Quick Note: Basic Checks Before Troubleshooting

Before diving into specific fixes, make sure to do these quick checks:

  • Restart your computer: A simple restart can clear temporary glitches causing errors.

  • Ensure your device is connected to the internet: Some errors occur due to connectivity issues.

How to Fix Common Windows 10 Errors: Step-by-Step

1. Windows Update Errors

Why it matters: Windows updates keep your system secure and optimized. Errors during updates can leave your PC vulnerable or unstable.

  1. Run the Windows Update Troubleshooter:
    • Go to Settings > Update & Security > Troubleshoot.
    • Select Windows Update and click Run the troubleshooter.
    • Follow the on-screen instructions to fix any detected issues.
  2. Clear the Software Distribution Folder:

    This folder stores update files that might be corrupted. Deleting it forces Windows to download fresh files.

    • Open Command Prompt as Administrator by typing cmd in the search bar, right-clicking it, and selecting Run as administrator.
    • Type these commands one by one, pressing Enter after each:
      • net stop wuauserv
net stop bits
    • Navigate to C:WindowsSoftwareDistribution in File Explorer.
    • Delete all files and folders inside the SoftwareDistribution folder.
    • Return to Command Prompt and type:
      • net start wuauserv
net start bits
    • Restart your PC and try updating again.
  3. Manually Download and Install Updates:

    If automatic updates fail, you can manually download updates from the Microsoft Update Catalog.

    Search for the update code (e.g., KB5005565), download the correct version, and install it manually.

2. Blue Screen of Death (BSOD) Errors

Why it matters: BSOD indicates a serious system error. Fixing it prevents data loss and system crashes.

  1. Note the Error Code:

    When the BSOD appears, write down the error code (e.g., IRQL_NOT_LESS_OR_EQUAL or 0x0000007E). This helps identify the cause.

  2. Update Drivers:

    Outdated or faulty drivers often cause BSODs.

    • Open Device Manager by right-clicking the Start button and selecting it.
    • Look for any device with a yellow warning icon.
    • Right-click the device and select Update driver.
    • Choose Search automatically for updated driver software.
  3. Run System File Checker (SFC):

    This tool scans and repairs corrupted system files.

    • Open Command Prompt as Administrator.
    • Type sfc /scannow and press Enter.
    • Wait for the scan to complete and follow any instructions.
  4. Check for Hardware Issues:

    Faulty RAM or hard drives can cause BSODs.

    • Run Windows Memory Diagnostic by typing it in the search bar and choosing Restart now and check for problems.
    • Check your hard drive health using tools like CHKDSK:
      • chkdsk /f /r
    • Run this command in Command Prompt and restart your PC when prompted.

3. Application Crashes or Won’t Open

Why it matters: Apps not working can disrupt your tasks. Fixing them restores productivity.

  1. Restart the App:

    Close the app completely and reopen it. Sometimes temporary glitches cause crashes.

  2. Run as Administrator:

    Some apps need elevated permissions.

    • Right-click the app icon and select Run as administrator.
  3. Update the App:

    Outdated apps may be incompatible with Windows 10 updates.

    • Check the app’s official website or Microsoft Store for updates.
  4. Reinstall the App:

    If the app is still crashing, uninstall and reinstall it.

    • Go to Settings > Apps > Apps & features.
    • Find the app, click it, then select Uninstall.
    • Download and install the latest version again.
  5. Check for Compatibility Mode:

    If the app was designed for an older version of Windows, try running it in compatibility mode.

    • Right-click the app icon and select Properties.
    • Go to the Compatibility tab.
    • Check Run this program in compatibility mode for: and select a previous Windows version.
    • Click Apply and then OK.

4. Network Connection Issues

Why it matters: Internet connectivity is essential for many tasks. Fixing network errors helps you stay connected.

  1. Restart Your Router and PC:

    Power cycling your router and computer resolves many network glitches.

  2. Run Network Troubleshooter:
    • Go to Settings > Network & Internet > Status.

    This restores all network components to default, fixing configuration issues.

    • Click Reset now and restart your PC.
  4. Update Network Drivers:
    • Open Device Manager.
    • Find your network adapter under Network adapters.
    • Right-click it and select Update driver.
    • Choose Search automatically for updated driver software.
