What does uptime mean

Windows 10: correctly interpret operating time in Windows Task Manager

01 Determine the runtime since the last Windows start or system uptime

Only the name that Microsoft has chosen is misleading. The manufacturer understands operating time as the runtime since the last Windows start. However, this does not mean that the computer was switched on, but rather the last time the user restarted Windows. The operating time also continues if one of the energy-saving modes (save energy or Hibernation) is activated.

02 Force restart

You can restart the system via the start menu and the command Start anew force. But it is also due once a month on Patch Day. If, on the other hand, you - as in the majority of cases - close Windows 10 via the power switch on the PC or via the shutdown command from the start menu, the quick start mechanism starts. This is active by default and means that the operating system only goes into sleep mode, which saves time when you wake up.

  1. Windows 10 uptime
    The information on the operating time can be found in the Task Manager. After you have started it, switch to the "Performance" tab.
  2. Windows 10 uptime
    The value under "Operating time" is usually quite high, although you regularly switch off the computer at the end of the working day.
  3. Windows 10 uptime
    If you switch off the PC using "Save energy" or "Shut down", the counter for the operating time continues to run. The situation is different with a restart, as also occurs with the monthly patch day.
  4. Windows 10 uptime
    The “Restart” command from the start menu has reset the operating time.
  5. Windows 10 uptime
    The quick start mechanism, which only puts Windows into a kind of sleep mode when it shuts down, can be deactivated. To do this, select “Energy Options” from the start menu.
  6. Windows 10 uptime
    In the following dialog click on the link “Additional energy settings”.
  7. Windows 10 uptime
    Windows will then lead you to the familiar Control Panel. Here you select “Choose what to do when you press power buttons”.
  8. Windows 10 uptime
    You cannot deactivate any of the checkboxes below yet. So first click on "Some settings are currently unavailable".
  9. Windows 10 uptime
    Then remove the tick in front of the option "Activate quick start (recommended)" and finally apply your changes. Windows now also resets the operating time counter when you shut down the computer, for example by pressing the power button.

03 Switch off the quick start mechanism

The quick start mechanism can be switched off so that Windows also resets the operating time when it shuts down. The option is hidden in the old control panel. You can get there, for example, if you are in the start menu Energy options call and click the link Additional energy settings click. Now select on the left side of the dialog Choose what to do when you press power buttons.

The shutdown settings are grayed out in the next window. Hence, you need to click the link above first Some settings are currently unavailable click. Then remove the tick in front Enable quick start (recommended) and save your changes. (hal)
