How To Track Your Computer’s Boot Time

Computers slow down over time. There are a lot of reasons why this happens. A PC will boot the fastest after a clean install. But after installing a lot of different applications and falling behind on your general computer maintenance, your computer’s boot time will gradually increase.

You can use the Windows Event Viewer to track your boot time speeds to see how much your computer’s boot time has increased over a several month duration.

How To Use The Event Viewer To Find Your Computer’s Boot Time

To begin, you’ll first need to launch the Event Viewer. There are several ways to do this. The easiest way it to go to the Start button and then type Event Viewer into the search box. Or you can find the Event Viewer in the Administrative Tools section of the Control Panel.

After you launch the Event Viewer, click the Applications and Services Logs link in the left-hand pane.

Next, click the Microsoft folder, and then the Windows folder. You will then see a folder for Diagnostics Performance. And within that a folder called Operational. So the click through path is Microsoft>Windows>Diagnostics Performance>Operational.

After you double-click on Operational, you will see an option to Filter Current Log in the right pane. Click on that to filter the results.

Under the Event level, we want to tick the Warning box. In the Includes/Excludes Event IDs field, we want to type 100. Windows assigns each event an ID. This particular ID is associated with Windows starting up.

You can now sort these start-up events by date and time. Click on the Date and Time tab at the top so the dates are descending. Double click the most recent event to see your computer’s boot time.

The time is displayed in milliseconds. Divide that number by 1000 to get your most recent computer boot time. In this case, it took this computer 37 seconds to boot.

To see how much your boot time has increased over the months, scroll down the list and open a different date. In this case, this particular computer booted nearly twice as fast six months earlier at 19 seconds.

Now that we have a way to track our computer’s boot time, we can take measures to speed it up. To reduce your computer’s boot time, consider defragging your hard drive, uninstalling unnecessary programs, and reduce the amount of programs in your start-up folder.

Try this on your own computer and let us know your computer’s boot time over a six month duration.
