Do you feel nostalgic when you see someone working on a PC where the apps launch quickly, and there is no low storage space notification? You’re not alone. After a year or so, and sometimes even after a shorter duration, most users with regular PC usage complain about slow startup, increased file access time, background processes consuming too many system resources, etc. You are wrong if you think this happens as the PC is getting old. Usually, this happens because of hidden junk files, background clutter, and invalid registries that build up silently, draining your PC’s performance like a slow leak in a tire, due to which you face a flat tire.
This is where a good PC cleaner comes in—a digital tune-up tool that helps identify, clear, and optimize your system to enjoy smooth performance.
We’ve tested 10 of the best PC cleaner tools for Windows—but this time, it’s done with a twist. The tests were conducted using trial versions, as most users do before paying for the software or anything.
Why We Used Trial Versions?
No one likes to pay upfront without trying. Similarly, when it comes to PC optimization tools, instead of using the paid version this time, we thought of using the trial versions. As this gives you a better understanding of –
- Features you can try before purchasing.
- Effectiveness of free tool in real-life scenarios.
- Understanding of whether the tool is worth investing in or not.
What is a PC Cleaner Software?
It is a tool designed to declutter your system, boost speed, improve FPS and game performance, keep drivers updated, clean the registry, and periodically optimize the PC.
A good PC cleaner helps:
- Remove unnecessary files that take up unnecessary disk space.
- Optimize system performance by managing and helping remove potentially unwanted startup programs and processes.
- Fixes registry errors that are potentially the reason for Windows crashes and slowdowns.
- Boosts gaming performance by freeing up RAM and CPU power.
- Update device drivers.
- Keeps the PC protected from threats and helps remove privacy-exposing traces.
Why Do You Need PC Cleaner Tool – The Cost of Slow PC
Working on a slow PC is like turning even simple tasks into marathons. It’s not just annoying; it’s costly. Research shows that a slow computer decreases productivity; on average, a person wastes up to 1.8 hours per week waiting for it to respond.
A PC that slows down for 5 minutes hourly can cause productivity loss of almost 3 hours weekly and 145 hours yearly.

A PC cleaner will help boost speed and add some extra years to your system life.
How We Picked the Best PC Cleaners?
We did not pull a lucky draw to pick these PC optimizers. Each software on this list was tested on a Windows 11 system used by everyday users. We checked not only how well they cleared junk files but also how much RAM they optimized and how they boosted startup speed.
Here’s what we paid attention to during our hands-on testing:
- How well the software removes unnecessary files.
- Before and after differences in boot time and application performance.
- Efficiency in cleaning browsing data, securely wiping deleted files, and keeping your PC secure from threats.
- How efficiently outdated drivers are identified and updated in the real time.
- Background processes and optimized memory management
- Startup Management to identify the programs slowing down PC.
- How can beginner and advanced users use the software, and what features are available in the trial version?
- Free vs. premium features, money-back guarantee, and customer support.
Test Environment
We used a moderately used PC with the following configuration for testing:
- OS: Windows 11 (64-bit)
- Processor: Intel Core i5
- RAM: 8 GB
- Storage: 512 GB SSD
Each tool was installed, scanned, and benchmarked using before-and-after comparisons of boot time, RAM usage, CPU load, and junk file removal.

Rated 4.8/5 on G2
Money Back – 60-day
When it comes to PC cleaners, most trial versions offer basic cleanup features like removing temporary files or freeing up disk space. But Advanced System Optimizer goes beyond just that. It’s a feature-packed toolkit that not only cleans junk files but also defragments your disk, updates outdated drivers, recovers lost data, safeguards privacy, and even offers a dedicated gaming mode to enhance gameplay performance.
What impressed us most during testing was its Driver Updater and System Cleaner modules. These tools managed to find outdated drivers and hidden junk files that were slowing down our system — things we weren’t even aware of.

Advanced System Optimizer is also AppEsteem certified, which means it meets global standards for safe, consumer-friendly software. Its Registry Cleaner & Optimizer fixes invalid entries that can impact stability, while the Disk Defragmenter organizes fragmented files to boost read/write speeds.
Beyond performance, the tool offers excellent security features. Tools like Secure Delete, Undelete, Privacy Protector, System Protector, and more work together to keep your data private and safe. Secure Delete permanently wipes sensitive files, Privacy Protector clears browsing history and cookies, and System Protector scans for threats — adding an essential layer of security. And for gamers, the built-in sandbox mode ensures uninterrupted gaming sessions without resource-hogging apps interfering in the background.

Rated 3/5 by TechRadar
Money Back – 30 days
Iolo System Mechanic justifies its name. It works like a skilled mechanic who knows exactly where to look for issues. Unlike superficial cleaners, it digs deep to scan for privacy traces, Windows system errors, and memory leaks. The only limitation is the trial version can’t clean invalid registry entries, provide full PC security, or unlock the password manager features.

