5 Best Practices to Avoid Hpqkbfiltr.sys file-Related Issues

The key requirement to avoid having hpqkbfiltr.sys file-related issues is to simply have a clean and optimized computer. To achieve that, here are some best practices to consider:

1. Run a Regular Malware Scan.

Windows 10/11 devices come with built-in antivirus software called Windows Defender. This software is enabled upon first use of a new Windows computer. However, if another antivirus tool is installed, it will automatically deactivate itself.

To run a basic scan with Windows Defender, follow these steps:

  1. Open the Start menu.
  2. Select All Apps.
  3. Go to Windows System and select Windows Defender to bring up the software’s interface.
  4. Decide if you want to run a Full Scan or Quick Scan. A full scan can take quite some time to finish, whereas a quick scan can only take a few minutes as it will only scan the locations that are prone to have bugs.

2. Clean Your Hard Drive.

Here are some easy steps on how to clean your hard drive using the Windows Clean Disk tool:

  1. Open the Start menu.
  2. Go to Programs > Accessories > System Tools.
  3. Select Disk Cleanup.
  4. Under the Drives section, choose which drive you like to run a cleanup.
  5. Choose the files you want to erase.
  6. Hit OK.
  7. Click Delete Files.

If you are unsatisfied with only using the Windows Clean Disk tool that is pre-installed by Microsoft, you can also use a third-party cleaning tool to further scan, clean, and optimize your computer.

3. Uninstall Unnecessary Programs.

To uninstall any unnecessary program in Windows 10/11, follow these steps:

  1. Open the Start menu.
  2. Navigate to Settings > System.
  3. Go to Apps & features.
  4. In the right section of your screen, you will see a list of all installed apps. Select an app that you want to uninstall. Click on it.
  5. You should see an Uninstall button below the name of the app. Click on it to remove the app.
  6. When prompted, click the Uninstall button again to confirm.

4. Check for Autostart Programs Using Run.

If you notice that your computer’s startup speed is slow, you might want to change your Startup settings. Make sure you keep unnecessary programs from launching at startup, including HP Quick Launch Buttons.

To remove HP Quick Launch Buttons from the list of programs that launch at startup, here’s what you should do:

  1. Open Run. Do this by using the Windows + R keys.
  2. In the text field, input C:\ProgramData\Microsoft\Windows\StartMenu\Programs\Startup and hit Enter.
  3. Right-click on HP Quick Launch Buttons.
  4. Select Delete.

5. Enable Automatic Windows Updates.

By default, Windows 10/11 will automatically install any updates that contain fixes to common bugs and problems like the NETIO.SYS blue screen errors. But if it does not, just follow the steps below:

  1. In the search bar, input Windows Update Settings and hit Enter.
  2. Select Windows Update Settings from the search results.
  3. Navigate to Windows Update > Advanced Options.
  4. Make sure that Automatic (recommended) is selected in the drop-down menu.
