Restore Desktop

I've lost my Raspberry Pi desktop taskbar and icons!

If you've accidentally removed your Raspberry Pi OS taskbar and icons, there are a couple of ways you can get these back. The following is valid for all models of Raspberry Pi, including the Pi 400:
Terminal commands - open a new terminal window (via SSH or similar if you have no terminal icon) and enter the following command:
rm -r /home/pi/.config/lxpanel

Which version of RPI OS do I have installed?

pi@piZero2:~ $ cat /etc/os-release
