A while ago, I noticed my PC was getting slower almost every week. Programs took longer to open, startup times increased, and my hard drive constantly seemed close to full. At first, I thought it was just because my computer was getting older. But after checking my system, I realized I had dozens of unused programs installed that I never touched anymore.
Many of those apps were still running in the background, consuming memory, creating temporary files, and slowing everything down. That’s when I decided to tryIObit Uninstaller 15, a Windows uninstaller designed to completely remove unwanted software and leftover files. Surprisingly, after spending just a couple of minutes cleaning my PC, I immediately noticed smoother performance and more free storage space.
Why Unused Programs Were Slowing Down My PC
Before this, I assumed unused programs were harmless if I simply ignored them. I quickly learned that wasn’t true at all.
Even apps I never opened were still affecting my system in several ways:
– Running background processes that used CPU and RAM
– Adding startup entries that slowed Windows boot time
– Creating temporary files and logs that filled up storage
– Running scheduled update tasks silently
– Leaving outdated software on my system that could create security risks
Once I removed these unnecessary programs, my PC booted faster, applications opened more quickly, and the overall system felt much more responsive.
How I Removed Unwanted Programs in Just 2 Minutes
What I liked most about IObit Uninstaller 15 was how simple the cleanup process felt. Instead of manually uninstalling programs one by one, everything was organized clearly and optimized for faster cleanup.
Step 1 — Reviewing Installed Programs
When I opened this uninstaller for Windows, the first thing I saw was a full list of installed software on my PC. The All Programs section made it easy to review everything quickly. I could sort programs by: Size and Install date. I personally found the smart categories extremely helpful, especially: Large Programs, Recently Installed, Bundleware, Infrequently Used. These categories immediately helped me identify software I no longer needed without wasting time scrolling through endless lists.
Step 2 — Batch Removing Multiple Programs
One feature that saved me the most time was the ability to uninstall multiple programs simultaneously. Instead of removing software individually through Windows settings, I simply selected multiple unwanted programs and clicked the Uninstall button once. Compared to the default Windows uninstaller, this made the entire cleanup process dramatically faster and easier.
Step 3 — Cleaning Leftover Files Automatically
After uninstalling software manually in the past, I often discovered leftover folders, registry entries, and junk files still sitting on my system. This time, IObit Uninstaller automatically scanned for leftover data after each uninstallation and removed it completely.
The cleanup report showed exactly what was deleted, including useless registry entries, leftover files and folders, invalid scheduled tasks, and temporary uninstall data. In one cleanup session alone, I recovered several gigabytes of storage that I didn’t even realize were being wasted.
Checking Software Health Improved Things Even More
After removing unwanted programs, I also used the Software Health feature for a quick system check. This scan helped me find:
– Leftover traces from older uninstallations
– Outdated software with potential vulnerabilities
– Temporary software files
– Privacy traces
– Apps that could be put into sleep mode for better performance
– Annoying pop-up notifications and browser alerts
The scan only took a short time, but it helped optimize my PC even further.
I Also Cleaned Up Browser Extensions
One thing I had completely overlooked before was browser extensions. Over time, I had accumulated many unnecessary extensions across Chrome, Edge, and Firefox. Some were slowing down my browser, while others probably collected more data than necessary.
IObit Uninstaller included a dedicated Browser Extensions Manager, which let me review all installed browser add-ons in one place. I simply selected the extensions I no longer needed and removed them within seconds. Afterward, my browser definitely felt faster and less cluttered.
Removing Unwanted Windows Apps Helped Too
I also realized Windows comes with many built-in apps I never actually use. Apps like Cortana, Game Bar, and Microsoft Pay. They were still running background processes even though I rarely opened them.
Using the Windows Apps section inside IObit Uninstaller, I removed several unnecessary built-in apps quickly and easily. Even though some apps were small in size, disabling their background activity helped reduce system resource usage and improved startup performance slightly.
My Simple 2-Minute PC Cleanup Routine
After seeing how much difference this made, I started following a quick cleanup routine every few weeks. Here’s the process I personally use now:
1.Open IObit Uninstaller
2.Check the “Infrequently Used” category
3.Review “Large Programs” for storage-heavy apps
4.Batch uninstall unwanted software
5.Review leftover cleanup results
6.Run a Software Health scan
7.Remove unused browser extensions
The entire process usually takes only a few minutes, but it keeps my PC running much smoother over time. I especially noticed the difference on older systems with limited RAM or slower storage drives.
Final Thoughts
I honestly didn’t realize how many unused programs and leftover files were quietly slowing down my PC until I finally cleaned everything properly. After using IObit Uninstaller 15, I recovered storage space, reduced background processes, improved startup speed, and made my computer feel much more responsive overall.
What I liked most was that the software didn’t just uninstall programs — it also removed leftover files, registry clutter, browser junk, and hidden traces that Windows usually leaves behind. From my experience, spending just a couple of minutes removing unwanted software regularly can make a surprisingly noticeable difference in your PC’s speed and performance.
