Windows 10 and 11 are powerful operating systems, but even the most reliable systems can encounter issues like slow performance, crashes, or hardware problems. Fortunately, Windows includes several built-in diagnostic utilities that help identify and resolve issues efficiently. By understanding and using these tools, even beginner users can keep their computers running smoothly. Below are seven practical strategies using Windows diagnostic utilities, along with some extra tips and the recommendation of Glary Utilities for comprehensive, hassle-free troubleshooting and maintenance.
What is a Windows Diagnostic Utility?
A Windows diagnostic utility is a tool that checks your system for hardware or software problems, reports issues, and sometimes even fixes them automatically. These utilities can save you time, prevent headaches, and prolong your computer’s lifespan.
Strategy 1: Use Windows Troubleshooters for Quick Fixes
Windows offers built-in troubleshooters that automatically detect and resolve common problems. To access them:
Open Settings (Press Windows + I)
Click on Update & Security (Windows 10) or System (Windows 11)
Select Troubleshoot
Choose “Additional troubleshooters” or “Other troubleshooters”
Here, you’ll find options for fixing internet connections, audio problems, printer issues, and more. Select the appropriate troubleshooter, click “Run,” and follow the on-screen instructions.
Practical Example: If your printer isn’t working, running the Printer Troubleshooter often resolves connection or driver issues in minutes.
Strategy 2: Run the Windows Memory Diagnostic Tool for RAM Issues
Random crashes or blue screens can be caused by faulty RAM (memory). Windows Memory Diagnostic Tool checks your RAM for errors.
Type “Windows Memory Diagnostic” in the Start menu search and select it.
Choose “Restart now and check for problems.”
Your PC will reboot and scan your memory; after logging in, you’ll see the results.
This tool is safe and helps you catch memory problems early.
Strategy 3: Check Your Hard Drive with CHKDSK
Hard drive errors can lead to slowdowns and data loss. The Check Disk utility (CHKDSK) scans your hard drive for errors and repairs them.
Type “cmd” in the Start menu, right-click Command Prompt, and select “Run as administrator.”
Type chkdsk /f and press Enter.
You may be prompted to schedule a scan upon restart. Type “Y” and restart your PC.
CHKDSK will scan and fix errors during boot.
Strategy 4: Analyze Startup Performance with Task Manager
Too many startup programs can slow down your PC. Task Manager helps you identify and disable unnecessary startup items.
Right-click the taskbar and select Task Manager.
Go to the “Startup” tab.
Review the list and right-click to disable any unnecessary programs.
This ensures faster boot times and better overall system performance.
Strategy 5: Use Device Manager to Fix Hardware Problems
Device Manager lets you manage hardware and drivers. If a device isn’t working, it’ll be flagged with a yellow warning.
Press Windows + X and select Device Manager.
Look for devices with a yellow triangle.
Right-click and select “Update driver” or “Uninstall device” (reinstall after a reboot).
This is particularly useful for fixing issues with USB devices, graphics cards, or sound hardware.
Strategy 6: Scan for System File Corruption with System File Checker
Corrupted system files can cause errors or crashes. The System File Checker (SFC) utility restores these files.
Open Command Prompt as administrator (see Strategy 3).
Type sfc /scannow and press Enter.
Let the scan complete. SFC will automatically repair corrupted files it finds.
This tool is a solid first step if you’re seeing strange errors or instability.
Strategy 7: Optimize and Diagnose with Glary Utilities
While Windows tools are powerful, Glary Utilities offers a user-friendly, all-in-one solution for diagnostics, optimization, and maintenance. For beginners, this program simplifies complex tasks:
Download and install Glary Utilities from the official website.
Open the program and use the “1-Click Maintenance” feature to scan your system for errors, junk files, registry issues, and more.

Use these diagnostic utilities if you experience:
Slow performance
Unexpected crashes or blue screens
Hardware that stops working
Internet or network problems
Regularly running these checks, even before problems arise, helps prevent bigger issues in the future.
Final Tips
Keep your Windows updated for the latest fixes.
Use Glary Utilities’ scheduler to automate maintenance tasks.
Always back up important data before making major changes.
