Keeping a Windows 10 PC free from junk files is one of the simplest ways to improve speed, free up disk space, and maintain system stability. Over time, your computer collects temporary files, cached data, and leftover program files that can slow things down. For beginners, learning the right methods to remove these unwanted files can make a noticeable difference.
What are junk files and why should they be removed?
Junk files are temporary or unnecessary data created by Windows and applications during normal use. Common types include system temporary files, browser cache, Windows update leftovers, and error logs. While each file alone may seem small, together they can take up gigabytes of space. Removing junk files improves performance, prevents file clutter, and helps your computer boot faster.
How can you remove junk files using built-in Windows tools?
Windows 10 includes several built-in utilities that can safely delete most types of junk files.
1. Disk Cleanup
Disk Cleanup is the easiest starting point. To open it, type “Disk Cleanup” in the Start menu search box and select the tool. Choose the drive you want to clean (usually C:), and let it scan. It will list categories like Temporary Internet Files, Delivery Optimization Files, and Recycle Bin. Check the boxes and click OK to delete them. This tool is safe for beginners because it only removes files Windows no longer needs.
2. Storage Sense
Storage Sense automates cleanup. Go to Settings > System > Storage, and turn on Storage Sense. Then click “Configure Storage Sense or run it now.” You can choose how often it runs and what it deletes, such as temporary files or Recycle Bin contents older than a set number of days. This feature helps maintain a clean system automatically without manual effort.
3. Manual cleanup of temporary folders
Some temporary files remain outside of Disk Cleanup’s reach. You can safely delete them manually.
a. Press Windows + R to open the Run dialog.
b. Type %temp% and press Enter.
c. Select all files in the folder and delete them.
d. Repeat by typing temp (without %) in the Run dialog.
These folders store application and system temporary data that can be removed after use.
Which third-party tools make junk removal easier?
While Windows tools are helpful, dedicated cleanup utilities can go further by identifying leftover registry entries, broken shortcuts, and hidden junk files.
Glary Utilities is a highly recommended all-in-one maintenance tool for Windows 10. Its 1-Click Maintenance and Clean Up & Repair modules simplify cleanup for beginners. For example, by opening Glary Utilities and selecting “1-Click Maintenance,” you can scan for temporary files, invalid shortcuts, and system junk in one step. The Clean Up & Repair section includes Disk Cleaner and Registry Cleaner, which dig deeper into areas that Windows’ built-in tools often miss.
A key advantage of Glary Utilities is its safe design. It creates automatic backups before making changes, so users can easily restore the system if needed. This makes it ideal for beginners who want deeper cleaning without risk.
How can you maintain a cleaner system going forward?
Once junk files are removed, keeping your PC clean is about consistency. Running Disk Cleanup or Glary Utilities’ 1-Click Maintenance weekly helps prevent buildup. Avoid installing unnecessary software, and periodically empty the Recycle Bin. Enabling Storage Sense ensures that temporary files are removed in the background without manual effort.
For beginners, combining Windows’ built-in tools with Glary Utilities offers a balanced and safe strategy for junk file removal. Regular cleanups not only free up space but also help your Windows 10 computer stay smooth, responsive, and reliable over time.
