How to Clean Up Your Computer

Let’s walk through the step-by-step plan of cleaning your PC to make it faster:

Method 1: Automate your PC cleanup with Auslogics BoostSpeed

All the points we will discuss further do a fair job of cleaning your system, but each of these methods has its disadvantages. Plus, you have to do it manually, one step after the other, which can be time-consuming.

The best way to fix this is to use Auslogics BoostSpeed—one software to rule them all.

Forgive the Tolkien reference, but this program has so many features to keep your PC running at its peak performance for years to come! 

Here’s how BoostSpeed can help you clean your computer for good:

Windows Slimmer

If you want to know how to clean up your computer the right way, use the Windows Slimmer feature in Auslogics BoostSpeed. 

The software is designed to sweep out all kinds of PC junk, like residues of Windows Update files, temporary files, Java files, Microsoft Office cache you don’t need, and a lot more. 

• Just download the software from the official page, run it, and select All Tools. Then, click on Windows Slimmer. 

• In the next window, you can select One-Time Maintenance or Regular Maintenance. Regardless of the option you choose, you can select Show details to explain what each section will delete. 
• You also have the option to check or uncheck the boxes according to your preference. When you’re done, click Start Scan. 

• When the analysis is complete, select Start Cleanup to delete all the temporary files or folders you don’t want. 

Disk Defrag

This feature makes the computer clean up effortlessly by piecing together scattered files and preventing further defragmentation. 

What’s more special is that you can defrag your SSD or HDD without any issues.

Auslogics Disk Defrag uses a unique algorithm to defragment your files and save more space. And it comes with no consequences or downsides. 

Here’s how the process works: 

• Run the program and click on Disk Defrag. 

• Click the arrow pointing down to Analyze, Defrag, Defrag & Optimize, or Quick Defrag (without analyzing) to start the process. That’s it! 

Registry Cleaner

BoostSpeed’s Registry Cleaner even takes a deeper dive into the heart of your PC. It deeply analyzes and fixes any problem in your Windows Registry. 

This is important because cleaning your system manually can destabilize it or lead to the loss of some functionalities (which I’ve experienced myself). 

If you want to clean your registry: 

• Launch BoostSpeed, search for “Registry Cleaner” on the slide bar, and click on it.
• Check the files you want to clean and select Scan Now. 

Duplicate File Finder

This tool is designed to search for and remove duplicate files to get more disk space on your computer. It scans your photos, audio files, videos, documents, and even program files. 

Duplicate File Finder uses a smart algorithm to differentiate not only file names but also their contents for accurate results. 

Here’s how to clean up a PC using the tool: 

• Run the BoostSpeed program, search for Duplicate File Finder on the bar, and click on it. 
• Check the file types you want to look for and select the Search button. 

SSD Optimization

As the name implies, the SSD Optimization tool is specifically designed to boost the longevity and performance of your solid-state drive. 

This feature turns on the TRIM command to help the drive manage unused data efficiently. In other words, the disk can perform write operations faster and increase the SSD’s lifespan. 

Also, it disables any services it doesn’t need and, checks and installs firmware updates. 

Now, let’s move forward and explore what we can do with the integrated Windows tools to clean up your PC.

It’s important to mention once again that each method described below requires your attention and manual actions.

Method 2: Delete junk files

Clearing your old temporary files is a great place to start with your computer cleanup. There are two ways to do this. Let’s quickly go through them: 

Use Disk Cleanup to clean up computer 

• Go to your Windows search bar, type “disk cleanup,” and select the relevant results. 

• Search the files you want to delete, tick the boxes, and click OK. 

• If you want to clean your temporary system files, click on Clean up system files, choose the files you don’t want, and click OK. 

Use the Settings window 

• Press Windows + I on your keyboard to open the Settings app. 
• Click on System and select Storage. 

• Search for Temporary files and click on it. 

• Finally, select the boxes you want to delete and click on Remove files.

Method 3: Clean bloatware from your system

Let’s face it. One of the worst (and frankly annoying) parts about buying a new PC is the pre-installed bloatware.

I get that manufacturers do this to keep their prices down, but it’s still taking up space. Besides, you might never use these applications.

So if you haven’t set a time to uninstall these programs, you should. You can learn how to clean up PC bloatware by:

• Searching for the apps in the Settings app and deleting them. 

Just search for the programs and delete them manually. 

• Using software like Win11Debloat or Windows10Debloater. 

For Windows 10, right-click on any icon in the file and select Run with PowerShell after downloading. It’ll automatically delete the bloatware for you. With Windows 11, extract the ZIP file after the download and double-click the Run.bat file. When Windows PowerShell opens, type “1” or “2” according to your preference and press Enter to start the process. 

• Performing a clean install 

This is a good option if you just bought your PC or have already planned to reset your system. If you want to know how to clean up a computer to run faster, this option usually works. However, regardless of its subjectiveness, some programs can pose security threats. So, always be on the lookout.

Method 4: Clean your Windows Registry

The system registry is one of the key places to remove entries if you want to know how to clean up a computer. After all, it’s like the brain of your PC.

Make sure to delete the programs before proceeding with this step. This method particularly deletes the entries of uninstalled software. 

Here’s how to clean up a PC using the registry:

• On your keyboard, press Windows + R to open the Run window.
• Then type “regedit” and press Enter to open the Registry Editor.

• Click File and select Export.

• Select where you want to save the backup and click Save.

• Double-click HKEY_CURRENT_USER to expand it. Then, click the arrow beside SOFTWARE to open it. 

• Look through the entries for the apps you’ve deleted. Then, right-click on it and select Delete. 

Method 5: Delete duplicate files

Duplicate files have a way of sneaking up on you, taking up lots of space, and sometimes slowing your Windows PC down. The more you download the same file types over and over again, the more duplicates you create. 

Windows doesn’t have a dedicated tool to remove duplicate files, but you can still do it manually if you have the time. You can sort files by name or size in the File Explorer. This makes it easy to find duplicate files. 

You can also use Windows Photos to search for duplicate photos. However, the best option is to use third-party software to automate the process.

You can use Auslogics Duplicate File Finder, Fast Duplicate File Finder, CCleaner, and more. Just run any of these programs, and it’ll automatically search for duplicate continents for deletion.

Bonus Method: Defragment your drive

If you save large files in limited free space, your system will store them in the nearest available space. As a result, different parts of the same file may become separated, causing fragmentation.

Defragmentation is a process used to increase a computer’s efficiency by rearranging data that has become scattered across the hard drive.

Luckily, Windows has a built-in tool to defragment your HDD or SSD. 

Just go to your search and type “Defragment and Optimize Drives” and hit Enter. A window will open, then choose your drive and click Optimize.

The downside, however, is that it can take a long time to defrag, especially if your hard drive is old. Furthermore, it can prematurely wear out your SSD, and it’s generally not accepted to defrag them.
