Windows systems are powerful and versatile, but even well-maintained PCs can slow down or develop performance issues over time. Knowing how to troubleshoot and resolve these slowdowns is essential for both everyday users and IT professionals. Here are the 12 most effective strategies to identify and fix Windows performance problems, with practical steps and real-world examples. Whether you’re a beginner or an advanced user, you’ll find tailored advice to keep your system running smoothly.
1. Identify Resource Hogs Using Task Manager
Beginner Steps:
Press Ctrl + Shift + Esc to open Task Manager.
Look under the ‘Processes’ tab to identify programs using excessive CPU, memory, or disk resources.
Right-click on any suspicious app and select ‘End task’ to stop it.
Advanced Tips:
Switch to the ‘Details’ tab for more granular insights.
Use ‘Resource Monitor’ (found in the ‘Performance’ tab) for deeper diagnostics.
2. Clean Up Junk and Temporary Files
Over time, your system accumulates junk files, temp data, and cache that slow things down.
Beginner Steps:
Open Settings > System > Storage and enable Storage Sense.
Run Disk Cleanup: Search ‘Disk Cleanup’ in Start menu, select your drive, and follow prompts.
Advanced User Solution:
Leverage Glary Utilities for thorough cleanup: Use the ‘Disk Cleaner’ and ‘Tracks Eraser’ modules to safely remove temporary files, browser caches, and other leftovers.
3. Uninstall Unnecessary Programs
Unused or unwanted programs can consume resources in the background.
Beginner Steps:
Go to Control Panel > Programs > Uninstall a program.
Review the list and remove anything you no longer need.
Advanced Tips:
Use Glary Utilities’ ‘Uninstall Manager’ for a more thorough removal, including registry leftovers that Windows’ built-in uninstaller might miss.
4. Disable Startup Programs
Too many startup applications can dramatically slow boot times.
Beginner Steps:
Press Ctrl + Shift + Esc to open Task Manager.
Go to the ‘Startup’ tab and disable any unnecessary entries.
Advanced Tips:
Glary Utilities’ ‘Startup Manager’ provides more detailed information and lets you manage non-Microsoft startup items, including scheduled tasks and services.
5. Scan for Malware and Adware
Malicious software is a common root cause of poor performance.
Beginner Steps:
Run Windows Defender for a full system scan: Settings > Update & Security > Windows Security > Virus & threat protection.
Advanced Solution:
Supplement with tools like Malwarebytes for deeper scans.
Use Glary Utilities’ ‘Malware Remover’ to catch potentially unwanted programs (PUPs) and adware.
6. Update Windows and Device Drivers
Outdated software and drivers can lead to incompatibility and sluggishness.
Beginner Steps:
Check for updates in Settings > Update & Security > Windows Update.
Advanced Solution:
Update device drivers from Device Manager or by visiting the manufacturer’s website.
Use Glary Utilities’ ‘Software Update’ tool to identify outdated programs.
7. Defragment or Optimize Your Hard Drive
Fragmented data can slow down traditional HDDs (not necessary for SSDs).
Beginner Steps:
Type ‘Defragment and Optimize Drives’ in the Start menu, select your drive, and click ‘Optimize.’
Advanced Tips:
Set up an optimization schedule for regular maintenance.
Use Glary Utilities’ ‘Disk Defrag’ for more customization and optimization features.
8. Check for Disk Errors
Bad sectors and file system errors can degrade performance.
Beginner Steps:
Open ‘This PC,’ right-click your drive, go to ‘Properties’ > ‘Tools,’ and click ‘Check’ under ‘Error checking.’
Advanced Tips:
Use Command Prompt as an administrator and run chkdsk /f /r.
9. Tweak Visual Effects
Windows’ visual effects can use valuable system resources.
Beginner Steps:
Right-click ‘This PC’ > ‘Properties’ > ‘Advanced system settings.’
Under ‘Performance,’ click ‘Settings’ and select ‘Adjust for best performance.’
Advanced Solution:
Customize only certain visual effects such as smooth edges of screen fonts for a balance between appearance and speed.
10. Manage Virtual Memory (Paging File)
Improper virtual memory settings can lead to slowdowns or errors.
Beginner Steps:
Go to System Properties > Advanced > Performance > Settings > Advanced > Virtual memory.
Select ‘Automatically manage paging file size.’
Advanced Tips:
Manually set custom sizes for the paging file if you know your RAM requirements.
11. Analyze and Manage Windows Services
Some services are unnecessary and may consume resources.
Beginner Steps:
Be cautious; beginners should leave services alone unless directed.
Advanced Solution:
Open ‘services.msc’ and disable or set to manual any non-essential services (research each before changing).
Glary Utilities’ ‘Startup Manager’ also lists and explains services to help make safe decisions.
12. Restore System Health with System File Checker
Corrupted files can cause instability and slow performance.
Beginner Steps:
Open Command Prompt as administrator and type sfc /scannow.
Let Windows scan and repair system files automatically.
Advanced Tips:
If problems persist, run DISM commands: DISM /Online /Cleanup-Image /RestoreHealth.
