - ctrl + alt + del
  - Select "Task Manager"
  - Select "More details"
- Select the "Ubuntu 20.04 LTS" process tree
- Right click on one of the "Ubuntu 20.04 LTS" processes
- Select "Open file location"
- Copy the path to the ubuntu exe
- Create a shortcut in the startup folder with location set to something like
```
"C:\Program Files\WindowsApps\CanonicalGroupLimited.Ubuntu20.04onWindows_2004.2020.812.0_x64__79rhkp1fndgsc\ubuntu2004.exe" run sudo /etc/init.d/<my-service> start
```
Restart your computer and open task manager to verify the service is being started
Whenever WSL is updated, the paths to the executables will change and you will need to update the shortcuts.

Example: Running cron jobs on Windows with WSL

Follow the above directions substituting "cron" for "my-service." Then add cron jobs by running crontab -e as usual.

If you try running "screen" in WSL you get the following error by default:

$ screen -ls
Cannot make directory '/var/run/screen': Permission denied
$

To fix the error follow the above directions to run "sudo /etc/init.d/screen-cleanup start" at system startup.

You may have to change the file extension after downloading to ".lnk" because Chrome automatically renames the files to prevent "abuse".
