Easily see how many days it's been since Windows was powered up or rebooted

  • I use Windows 8.1 like many folks, for weeks at a time, without rebooting or shutting down. I suspend to save power when done for the day, and resume the next time I'm working. I don't bother to reboot until I really need to, such as after Patch Tuesday, or when some other issue crops up that makes it necessary.

    When troubleshooting memory leak issues that typically crop up when some apps (and services) are left running for days, I find it helpful to know exactly how much time has gone by since I last powered up my system, or rebooted Windows.

    The method is super easy, demonstrated with the mere 745KB animated GIF displayed below, using the newer-fangled Task Manager that's included with:

    • Windows 8
    • Windows 8.1
    • Windows 10
    • Windows Server 2012
    • Windows Server 2012 R2 (including Essentials)
    • Windows Server 10

    Let's have a little fun with this. What's the longest "Up time" story that anybody out there would like to share?

    Just drop a comment below, along with your screenshot, no registration required.
