Every Windows user has faced the frustration of a slow, lagging system at one point or another. Whether it’s a delay in opening applications or a drop in overall system performance, these issues often stem from inefficient disk management. Thankfully, Microsoft provides two powerful utilities—Disk Cleanup and Disk Defragmenter (now Optimize Drives)—to help speed up your PC and free up precious storage space.
In this guide, we’ll walk you through how to use both tools effectively for a faster, more responsive computer. We’ll also explain why these tools are essential for keeping your system in top shape and help beginners navigate through every step.

What Are Disk Cleanup and Disk Defragmenter, and Why Should You Use Them?
Before diving into the step-by-step instructions, it’s important to understand what each tool does and how they contribute to the overall performance of your computer.
Disk Cleanup
Disk Cleanup is a Windows utility designed to remove unnecessary files from your system. These files can include temporary files, system files, cache data, and more, which take up valuable space on your hard drive. As your system accumulates these files, performance can degrade over time. Regularly running Disk Cleanup ensures that your computer has more free space, making it run more smoothly.
Disk Defragmenter (Optimize Drives)
Disk Defragmenter, now known as Optimize Drives, is another utility that helps organize the fragmented data on your hard drive. When files are saved, they can become fragmented, meaning they are split into multiple pieces and stored in different locations on your drive. This causes the system to work harder and slower as it searches for the different parts of the file. By using Disk Defragmenter, you can reorganize these files so they’re stored more efficiently, allowing faster access and improving performance.
Step 1: How to Use Disk Cleanup for Better Performance
Let’s begin with Disk Cleanup, which is often the easiest and quickest way to regain space and improve system performance.
1.1 Opening Disk Cleanup
To access Disk Cleanup, follow these steps:
- Press the Windows Key: On your keyboard, press the Windows key to open the Start menu.
- Search for Disk Cleanup: Type “Disk Cleanup” into the search bar.
- Launch the Tool: From the search results, click on the Disk Cleanup app to open it.
1.2 Selecting the Drive to Clean
Once Disk Cleanup is open, it will prompt you to select the drive you wish to clean.
- Choose the Drive: Typically, the C: drive is where the operating system and most of your files reside. If you want to clean other drives, you can select them from the drop-down menu.
- Click OK: Once you’ve selected the drive, click OK to proceed.
1.3 Scanning for Unnecessary Files
The Disk Cleanup utility will start scanning your drive for files that are safe to delete. This process might take a few minutes, depending on the size of your drive and how many files are stored.
- Wait for the Scan: The utility will evaluate your system and identify temporary files, system files, and other unnecessary data. This includes internet cache files, old Windows update files, and system error reports.
- View the Results: Once the scan is complete, you will be presented with a list of file categories that can be cleaned up.
1.4 Selecting Files to Delete
Here, you’ll see a list of file categories that can be deleted to free up space. These files can be safely removed without affecting the functionality of your system.
- Temporary Files: These are files created by your operating system or applications that are no longer needed. This can include installation files, program files, and other temporary files.
- System Files: These include files that Windows no longer requires but can still take up a significant amount of space.
- Recycle Bin: These are files you’ve deleted but haven’t yet permanently removed from the system.
- Windows Error Reports: These are diagnostic files generated when the system experiences an issue. Deleting them won’t affect your system.
- Download Program Files: Files downloaded by your browser or other programs that are no longer needed can also be safely removed.
1.5 Clean Up System Files
To free up even more space, you can clean up system files that are often hidden in the regular cleanup.
- Click “Clean Up System Files”: When the Disk Cleanup window opens, click the Clean up system files button.
- Wait for the Tool to Scan: The utility will scan for additional files, including previous Windows installations, Windows update files, and old system restore points.
- Select Files to Delete: Once the scan is complete, select the system files you want to delete (for instance, Windows Update Files or Previous Windows Installations).
- Click OK: Confirm that you want to delete these files, and click OK to begin the cleanup.
1.6 Confirm and Delete
Once you’ve selected all the files you want to delete, the tool will ask for confirmation.
- Delete Files: Click Delete Files to confirm. The cleanup will begin and may take a few minutes to complete.
- Wait for the Process to Finish: Allow the tool to finish its work. Afterward, your system will have more free space, potentially boosting performance.
Step 2: How to Use Disk Defragmenter (Optimize Drives)
While Disk Cleanup frees up storage space, Disk Defragmenter (or Optimize Drives) reorganizes fragmented files for faster access.
2.1 Opening Optimize Drives
To open Optimize Drives, follow these steps:
- Search for Optimize Drives: Open the Start menu and type “Optimize Drives” into the search bar.
- Select the Tool: Click on the Optimize Drives option that appears in the search results.
2.2 Analyze the Drive
Once the Optimize Drives window opens, you’ll see a list of all the drives on your computer. To begin optimizing, follow these steps:
- Select the Drive: Click on the C: drive (or whichever drive you want to defragment).
- Click Analyze: Click the Analyze button to check the fragmentation level of the drive.
- Wait for the Scan: The tool will scan the drive to determine how fragmented the files are. If the drive is less than 10% fragmented, optimization may not be necessary.
2.3 Optimize the Drive
Once the analysis is complete, it’s time to optimize.
- Click Optimize: If the fragmentation level is high, click Optimize to begin the defragmentation process.
- Wait for the Process to Finish: The defragmentation process may take a while, depending on the size of the drive and the fragmentation level. It could take anywhere from several minutes to a few hours.
2.4 Set Up Regular Optimization
For optimal performance, it’s a good idea to set up automatic optimization.
- Click “Change Settings”: In the Optimize Drives window, click Change settings.
- Choose a Schedule: You can set the tool to run Daily, Weekly, or Monthly. We recommend scheduling it for weekly use to maintain optimal performance.
- Click OK: Once you’ve chosen a schedule, click OK to save your settings.
2.5 Close the Tool
Once optimization is complete and the schedule is set, you can close the Optimize Drives window. Your hard drive will now be more efficient, and your system will have faster access to files.
Troubleshooting Common Issues
Disk Cleanup Not Working
- Ensure you have administrator privileges to run the tool.
- If the tool doesn’t find any files to clean, it could mean your system is already clean.
Defragmentation Not Starting
- Check whether you’re trying to defragment an SSD—SSDs don’t need defragmentation.
- Try running the tool as administrator if it doesn’t start.
FAQs (Frequently Asked Questions)
Q1: Can I defragment an SSD?
No, SSDs do not need defragmentation. In fact, defragmenting an SSD can reduce its lifespan because the process involves a lot of write operations.
Q2: How often should I run Disk Cleanup and Defragmenter?
- Disk Cleanup can be run monthly, or when you notice performance issues.
- Optimize Drives (Defragmenter) should be run every 1-3 months for traditional hard drives.
Q3: What if Disk Cleanup doesn’t show any files to delete?
If there are no files to delete, your system is likely well-maintained. However, running the tool as administrator can sometimes reveal hidden files.
