PC Running Slow? Ultimate Fixes to Speed Up Windows 10 & 11 Fast
A slow computer can be incredibly frustrating. Whether your apps take too long to open, the system freezes randomly, or the entire PC lags during simple tasks, performance issues can ruin your workflow. Windows 10 and Windows 11 are powerful operating systems, but over time, they can slow down due to software, storage, or hardware problems.
In this guide, WinTechSupport, the best technical support company, explains why your PC slows down and how to speed up Windows quickly using proven, safe, and effective methods.
Why Your PC Becomes Slow Over Time
Several factors contribute to performance issues:
- Too many startup programs
- Low RAM or heavy background tasks
- Malware or virus infections
- Outdated software or drivers
- Fragmented hard drives (HDD)
- Low disk space
- Old or failing hardware
- Windows update issues
Once you identify the cause, optimizing your system becomes much easier.
1. Disable Unnecessary Startup Programs
Many applications automatically start when you turn on your PC, slowing down boot time and consuming resources.
How to fix:
- Press Ctrl + Shift + Esc
- Go to Startup tab
- Disable apps you don’t need at startup
This alone can significantly speed up Windows boot performance.
2. Uninstall Programs You Don’t Use
Old software, trial versions, and unused apps consume disk space and background resources.
Steps:
- Open Settings → Apps → Installed apps
- Remove heavy or unnecessary software
Freeing up space improves system responsiveness instantly.
3. Clear Temporary Files
Windows stores temporary files that pile up and slow the PC.
Clean temp files:
- Press Windows + R → Type temp, %temp%, and prefetch
- Delete all files inside
Or use Storage Sense in Windows 10/11 to automate cleanup.
4. Update Drivers and Windows
Outdated drivers—especially graphics, storage, and chipset—can cause lag and freezing.
Update through:
- Device Manager
- Windows Update
- Manufacturer tools like NVIDIA/AMD/Intel
Updates improve compatibility, performance, and stability.
5. Scan for Malware or Viruses
Malware is a major reason PCs become slow. It consumes CPU, RAM, and internet bandwidth.
Fix:
Run a full system scan using Windows Security or a trusted antivirus tool.
If malware persists, WinTechSupport technicians can safely remove deep-rooted infections without harming your data.
6. Increase Virtual Memory (Paging File)
If your PC has low RAM, increasing virtual memory helps prevent freezing.
Steps:
- Go to System → Advanced system settings
- Under Performance, click Settings
- Open Advanced → Virtual memory
- Set a custom size (recommended: 1.5x your RAM)
This improves stability when running multiple apps.
7. Use the Built-in Performance Troubleshooter
Windows 10 and 11 include tools to automatically detect slow performance issues.
Use:
Settings → System → Troubleshoot → Other troubleshooters → Performance
8. Upgrade Hardware (RAM or SSD)
If your PC is still slow after software optimization, outdated hardware may be the issue.
- Upgrade RAM for multitasking
- Replace HDD with SSD for instant speed boost
- Ensure your system has enough cooling
An SSD alone can make an old PC feel brand new.
9. Clean Your PC Physically
Dust buildup causes overheating, leading to automatic slowdowns.
Fix:
- Clean air vents
- Use compressed air
- Ensure proper ventilation
Cooler systems perform faster and last longer.
