Last I checked my desktop was probably on for like 5 or 6 days, I’ll have to check it tommorow, but I’ve gotten over a month before having to reboot for updates, also I usually just put my system to sleep when I go to bed(was trying to get around slow HDD boot times, I now have NVME but haven’t broken the habit, plus nvidia drivers are being buggy and my viewport settings keep getting g reset upon reboot, plus I like to resume where I left off)
First operating system I ever used was probably Windows XP, first Linux distro was probably either Ubuntu or Puppy Linux on an old laptop (I remember trying out the Ubuntu web demo back in like 2014.)
