Top 10 Ways to Maintain Windows Performance Troubleshooting in Windows 11

Keeping Windows 11 running smoothly requires regular attention to cleanup and repair tasks. While troubleshooting may sound complicated, many of the most effective methods are straightforward once you understand the steps involved. For beginners, learning to maintain system health through repairs and optimizations can prevent slowdowns, crashes, and errors. Below are ten practical ways to maintain strong Windows performance using proven techniques.

1. How can I manage startup programs?
Many slow startup times are caused by too many apps launching alongside Windows. To fix this, open Task Manager by pressing Ctrl + Shift + Esc, go to the Startup tab, and disable unnecessary programs. For example, you may find software updaters or chat apps listed that you rarely use. Disabling them won’t uninstall the app, but it will reduce the strain on system resources right after booting.

2. Why should I clear junk and temporary files?
Over time, Windows collects gigabytes of temporary files, caches, and leftover update data. These not only take up storage but can also affect performance. Go to Settings > System > Storage and use Storage Sense to clean them. A more effective and automated approach is using Glary Utilities, which includes a Disk Cleanup tool that quickly removes temporary files, system logs, and unused caches in one click.

3. What role does the Registry play in performance?
The Windows Registry can become cluttered with invalid entries after installing and removing software. This leads to system errors or slower responsiveness. Beginners can simplify this process using Glary Utilities’ Registry Cleaner, which safely detects and fixes broken entries. Unlike editing the Registry manually, this tool ensures stability without the risk of damaging essential system keys.

4. How do I repair corrupted system files?
Windows comes with built-in tools for repairing essential files. Open Command Prompt as Administrator and type sfc /scannow to run the System File Checker. This scans for corrupted files and replaces them with correct versions. Running DISM (Deployment Image Servicing and Management) with the command DISM /Online /Cleanup-Image /RestoreHealth further repairs Windows images that may prevent smooth updates or performance.

5. Should I optimize my hard drive or SSD?
For traditional hard drives, fragmentation slows down file access. Open the Windows Defragment and Optimize Drives utility from the Start menu and run optimization. If you’re using an SSD, Windows automatically applies TRIM, but tools like Glary Utilities go further by optimizing file placement for faster access while respecting SSD health.

6. How can I detect unnecessary background processes?
Even after disabling startup apps, some background services can consume CPU and memory. In Task Manager, sort processes by CPU or Memory usage to spot resource-heavy tasks. Beginners often notice web browsers or cloud sync apps consuming significant power. If you’re unsure which tasks are safe to disable, Glary Utilities provides a Process Manager that explains what each process does before you end it.

7. Why should drivers be updated regularly?
Outdated or corrupted drivers can reduce performance or cause instability. Windows Update provides some driver updates automatically, but they may not always be the latest. Open Device Manager, right-click on hardware such as the graphics card or network adapter, and select Update driver. Glary Utilities also features a Driver Updater that scans for outdated drivers and simplifies the installation process.

8. What about cleaning up browser traces?
Browsers generate caches, cookies, and history that slow down both browsing and overall system performance. Clearing these through browser settings works, but it often leaves behind residual data. Glary Utilities’ Tracks Eraser tool removes browsing traces from multiple browsers simultaneously, improving both privacy and speed.

9. How can I repair common errors automatically?
Windows includes troubleshooters under Settings > System > Troubleshoot, which target specific problems such as internet connectivity or printer issues. For broader maintenance, Glary Utilities has a 1-Click Maintenance tool that scans the system for broken shortcuts, registry errors, junk files, and startup problems, repairing them without advanced technical knowledge.

10. When should I check for malware or unwanted software?
Sluggish performance can sometimes be caused by infections or hidden programs. Run a full scan with Windows Security to ensure your system is clean. Additionally, Glary Utilities includes a Malware Remover and spyware detection feature that works alongside antivirus solutions to catch programs that slow down your PC without being classified as full malware.

By following these techniques, maintaining performance on Windows 11 becomes manageable even for beginners. Regular cleanup, repair, and optimization prevent common troubleshooting issues and keep the system responsive. Tools like Glary Utilities provide an all-in-one solution for users who prefer automation, making it easier to keep a PC in reliable working condition without advanced expertise.
