Windows 11 is a robust operating system, but like any software, it may encounter errors over time. Whether it’s due to corrupted system files, misconfigured settings, or outdated drivers, these issues can often be resolved with built-in tools and maintenance techniques. Here’s a detailed guide enriched with tricks and tips to fix common Windows 11 errors and keep your system running smoothly.

Step 1: Update Windows

Keeping Windows up to date ensures your system has the latest security patches and bug fixes. Here’s how to check for updates:

  1. Click on the Start Menu and select Settings.
  2. Navigate to Windows Update.
  3. Click Check for updates. If updates are available, download and install them.
  4. Restart your PC after the updates are installed.

Tip: Enable automatic updates to ensure you’re always protected.

Step 2: Run the System File Checker (SFC)

The System File Checker scans and repairs corrupted system files. Follow these steps:

  1. Press Windows + S to open the search bar and type “Command Prompt”.
  2. Right-click on Command Prompt and select Run as administrator.
  3. Type the following command and press Enter: 
    DISM.exe /Online /Cleanup-image /Restorehealth

    This command uses the Deployment Image Servicing and Management tool to repair the system image. It might take several minutes to complete.

  4. Once the operation completes successfully, type the following command and press Enter: 
    sfc /scannow

    This will initiate the System File Checker scan. Wait for the verification process to reach 100%.

  5. After completion, you’ll see a message indicating whether issues were found and fixed. Restart your computer to apply changes.

Tip: If SFC cannot fix all the issues, run the command again after rebooting.

Step 3: Check for Disk Errors

Faulty sectors or disk errors can cause system instability. Use the CHKDSK tool to diagnose and fix these issues:

  1. Open Command Prompt as an administrator.
  2. Type the following command and press Enter: 
    chkdsk /f /r
  3. If prompted to schedule the disk check on the next restart, type Y and press Enter.
  4. Restart your computer, and CHKDSK will run before Windows loads.

Tip: Regularly run CHKDSK on drives with critical data to ensure their health.

Step 4: Optimize Startup Programs

Excessive startup programs can slow down your system and cause conflicts. Manage them effectively:

  1. Open the Task Manager by pressing Ctrl + Shift + Esc.
  2. Go to the Startup tab.
  3. Review the list of programs and disable unnecessary ones by right-clicking and selecting Disable.

Tip: Keep only essential applications enabled, like antivirus software.

Step 5: Update Drivers

Outdated drivers can lead to hardware malfunctions and errors. Ensure all drivers are up to date:

  1. Press Windows + X and select Device Manager.
  2. Expand each category, right-click on a device, and select Update driver.
  3. Choose Search automatically for updated driver software.

Tip: Use reliable third-party driver updater tools for convenience, but ensure they’re from a trusted source.

Step 6: Reset Windows Components

If the above steps fail, resetting critical components can help:

  1. Reset Network Settings:
    • Open Settings, go to Network & Internet, and click Advanced network settings.
    • Choose Network reset and follow the prompts.
  2. Reset Windows Settings:
    • Open Settings, navigate to System > Recovery, and select Reset this PC.
    • Choose to keep your files or remove everything based on your needs.

Tip: Always back up your data before performing a reset.

Additional Tips and Tricks

  1. Run Windows Troubleshooter:
    • Open Settings > System > Troubleshoot.
    • Select the appropriate troubleshooter (e.g., for audio, internet, or updates).
  2. Enable Performance Mode:
    • Open Settings > System > Power & Battery.
    • Under Power mode, select Best performance for faster operation.
  3. Clear Temporary Files:
    • Press Windows + R, type temp, and delete unnecessary files.
    • Repeat with %temp% and prefetch.
  4. Monitor Resource Usage:
    • Use the Task Manager to identify processes consuming excessive resources.
    • End unnecessary tasks to free up system memory.
  5. Use a Reliable Antivirus:
    • Install a trusted antivirus solution to scan and remove malware that might cause errors.
