In 2026, I realized that keeping my PC clean isn’t just about managing files. Many applications take up several gigabytes of storage, modify the registry, add startup entries, install unwanted components, and yet, I barely use them. After testing multiple tools, I found IObit Uninstaller to be the best solution for batch uninstalling apps while also deeply cleaning leftover traces.
I’ve been using IObit Uninstaller 15, and here’s my honest experience with how it helps me keep my PC clean, fast, and clutter-free in 2026.
Why Batch Uninstalling Is a Must in 2026
Software today is heavier than ever. Bundled programs, old utilities, games, or creative suites can take up dozens of gigabytes. Often, I install applications and then never open them again.
The problem is:
- Regular uninstalls leave leftover files
- Registry entries pile up
- Background services keep running
- Over time, my disk space slowly shrinks
So, I decided to batch uninstall large and rarely used apps to free up space and boost system performance.
How I Batch Uninstall Large and Rarely Used Apps
Step 1: Identify Large and Rarely Used Programs
After installing this uninstaller for Windows, I opened the software uninstall interface. It’s neat and intuitive, showing program size, installation date, and usage frequency. I usually sort by Large Programs. This makes it easy to quickly identify the biggest space hogs on my system.
Step 2: Use Filters to Target Disk Space Hogs
Or I will use the Filter By Disk Drive feature to see which programs occupy space on my system drive. When my SSD is nearly full, this is extremely helpful. After selecting unused large programs, I can batch uninstall them in one go.
Step 3: One-Click Batch Uninstall
This is where IObit Uninstaller 15 really shines. I simply select several programs and click “Uninstall.” The new uninstall engine in version 15 is faster and more thorough than previous versions.
The 2025 update brought me some impressive features:
- A completely new uninstall engine
- Faster removal
- Deeper leftover scanning
After uninstalling, it scans and removes:
- Residual files
- Registry entries
- Hidden folders
I love that I can see exactly what’s being deleted on the results screen.
Step 4: Remove Stubborn Programs
Sometimes my apps won’t uninstall because of:
- Corrupt uninstallers
- Missing registry entries
- System restrictions
I use Force Uninstall+ and Stubborn Program Remover, which let me remove even problematic software easily. Version 15 supports 4,000+ difficult programs in the stubborn program database, and even broken installations get cleaned without leaving traces.
Step 5: Permanently Delete Sensitive Files
After uninstalling, I sometimes want to completely erase documents or installation files left behind. The File Shredder securely destroys files, making them unrecoverable. This is especially useful for:
- Confidential documents
- Old installation packages
- Sensitive work files
Step 6: Remove Browser Extensions and Windows Apps
Many people overlook unused browser extensions and pre-installed Windows apps. I’ve experienced slowdowns and wasted memory because of them. With IObit Uninstaller, I can remove the following:
- Extensions from Chrome, Edge, and Firefox
- Microsoft Store apps
- Built-in Windows apps
This keeps both my system and browser lightweight.
Step 7: Turn on the Auto Monitor Feature for Future Installations
When I uninstall the program later, everything recorded gets removed, leaving my system as if the program had never been installed—a true clean uninstall. For someone like me who tests software often, the Install Monitor feature is a lifesaver. It tracks all system changes during software installation:
- Startup entries
- Scheduled tasks
- System services
- DLL registrations
Step 8: Clean Hidden Software Impact with Software Health
At last, to make my system feel faster, smoother, and safer, version 15’s Software Health feature helps me clean residual setup files and hidden issues:
- Remove leftover installation files
- Manage hidden permissions
- Block intrusive pop-ups
- Clean redundant files
- Remove malicious extensions
My Results (Windows 11 Testing)
- Apps removed in one batch: 8 large unused programs
- Disk space freed: 3.6GB
- Faster startup after cleanup
- Noticeable system responsiveness improvement
- Silent uninstallation made the whole process automated and simple
