Junk file is a term used for files that are no longer useful but are still stored on the system, such as temporary files, cache, thumbnails, registry entries, and other unused files.

The garbage files that accumulate will burden the system and make Windows feel sluggish. It can also make the hard disk fill up fast. Anyway, trash files that are not cleaned diligently can cause problems for our Windows.

Therefore, in this post, I will provide some recommendations for the best PC cleaner applications in 2021 that can help you clean Windows from junk files to the roots.

Windows 10 Cleaner Applications For Free PC Laptop

#1. Storage Sense

This built-in feature of Windows 10 can be a tool to clean junk files without having to install additional applications. When enabled, Storage Sense can clean junk files automatically when the hard disk becomes full. We can adjust the frequency and determine how much remaining storage is until this feature does the cleaning automatically.

Storage Sense can also scan the hard disk to detect junk files such as cache and temporary files such as other cleaner applications. When you feel that the computer is starting to feel heavy and the remaining storage capacity (especially on drive C) is low then you can use this feature.

How to activate and use Storage Sense:

1. Open Settings.
2. Enter the System menu.
3. Select Storage.
4. Click on Configure Storage Sense or run it now.
5. Check to On in the Storage Sense section.
6. Choose an automatic cleaning schedule, I usually choose Every month (once a month).
7. Check on Delete temporary files, and select the cleaning schedule.
8. In the Delete files in the My Download folder, select Never.

You can also manually scan to clean junk files on your hard disk using Storage Sense, this is very useful for speeding up Windows 10 as a whole. The trick is to click the Clean Now button on the bottom menu of Storage Sense.

Wait until the scan is complete, then click the Clean Now button again to make sure the junk files have been cleaned completely.

Pros and cons of using Storage Sense:

Advantages:

• No need to install additional applications.
• No ads, no bloatware.
• Do not burden the system when scanning.
• 100% free and malware-free.
• Can do cleaning automatically.

Deficiency:

• Limited features.
• Cannot perform deep scans.
• Can only clean temporary files and cache.
• Cannot clean registry.
• Only on Windows 10.

#2. CCleaner

The second best cleaner application for Windows is CCleaner. This application can clean various kinds of junk files ranging from the cache, temporary files, thumbnails, and registry entries, to the browser tracker. The free version is good enough to use on a personal computer.

CCleaner also comes with features that are complete enough to optimize the Windows that we use. By using this application we can clean the hard disk thoroughly, clean cache files and tracker on the browser, scan the registry, and uninstall the application until it is clean.

The Duplicate Finder feature in CCleaner can also detect duplicate files on the computer and clean them. We can also do a thorough scan on the computer to clean up leftover junk files from Windows Explorer activity.

Installing the CCleaner application may be one of the things that must be done after installing Windows 10 because its function is quite important to keep the system clean and light.

This application can be installed for free, but if you want to get more complete features you can buy a pro version license. Please download the CCleaner application from the following link:
