How to Fix PFN_LIST_CORRUPT Error on Windows
If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:
  • Tap the Win + I keys to open the Settings panel.
  • Then go to Update & Security > Troubleshoot.
  • From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

  • On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
  • Next, click on Disk Management on the left side panel.
  • From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.
You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.
  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
  • Wait for the process to be completed and then restart your computer.

Option 4 – Update the Device drivers

Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.
  • Tap the Win + R keys to launch Run.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.
  • Tap the Ctrl + Shift + Esc keys to open the Task Manager.
  • Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
  • Then go to the Startup tab and select Microsoft OneDrive and then click Disable.

Configuring Groove Music Equalizer in Windows
In case you don’t know, Groove Music is due to retire its OneDrive streaming service this month. Despite that being the case, there is actually a workaround you can try to still continue enjoying music streaming. The app also allows you to play your own local files and if required, you can also modify or tailor the experience with new features – for instance, Groove Music brings an Equalizer to the settings of the app. As the name suggests, the equalizer allows you to tweak frequency responses to your liking. On top of being able to tweak individual bands, the equalizer supports few pre-set settings to enable quick changes. This post will guide you on the process of accessing and using the equalizer in the Groove Music app. To get started, refer to the instructions provided below. Step 1: You need to make sure that you are running the latest version of the Groove Music app or version 10.18011.1211.0 or higher in order to use the equalizer in Groove Music. If needed, you can check the version number from Windows Store. Step 2: Open Windows Store and then click on the ellipses icon and select the Downloads and Updates option. Step 3: Next, search for Groove Music and check its version number. Step 4: Now that you’ve verified the version number of Groove Music, you need to open the equalizer setting. It is enabled by default and to access it, click on the gear icon for Settings and select equalizer under the Playback settings. Step 5: After that, the Equalizer window will pop up. It is where you can configure the equalizer settings using the drop-down menu. Here are the following presets you can choose from:
  • Flat
  • Treble Boost
  • Bass Boost
  • Headphones
  • Laptop
  • Portable speakers
  • Home Stereo
  • TV
  • Car
  • Custom
Step 6: Drag the dots upwards or downwards to set your own preferences, as needed. Note: The only downside to this setting is that there is no shortcut available for quick access as you have to navigate through the Settings section manually to access it and change the preset configurations. In addition, the Groove Music app also works on the mobile version of Windows 10.

How to Fix Windows 10 Error Code 0xc004fc03

Error Code 0xc004fc03 – What is it?

Error code 0xc004fc03 occurs when Windows users fail to activate their Windows operating system due to a networking problem. The error code’s common symptoms include the following:

  • Inability to activate Windows 10 operating system
  • Message box with error code 0xc004fc03

Solution

Restoro box imageError Causes

Error code 0xc004fc03 in Windows 10 usually occurs due to issues related to a Windows user’s network. Your computer may be having problems connecting to the Internet or your firewall may be blocking or interrupting your device’s ability to activate Windows 10. In some cases, users may simply need to wait a day or two to reattempt to activate their system using a valid product key, as there may be an issue with the Windows activation servers.  Failure to promptly fix this error code might result in other Windows 10 error messages, such as error code 0xc004f034.

Further Information and Manual Repair

To rectify the error code, Windows 10 users will need to perform manual repair procedures that fix the underlying problems causing error code 0xc004fc03. These procedures may include reconnecting to one’s network, checking your firewall settings, or activating your Windows operating system via phone. The manual repair methods are simple and do not require technical knowledge of the Windows operating system. If your attempts at manually repairing this error code fail, however, you may need to try a few other procedures.

Method One: Verify Internet Connection

To check your Internet connection, you’ll need to access the Network & Internet tab in Windows 10. Follow the instructions below to access this tab and fix Internet connectivity issues if they are preventing you from activating Windows on your machine.

  • Step one: Click the Start button and select Settings
  • Step two: Select Network & Internet
  • Step three: Click the Status section of the Network & Internet tab

If your status shows that you are not connected to a network, you will need to fix your connection. Simply use the Network Troubleshooter to troubleshoot your connection. You will be able to activate your copy of Windows once your connectivity issues are resolved.

If, however, the problem persists and error code 0xc004fc03 occurs during the activation process, this simply means that the existence of the error code is not due to connectivity or networking problems. In such a case, move to the next manual repair method listed below and follow the exact instructions given.

Method Two: Check Firewall Settings

Windows Firewall protects your PC from hackers, worms, and other malicious programs. However, in some cases, it may result in error codes like error code 0xc004fc03. If your firewall is interfering with the Windows 10 activation, you’ll be able to rectify the problem by simply adjusting your settings. Follow the steps below to check – and adjust if necessary – your Windows Firewall settings.

  • Step one: Click search bar and type firewall
  • Step two: Select Windows Firewall
  • Step three: Select Turn Windows Firewall on or off

In some cases, Windows users may not be able to adjust settings within the Windows Firewall tab, as your firewall settings may be controlled by a third party antivirus software. If this is the case, open the antivirus software and turn off the firewall if the software does not prevent you from making such changes to its settings.

Note, however, that you will need to readjust the settings as soon as you activate your version of Windows 10. This is due to the fact that turning off your firewall settings permanently may lead to exposure to worms and other malicious programs.

