Windows errors can be a major interruption to productivity and peace of mind. Whether you’re a beginner or an advanced user, knowing how to fix these errors efficiently is crucial. This guide presents twelve actionable strategies—ranging from basic to advanced—designed to help you clean up and repair your Windows system, restore stability, and prevent future issues. Drawing on professional experience, these methods combine manual troubleshooting with powerful tools like Glary Utilities for comprehensive system maintenance.
Beginner Strategies: Easy Fixes for Common Windows Errors
1. Run Windows Troubleshooters
Windows includes troubleshooters for common problems like network issues, sound problems, and system updates. To use them, open Settings, navigate to Update & Security, then Troubleshoot, and select the relevant troubleshooter. These automated tools can quickly resolve many basic errors and are a great first step for beginners.
2. Restart Your Computer
It sounds simple, but many Windows errors are temporary glitches that can be cleared with a restart. Restarting flushes memory, resets processes, and can resolve issues such as application freezes, slowdowns, or minor hardware conflicts.
3. Use Disk Cleanup to Remove Temporary Files
Over time, temporary files and cache can cause errors or slow down your system. Use Windows’ built-in Disk Cleanup tool: type “Disk Cleanup” in the Start menu, select your drive, and delete unnecessary files. For a more complete cleanup, Glary Utilities offers deeper scanning to find and remove even more junk files.
4. Update Windows and Device Drivers
Outdated system files and drivers are a frequent cause of errors. Check for Windows Updates via Settings > Update & Security > Windows Update. For drivers, visit Device Manager, right-click any problematic device, and select Update driver. Glary Utilities also includes a driver manager for streamlined updates.

5. Scan for Malware and Viruses
Malware often causes unexplained Windows errors. Run a full system scan with Windows Defender or your preferred antivirus. Glary Utilities also includes a malware remover to provide extra protection and supplement your main antivirus.
6. Use System File Checker (SFC) and DISM Tools
Corrupted system files are a classic cause of Windows errors. Open Command Prompt as administrator and run “sfc /scannow”. This repairs corrupt files automatically. If further issues persist, run “DISM /Online /Cleanup-Image /RestoreHealth” to fix deeper Windows image problems.
7. Clean and Repair the Windows Registry
Registry errors can impair performance and cause various glitches. Glary Utilities offers a safe Registry Cleaner that scans for invalid entries, missing file references, and other errors—removing them safely to prevent future issues. Unlike manual registry editing, this tool minimizes the risk of accidental damage.
8. Uninstall Unnecessary Programs and Plugins
Old or unused software can lead to conflicts and errors. Go to Control Panel > Programs and Features to uninstall what you don’t need. For more thorough removal, Glary Utilities’ Uninstall Manager detects leftover files and registry entries, ensuring complete cleanup.

9. Restore Your System with System Restore
When errors appear after a recent software install or update, use System Restore to revert your system to an earlier state. Search for “System Restore” in the Start menu, choose a restore point, and follow the prompts. This is a powerful way to undo problematic changes without affecting your personal files.
10. Check Disk for Errors (CHKDSK)
Hard drive errors can lead to data corruption and system instability. Open Command Prompt as administrator and run “chkdsk /f”. This scans and repairs disk errors on reboot. Glary Utilities also provides a Disk Repair tool for user-friendly disk error detection and correction.
11. Manage Startup Programs
Too many startup programs bog down your system and can cause loading errors. Use Task Manager (Ctrl+Shift+Esc) under the Startup tab to disable unnecessary entries. Glary Utilities’ Startup Manager gives more detailed control, allowing you to identify and delay non-essential startup processes for faster boots and fewer conflicts.
12. Perform a Clean Boot
If persistent errors resist all other fixes, perform a clean boot to start Windows with only essential services and drivers. In System Configuration (msconfig), select “Selective startup” and disable non-Microsoft services. This isolates problematic software and helps identify the root cause of elusive errors.
Which Strategy Should You Use First?
Beginners should start with the simplest methods: troubleshooting tools, restarts, and disk cleanup. Intermediate users can safely use SFC, uninstallers, and registry cleaners. Advanced users may need to dive into System Restore, CHKDSK, and clean boot procedures.
