I have 11 years old pc ( Toshiba L505-110). I was using win10 but it was horrible for my pc. Then, I switched to Zorin Os. It feels better, more usable but I still find this little bit slow. I have regret about not downloading Zorin OS lite. I cannot set thing up again. Is there a way to switch Zorin Os Lite without losing data ? Or switching to xfce environment via terminal can help about speed?