Method Three: Activate Windows by Phone

Activation of Windows via phone is another option for individuals experiencing error code 0xc004fc03. The activate by phone option in the Update & Security tab will be available once you fail to activate Windows 10. To complete this manual repair method, follow the steps below.

  • Step one: Select Settings
  • Step two: Click Update & security
  • Step three: Select Activate by phone
  • Step four: Follow the instructions provided thereafter.

This is one of the most effective ways to fix error code 0xc004fc03. If the issue persists, however, you can proceed to the last resort.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

Option 3 – Try disabling UAC

The User Account Control or UAC settings might be the one that’s responsible for Error 740 which is why you have to disable the User Account Control and then verify if it’s the one that triggers the error or not. To do that, simply search for “Change user account control settings” in the Taskbar search box and then drag the blue bar down to the bottom and click the OK button to save the change made.

Option 4 – Select the Elevate without prompting option in the Group Policy Editor

  • Then type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
  • Next, navigate to the following path:
Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options
  • From there, go to the Security Options folder where you can find a policy named “User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode”. Double click on it to open its options.

Tips and tricks for longer SSD life
Today most users have an SSD drive, times have changed and SSD has become your typical computer equipment. A lot of time has passed from the first SSD hard drives up to today and technology has evolved and improved but still, there are some cool tricks and tips to speed up and extend the lifespan of your SSD hard drive. That being said let us dive right into what I would like to call the essentials of having an SSD hard drive.
  1. Keep your SSD firmware up to date.

    This one really is a no-brainer, keeping your firmware updated at all times will ensure longer life and SSD stability. The trick here is that each SSD manufacturer has its own ways of updating firmware so this is not something universal, you will have to go to the official website of your SSD manufacturer and get firmware updates and instructions from them directly.
  2. Enable ACHI.

    Advanced controller host interface or short ACHI is a feature that will ensure that your Windows will support all of the features that come with running SSD on your computer. It controls the TRIM feature which is crucial in helping Windows itself in its garbage collection on your hard drive. In order to enable ACHI, you will have to do it from your BIOS and it would be very good if the feature is enabled before Windows itself is installed so it can take full advantage of it.
  3. Enable TRIM.

    TRIM feature is vital in extending your SSD lifespan and it should be enabled by default in Windows but you can never be too cautious and double-check and enable if needed. To make sure it is enabled, open your command prompt and type in: fsutil behavior set disabledeletenotify 0
  4. Make sure your system restore is enabled.

    In the first SSD days, system restore was really a feature that you wanted to be disabled in order to prevent and extend the life span of your SSD drive, but we came a long way from there and today there is no reason to keep this feature turned off since it can be helping many ways with both your system and SSD.
  5. Disable Indexing in Windows.

    A large portion of the speed of your SSD drive is used for indexing files in Windows. Of course, the indexing feature is great if you store everything on your SSD drive but if by any chance you have another drive for your backup, pictures, music, etc. it would be highly beneficial for you to turn it off on your SSD. To turn indexing off click on your start menu, click on the computer. Right-click on your SSD and then click on properties. De-select box that says: Allow files to have contents indexed in addition to file properties and click OK. Once you do this the operating system will apply this to all the files and folders on the drive. If you see a dialog telling you that it couldn’t remove a file from the index, click Ignore All.
  6. Keep Windows defrag ON.

    This also was the option in early SSD days which was better to be OFF, but as said before since technology has been making progress and Windows has been improved and made aware of SSD drives, defrag has evolved as well, and now it is more of optimization tool then defragmenter which was once.
  7. Disable Prefetch and Superfetch.

    Windows is placing information in both physical and virtual memory for applications that you are not currently using but they are used often in order to speed their response time. If you are running low on space or having struggles with virtual memory it would be best to turn them both off. Go to registry manager and find: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters, there you have 2 values: EnablePrefetcher and EnableSuperfetch, set both values to 0.
  8. Disable Search and Superfetch services.

    Disabling Superfetch in the registry is not all work, Press WINDOWS + R to bring run dialog, type in it services.msc, Find both Search and Superfetch and disable them.
  9. Configure Write Caching.

    Write caching can be enabled and disabled in the device manager by expanding disk drives, right-clicking on SSD, then click properties, select the policies tab. In the tab, there is the option to Enable write caching on the device. Now trick in this is that you will need to try and benchmark your SSD with both options turned ON and OFF since different manufacturers have different performances with this option being ON or OFF.
  10. Disable CleanPageFileAtShutdown and LargeSystemCache.

    Page file and a large cache of page files are not something that we longer need, since SSD writes with great speed in its flash memory both of these options can be disabled and you will both speed up shut down the process of your system and save some SSD life since page files will not be written. Find both options in the registry under the key: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management set both to 0
  11. Set high performance in Power options.

    This option in power management will prevent your SSD from constantly shutting down and bringing it up increasing speed without sacrificing its life span.
These are tips and tricks for having great and longer life as well as speed for your SSD drive. We hope that you have found them useful and that you will come again to check new articles published daily for easier IT life.

  6. Choose startup applications

    If you have many applications starting up with your Windows and many of them running in the background you will experience performance issues. Each application that runs in the background is taking RAM and CPU time for themselves which could be free and used for the program that you need.
