Replace your-host-name with your host name.
Edit /etc/hosts, replacing every occurrence of the old host name with your new host name.

Change the default login user for a distro

Use a distro command like

Fix the time issue after Windows sleep

The issue is that when a WSL distro is open and Windows starts sleep, then the date time on the distro may be incorrect after the sleep. The fix is to to enable the systemd-timesyncd service on the distro.

Ensure systemd is enabled as said by Enable systemd
Install systemd-timesyncd if not, by
```
sudo apt install systemd-timesyncd
```

Edit its config by

sudo systemctl edit systemd-timesyncd

Ensure the config has

[Unit]
ConditionVirtualization=

Start or restart it by

sudo systemctl start systemd-timesyncd

sudo systemctl restart systemd-timesyncd
