Ever noticed that your Windows 11 PC has been “on” for days, even though you shut it down last night? If you check your system’s uptime in Task Manager and see it still counting up from dozens of hours, you’re not alone.
That’s because of a feature called Fast Startup, which keeps your PC in a hybrid state—something between a shutdown and hibernation. While it’s helpful for boot speed, it doesn’t actually reset your PC’s uptime counter.
In this detailed guide, we’ll walk you through how to properly reset your PC’s uptime by disabling Fast Startup and performing a full shutdown.
Let’s get started and give your system a truly fresh start!
💡 What Is Uptime, and Why Should You Care?
Before diving into the steps, let’s understand what “uptime” really means.
Uptime is the amount of time your system has been continuously running without a full shutdown. If your PC shows 20+ hours of uptime despite shutting it down last night, that’s Fast Startup at play.
Why reset uptime?
- 🛠 For troubleshooting performance or memory issues
- 🧹 To fully clear RAM and system processes
- 🔌 For accurate system monitoring or IT audits
Now let’s reset that counter properly.
✅ Step-by-Step Guide to Reset Uptime in Windows 11
We’ll break it down into easy-to-follow steps. If you’re someone who likes to keep things tidy and efficient, you’ll love how simple this is.
🧭 Step 1: Check Current Uptime
Let’s first confirm how long your PC has been running.
- Press Ctrl + Shift + Esc to open Task Manager
- Click the Performance tab
- Look at Uptime under the CPU section
This shows how long your PC has been on (without a full shutdown). If it says 20+ hours, your system has been in a semi-hibernated state.
Now, let’s move forward and change that.
⚙️ Step 2: Disable Fast Startup from Control Panel
This is the key step! Fast Startup prevents a complete shutdown. Disabling it allows Windows to shut down completely, resetting the uptime.
Here’s how to do it:
- Press Windows + S and search for Control Panel
- Open Control Panel and go to Power Options
- On the left panel, click Choose what the power buttons do
- Now click Change settings that are currently unavailable
- Under Shutdown settings, uncheck the option Turn on fast startup (recommended)
- Click Save changes
🎉 Great job so far! You’ve just turned off the setting that keeps your PC half-awake.
⏹️ Step 3: Fully Shut Down Your PC
Now it’s time to shut down your computer the proper way.
- Click the Start menu
- Click the Power icon
- Select Shut down
Let your system power off completely. Wait a few seconds before restarting it.
🔁 Step 4: Recheck Uptime After Boot
Once your PC is back on, let’s see if the counter reset worked.
- Again, open Task Manager (Ctrl + Shift + Esc)
- Go to the Performance tab
- Check the Uptime
It should now show just a few minutes or seconds—starting from zero. This confirms that the system performed a full shutdown, and Fast Startup is no longer interfering.
