This beginner-friendly guide will walk you step by step on how to fix a slow Windows PC.
Why Does a Windows PC Become Slow?
Before fixing the issue, it’s important to understand the causes. A slow PC doesn’t always indicate a serious problem—sometimes, it just needs maintenance.
Common reasons why Windows PCs slow down:
- Too many startup programs
- Low storage space
- Old or fragmented hard drive
- Outdated Windows updates
- Malware or viruses
- Too many junk/temporary files
- Heavy background processes
- Old or insufficient RAM
Now that you know the causes, let’s move on to the solutions.
Step-by-Step Guide to Speed Up Your Windows PC
Step 1: Restart Your PC
Restarting clears your system memory, closes unused programs, and refreshes Windows. If your PC has been running for days without a restart, this simple step can make it feel faster.
Step 2: Turn Off Startup Programs
Many apps automatically start when Windows boots, slowing down your system.
How to disable startup apps:
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to the Startup tab.
- Disable unnecessary apps (e.g., chat apps, music players, third-party updaters).
Step 3: Clear Out Storage Space
Low storage, especially on the C: drive, can make Windows sluggish.
Tips to free up space:
- Empty Downloads and Recycle Bin.
- Uninstall apps you no longer use.
- Use Disk Cleanup to remove junk files.
Step 4: Update Windows and Drivers
Outdated software slows down performance.
- Go to Settings → Update & Security → Windows Update and install updates.
- Update your graphics, sound, and network drivers manually or using trusted software.
Step 5: Run a Virus & Malware Scan
Viruses and malware can significantly slow down a PC.
- Use Windows Defender or a trusted antivirus program.
- Remove threats immediately if found.
Step 6: Clean Temporary and Junk Files
Over time, unnecessary files pile up and slow down your PC.
To remove temp files:
- Press Windows + R, type and delete all files.
- Use a PC cleaner tool like CCleaner or Defencebyte PC Optimizer for automated cleaning.
Step 7: Adjust Visual Effects
Windows animations look nice but slow down older PCs.
- Right-click This PC → Properties.
- Click Advanced System Settings → Performance Settings.
- Select Adjust for best performance (or customize as needed).
Step 8: Stop Background Apps
Background apps use memory even when not in use.
- Go to Settings → Privacy → Background apps.
- Turn off unnecessary apps.
Step 9: Upgrade Hardware (If Necessary)
If your PC is still slow, it may be a hardware limitation.
- Upgrade to 8GB RAM or more for multitasking.
- Replace your old HDD with an SSD for a massive speed boost.
- Clean dust inside your PC to prevent overheating.
Step 10: Reset or Reinstall Windows (Last Option)
If nothing else works:
- Go to Settings → Update & Security → Recovery.
- Select Reset this PC.
This gives your PC a fresh start.
Extra Tips to Keep Your PC Fast
- Restart your PC at least once a week.
- Avoid installing unnecessary apps.
- Clear browser cache and cookies regularly.
- Keep your antivirus updated.
Defragment HDDs (not needed for SSDs).
