Windows 10 and 11 are powerful operating systems, but over time, even the most robust systems can slow down or develop performance issues. From sluggish boot times to frequent application crashes, performance hiccups can be frustrating. This professional guide will walk you through step-by-step troubleshooting and repair techniques, offering both beginner-friendly instructions and advanced tips. The focus is on clean up and repair strategies, with actionable examples and the recommendation of Glary Utilities to streamline your tasks.
Why Does Windows Slow Down?
Before diving into solutions, it’s important to understand why Windows performance issues occur. Common culprits include:
– Accumulated junk files and cache
– Fragmented or failing hard drives
– Too many startup programs
– Outdated or corrupted drivers
– Malware or unwanted software
– Registry errors and misconfigurations
Addressing these issues systematically will help restore—and maintain—your PC’s speed.
For Beginners: Simple Clean Up & Repair Steps
Is Your PC Running Slow? Start Here
1. Remove Unnecessary Startup Programs
Many applications launch automatically when Windows starts, slowing down your boot time.
– Right-click the taskbar and select Task Manager.
– Go to the Startup tab.
– Disable non-essential programs (right-click > Disable), leaving essential system items enabled.
2. Uninstall Unused Applications
Unused software takes up space and can slow performance.
– Open Settings > Apps > Installed apps (Windows 11) or Apps & features (Windows 10).
– Review the list and uninstall what you no longer use.
3. Clean Up Temporary Files and System Junk
Temporary files, browser cache, and leftovers from updates can accumulate quickly.
– Press Windows+R, type cleanmgr, and press Enter. Select your drive, tick the boxes for files to delete, and click OK.
Professional Tip: Glary Utilities can automate junk file removal, clear browser histories, and safely clean up system clutter with a single click. This saves time and ensures nothing important is deleted by mistake.
4. Perform a Disk Check
File system errors can affect performance.
– Open Command Prompt as administrator.
– Type chkdsk /f and press Enter. If prompted to schedule a scan on next boot, type Y and restart your PC.
5. Run Windows Update
Updates can fix bugs and improve performance.
– Go to Settings > Update & Security > Windows Update.
– Click Check for updates and install any available.
For Advanced Users: In-Depth Repair Techniques
Want to Go Deeper? Try These Advanced Steps
1. Check Resource Usage with Task Manager
– Press Ctrl+Shift+Esc to launch Task Manager.
– Review the Processes tab for apps using excessive CPU, Memory, or Disk.
If you spot a process repeatedly spiking resources (like an updater gone rogue), right-click and select End Task or research the process name to see if it’s safe to remove.
2. Use System File Checker and DISM
Corrupted system files can cause mysterious slowdowns or errors.
– Open Command Prompt as administrator.
– Run:
sfc /scannow
– After completion, run:
DISM /Online /Cleanup-Image /RestoreHealth
3. Advanced Registry Cleaning
While Windows manages the registry, over time, unused or broken entries can linger—potentially causing issues.
– Glary Utilities includes a safe, automatic registry cleaner.
Open Glary Utilities, go to the Registry Repair module, and let it scan. Review findings and apply fixes. (Always back up before making changes.)
4. Defragment and Optimize Drives
Traditional hard drives (not SSDs) benefit from defragmentation.
– Open Glary Utilities, select the Disk Defrag module, and analyze/defrag your drive for optimized access speeds.
5. Investigate Malware or Adware
Malware can dramatically impact performance.
– Run a reputable antivirus scan.
– Glary Utilities offers a built-in Malware Remover tool for quick checks and clean-ups of common threats.
