See How Long Your PC Has Been Running
UpTime v2.00 is a lightweight, completely free utility that displays how long your Windows system has been running since its last restart. Perfect for IT professionals, system administrators, or anyone curious about their system's runtime, UpTime provides that information in a clean, borderless window that stays out of your way.
Windows uptime is the total time your computer has been running since it was last restarted or powered on. Whether you are tracking server reliability, monitoring reboot frequency, or just want to know how long your PC has been on, UpTime gives you a clear, always-visible answer. v2.00 is a complete rewrite with updated Windows uptime calculation methods and a modern interface.