Its standout Startup Manager reveals precise boot delay times (measured in seconds), helping eliminate unnecessary startups – we even caught a disguised Bitcoin miner from 2018 during testing!

As you keep using the PC without your knowledge, it becomes a digital packrat and accumulates files you don’t need, running idle apps in the background that you forgot to shut down, and much more.

5. AVG Tuneup
Best for: Routine system maintenance
Rated – 3/5 PCMag
Money Back – 30-day
After spending weeks testing PC cleaners for this 10 best PC cleaner software, AVG TuneUp is a simple-to-use cleanup tool. It is well-categorized and displays results in a very clear manner. You can easily know the amount of junk files on the system, the number of programs to update, the processes to turn off to boost speed, etc. For 7 days, it lets you try its powerful features and see a performance boost. However, there is no security module to scan the PC for threats like you have in Advanced System Optimizer. However, if you are using AVG Tuneup, you cannot use Avast products as they interfere with one another.
Whatever the case, AVG TuneUp saved me from 3 vulnerable Java versions, while its Browser Cleaner removed 1,700+ tracking cookies the “Scheduled Cleanings” helps keep PC optimized and the user interface is clean offering detailed explanations for each feature.
The Automatic Maintenance mode works silently in the background, and it helps free up enough space by deleting forgotten Windows Update files and Steam backups. Additionally, it completely uninstalls outdated or risky software and the deep clean helps clean duplicate photos and videos. Most cleaners overlook this, but AVG even compares content and it has nearly identical features with Avast. However, AVG has 50% fewer upsell pop-ups.

It is a modern tool designed to fix today’s bloated systems. The interface is clean and easy to use, and its AI Mode stands out. You can choose to scan the PC manually or use AI mode. The tool scans the PC for junk files, registry fragments, invalid shortcuts, outdated software, spyware threats, and many other problematic areas. It scans fast. However, you must upgrade to the Pro version to fully clean and optimize your PC.
When my PC used to slow down just before important meetings or gaming sessions? I used to feel like throwing away the device until I discovered Advanced SystemCare. It is not just another cleaner. Unlike CCleaner and other PC optimization tools it offers AI-powered optimization that helps clear RAM efficiently and reduce the load time.
The latest version includes real-time ransomware protection and it identifies a fake “invoice.pdf.exe” that most standalone security tools failed to detect. Also, it quickly finds Junk files and tracking cookies.
Compared with Wise Care 365 its ASC’s FaceID-like login protection prevents kids from messing with settings. Besides this the tool also helped me fix my daughter’s Roblox lag by allocating 90% GPU power to games automatically. It even silenced background apps and repaired broken network registry keys.

The trial version of Wise 365 has surprised me. It is lightweight yet fast with quick scans. The cleaning is intense without resource-hogging. Also, there is real-time monitoring even without paying. However, the interface is a bit outdated, and Wise Protection is locked behind the Pro version. For daily cleanup and silent system monitoring, it is the best tool.
The System Cleaner removes invalid Windows registry entries and cleans temporary files, browser caches, and download histories. Optimizes system settings to improve speed and stability, erases traces of activities performed and the System Monitor provides real-time insights into CPU, RAM, and disk usage.

When Microsoft launched its cleanup tool, there were many speculations, and most people thought it wouldn’t work.

The tool does basic cleanup, RAM cleaning, and startup app control for performance boost. You will be disappointed if you’re looking for deep cleaning or registry repair, as you won’t find it.
This completely free tool removed a good amount of temp files in 90 seconds during my testing and the startup impact analysis feature shows exactly which apps slow boot times.

After using different PC cleaners for this listicle, this tool fits in as, unlike other tools, it is neither heavy nor filled with ads or hidden costs. The tool does a simple job and focuses on simple cleanup. It cleared nearly 3GB of cached junk within seconds. It’s lightweight. However, no registry cleaner, startup optimizer, or deep system cleaning exists. It is a quick solution to clean basic clutter without paying.

Case Study: How a PC Cleaner Improved Performance?
Scenario: John, a video editor, noticed that his Windows 10 PC was not responding as quickly as it used to while rendering videos. Also, the boot time increased, and Adobe Premiere Pro lagged during editing.
To fix this, he used different PC cleaners and optimization software, out of which Deep Scan and Cleaning of Advanced System Optimizer outperformed as he was able to remove ~6GB of junk files, fix invalid and broken registries, and also was able to manage startup items that were slowing down the boot time.
Results After Optimization:
- Boot Time Before: 2 minutes 10 seconds → After: 48 seconds (60% faster!)
- Rendering Speed Improved by 25%
- Lag during editing was reduced by optimizing system processes.
