Windows computers are known for their versatility, but over time, even the fastest machines can slow down, freeze, or become unresponsive. Troubleshooting performance issues doesn’t have to be overwhelming—with the right strategies, you can quickly identify root causes and fix them, saving precious time and restoring your PC’s speed. In this guide, we’ll cover the 12 most effective Windows performance troubleshooting strategies, focusing on actionable steps and practical Clean Up & Repair tips that work for both beginners and advanced users.
1. What Programs Are Slowing You Down? Check and Manage Startup Items
Beginner steps:
– Press Ctrl + Shift + Esc to open Task Manager.
– Switch to the ‘Startup’ tab.
– Disable unnecessary programs (right-click and choose ‘Disable’).
Advanced tip:
Some background services are less obvious. Use the Autoruns tool from Microsoft’s Sysinternals suite to spot hidden startup entries and disable them.
Glary Utilities makes this easy with its Startup Manager, allowing one-click control over startup programs for faster boot times.
2. Are Junk Files Hogging Your Hard Drive? Run a Cleanup
Beginner steps:
– Open Settings > System > Storage and turn on “Storage Sense” to automatically clean up temporary files.
Advanced tip:
Use Windows’ built-in Disk Cleanup (search “Disk Cleanup” in the Start menu) and select system files for deeper cleaning, including old Windows updates.
For a more thorough job, Glary Utilities offers a Disk Cleaner and a Temporary Files Cleaner that clear hidden leftovers and free up gigabytes of space in minutes.
3. Is Your System Outdated? Keep Windows and Drivers Updated
Beginner steps:
– Open Settings > Windows Update and check for updates.
– Install all pending updates.
Advanced tip:
Update drivers via Device Manager, or use manufacturer tools for graphic cards and chipsets for best performance.
Glary Utilities includes a Software Update Checker that helps you keep third-party software up-to-date as well.
4. Is Your Hard Disk a Bottleneck? Defragment or Optimize Drives
Beginner steps:
– Search for “Defragment and Optimize Drives” in the Start menu.
– Select your hard drive and click “Optimize.”
Advanced tip:
Solid State Drives (SSDs) don’t require defragmentation but benefit from the TRIM command, which Windows handles automatically. For mechanical drives, regular defragmentation improves speed.
Glary Utilities has a Disk Defrag tool that schedules and optimizes both hard drives and SSDs intelligently.
5. Are Resource Hogs Draining Performance? Monitor with Task Manager
Beginner steps:
– Open Task Manager (Ctrl + Shift + Esc).
– Check which applications use the most CPU, Memory, or Disk.
Advanced tip:
If you notice persistent high usage from background processes, check for unnecessary background services or malware.
Glary Utilities’ Process Manager provides a more detailed view and allows quick termination or prioritization of resource-intensive processes.
6. Is Malware Slowing Down Your PC? Scan and Remove Threats
Beginner steps:
– Run a full security scan with Windows Security (Defender).
– Remove any detected threats.
Advanced tip:
Use a reputable third-party scanner for a second opinion. Malwarebytes is a popular choice.
Glary Utilities includes a Malware Remover that adds another layer of protection and can find stubborn threats missed by built-in tools.
7. Are Your System Settings Optimized? Adjust for Best Performance
Beginner steps:
– Control Panel > System > Advanced system settings > Performance Settings.
– Choose “Adjust for best performance” or manually uncheck fancy visual effects.
Advanced tip:
Fine-tune individual effects for a balance between appearance and speed based on your hardware.
Glary Utilities’ 1-Click Maintenance includes performance tweaks that automate safe changes for optimal speed.
8. Is Your Registry Clean and Healthy? Repair Registry Errors
Beginner steps:
– Avoid editing the registry manually unless you know what you’re doing.
Advanced tip:
Use Glary Utilities’ Registry Cleaner to safely scan and fix registry errors, which can reduce crashes and system hiccups.
9. Are Background Apps Using Bandwidth and Resources? Limit App Activity
Beginner steps:
– Settings > Privacy > Background apps, and turn off apps that don’t need to run in the background.
Advanced tip:
Disable unnecessary scheduled tasks using Windows Task Scheduler or Glary Utilities’ Startup Manager.
10. Is Low Disk Space Affecting Performance? Free Up Space
Beginner steps:
– Empty the Recycle Bin and uninstall unused applications (Settings > Apps > Apps & features).
Advanced tip:
Move large files to an external drive or cloud storage. Use Glary Utilities’ Disk Analyzer to identify and remove space hogs.
11. Are Power Settings Restricting Performance? Adjust Power Options
Beginner steps:
– Control Panel > Power Options, and select “High performance” (if available).
Advanced tip:
Customize advanced power settings for processor state, sleep, and more to match your usage habits.
12. Is Your Hardware Up to the Task? Evaluate Upgrade Options
Beginner steps:
– Check system specifications (RAM, CPU, storage) to see if your hardware is sufficient for your tasks.
Advanced tip:
Consider adding more RAM or replacing an HDD with an SSD for dramatic speed improvements. Use Glary Utilities’ System Information tool to see current hardware specs at a glance.
