Do you remember how fast your Windows PC felt when you first bought it? If your computer now takes minutes just to boot up or stalls every time you open a browser, you are not alone. Over time, Windows collects digital clutter, which slows your system to a crawl.

Fortunately, you don’t need to spend money on upgrades or expensive cleaning software. As PMN Online and pmntechfix.nl, we specialize in the fixes you can do right now.

Here are 5 proven, free steps you can take today to dramatically speed up your Windows PC.

Step 1: Disable Unnecessary Startup Programs (The Biggest Culprit)

The number one reason your computer takes so long to boot is because it’s trying to load dozens of apps the moment you log in. Most apps sneakily enable themselves to start automatically.

The Fix: Taming the Task Manager

1. Press Ctrl + Shift + Esc simultaneously to open the Task Manager.
2. Click on the “Startup” tab.
3. Look at the “Startup Impact” column. Anything labeled “High” is slowing you down the most.
4. Right-click on any program you don’t need running immediately (e.g., Spotify, Steam, printer software, old chat apps).
5. Select “Disable.”

⚠️ Pro Tip: Only disable apps you recognize. Leave anything related to “Microsoft,” “Windows,” or “Drivers” enabled to avoid system instability.

Step 2: Clear Temporary and Junk Files with Disk Cleanup

Every time you browse the web, install an update, or open a document, Windows stores temporary files. These files accumulate over months and can waste gigabytes of space, sometimes impacting performance.

The Fix: Using the Built-In Disk Cleanup Utility

1. Type “Disk Cleanup” into the Windows Search bar and open the app.
2. Select your primary drive (usually C:) and click “OK.”
3. A window will appear listing file types. Check the boxes next to files you want to delete. The most important ones are:
   • “Temporary Internet Files”
   • “Temporary files”
   • “Recycle Bin”
   • “Delivery Optimization Files”
4. For maximum cleaning, click the “Clean up system files” button, then re-select the C: drive and check any new options that appear (like “Windows Update Cleanup”).
5. Click “OK” and then “Delete Files.”

Step 3: Identify and Close Resource-Hogging Apps

Sometimes your PC suddenly slows down in the middle of a work session. This is often caused by a single app eating up all your processing power or memory (RAM).

The Fix: Diagnosing Real-Time Usage

1. Press Ctrl + Shift + Esc to open Task Manager again.
2. Stay on the “Processes” tab.
3. Click the column headers for “CPU” and “Memory” to sort them from highest to lowest usage.
4. If you find an application that is using a high percentage of CPU or Memory and you are not actively using it, right-click on it and select “End task.”

Example: You might find a web browser tab or a background sync application using 80% of your CPU. Ending that task will immediately free up resources.

Step 4: Uninstall Unused Programs (Digital Spring Cleaning)

Do you have software you installed years ago and haven’t touched since? Not only do these waste storage space, but they can also sometimes run background processes that slow your system down.

The Fix: Deleting Bloatware and Unused Apps

1. Type “Add or remove programs” into the Windows Search bar and open the system setting.
2. Scroll through the list of installed applications.
3. If you find a program you haven’t used in months or years, click on it and select “Uninstall.”

Step 5: Check for Malware and Adware (The Hidden Performance Killers)

A persistent performance problem that doesn’t go away after the above steps may be caused by unwanted software—malware, viruses, or adware—that secretly runs background tasks.

The Fix: Running a Deep Windows Defender Scan

1. Type “Windows Security” into the search bar and open the app.
2. Click on “Virus & threat protection.”
3. Click on “Scan options.”
4. Select “Full scan” to perform a deep check of your entire system. This will take longer (up to an hour or more), but it’s the most thorough way to find hidden threats.
5. Once the scan is complete, follow the prompts to remove any identified threats.
