How to Fix PFN_LIST_CORRUPT Error on Windows

Cortana is your personal digital assistant fully integrated into Windows 10 designed to help you make your life easier. The more you use it, the more Cortana can learn about you, and the experience becomes more personalized and accurate. It can perform a variety of tasks, and it's full of handy tricks, but perhaps one of the best features is the advanced speech recognition that enables Cortana to understand the context of a natural voice conversation. On Windows 10, and across platforms with the Cortana app on iPhone and Android, the assistant can understand virtually any voice command and perform tasks. For example, by just speaking you can find facts, create reminders and manage your calendar, launch applications, change settings, and a lot more. Now, if you're looking for an official list of all the voice commands Cortana supports, you'll never find it because it doesn't exist. Cortana can understand natural language and context, there's no particular set of commands to make things happen. In a sort of way, you are speaking to Cortana as you would to any other person.

Invoking Cortana

Before using voice commands, it's important to know the ways in which you can invoke Cortana using natural language:

• You can click the microphone icon in the taskbar next to the Start menu.
• You can use the Shift + ⊞ Windows + C keyboard shortcut to open Cortana in listening mode.
• You can use the Hey Cortana feature, which lets you invoke the assistant by simply saying Hey Cortana followed by the command. For example, Hey Cortana: How's the weather?.
• On Windows 10 Mobile devices, you can press and hold the search button to open Cortana in listening mode.

Comprehensive list of Cortana voice commands

The following list of commands are examples you can use to learn how to control Cortana with voice commands. Keep in mind that there isn't a specific way to speak the commands. For example, Hey Cortana: Let me listen to some tunes is the same as asking for a more systematic command like Hey Cortana: Play music.

Error Code 47 – What is it?

It is a device driver error that users encounter when they use Windows 2000 operating system and its later versions.

The error occurs when the connected peripheral device, upon removal using the ‘Safe Removal Hardware’ program, hangs up a problem within the process. The error prompt you then see is referred to within the operating system as error code 47.

It usually pops up on your computer screen with the following message:

Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47)

Solution

Error Causes

Since Windows 10 introduced the concept of notifications, almost any application installed on your computer sends you one. However, there are times when too many notifications can be quite annoying. Although some of them are important, most of them are not and are only getting in the way of your tasks. So if you don’t like to be flooded with tons of notifications on your Windows 10 computer, say no more as this post will help you out in disabling notifications for any apps installed. And now with the new feature in Windows 10 called Focus Assist, you will be able to manage the level of notifications that you receive. This new feature also allows you to disable all notifications except for the ones from important or priority apps. You will just have to maintain a list of priority applications or you could also disable all the notifications except for the important ones like alarms. In addition, you could also set up some automatic rules such as the Focus Assist timings which means that you can make Focus Assist enabled for a certain period of time during the day or when you are duplicating your display or playing a game and whatnot. So if there is an application that keeps on spamming you with notifications, you can just disable the notifications for that application.

To get started on disabling notifications, refer to the steps given below.

• Step 1: Go to Settings > System.
• Step 2: From there, open Notifications and actions and then scroll down to the “Get notifications from these apps” section.
• Step 3: After that, look for the application that you want to disable notifications for and click on the toggle button that corresponds to disabling notifications for that application. You could also click open to explore additional settings for that particular application.

Note: You can disable notifications or just the notification banners, your choice. Aside from that, you can also control the notification sound as well as its behavior when the computer screen is locked. What’s more, is that you can also adjust the number of notifications displayed in the Action Center or select the priority applications. As stated earlier, Windows 10 gives you control that allows you to customize every nook and cranny of the notification on your Windows 10 computer. Apart from applications, there are also other notifications-related settings that you can control including disabling notifications about tips, tricks, and suggestions as well as summary notifications from Windows Defender that you get every time you use or scan your computer.

One of the most common Blue Screen of Death errors you can encounter on your Windows 10 computer is the Tcpip.sys Blue Screen error. The Tcpip.sys file is a driver file that is associated with the Transmission Control Protocol over Internet Protocol. When you see this kind of BSOD error, you may see any of the following error descriptions:

• IRQL_NOT_LESS_EQUAL
• KMODE_EXCEPTION_NOT_HANDLED
• PAGE_FAULT_IN_NONPAGED_AREA

Whichever error description you got, you need to do use the following instructions below as a reference to obliterate the Tcpip.sys Blue Screen error.

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 Tcpip.sys Blue Screen error. 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 – Try resetting TCP/IP

In case you didn’t notice, the Tcpip.sys file is associated with the TCP/IP protocols in your computer system which is why resetting TCP/IP can help in resolving the Tcpip.sys Blue Screen of Death error especially when the TCP/IP has been modified.

• First, you need to type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option to open Command Prompt.
• After that, type the following command in the elevated cmd window and hit Enter:

netsh int ip reset

• Now reboot your computer after the command has been executed and check if it helped to fix the Blue Screen error.

Option 3 – Try to rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 5 – Try to disable both the Antivirus program and Firewall temporarily

There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects which is why you have to disable these programs temporarily as it might be the reason why you’ve encountered the error when trying to browse the internet.

There are instances when the Windows 10 installation needs interaction before it reaches the file process. And so if you suddenly encounter the Windows Update Installation Failure 0x80240020 error under the Windows Update History, then you need to get it fixed. When you encounter this kind of Windows Update Error, you will see an error message that says, “The operation did not complete because there is no logged-on interactive user”. This error also indicates the “WU_E_NO_INTERACTIVE_USER” code. To resolve this issue, in this post we’ll walk you through a couple of steps but before you get started, know that you don’t have to run any troubleshooter or delete any file just to fix this error since all you have to do is enable one option that can automatically login with your account and complete the installation for you. With that said, just make sure to only try running Windows Update once you’re told to do so. There are two ways you can enable the option that could resolve the Windows Update Installation Failure 0x80240020 error. One is via Settings while the second one is via Registry Editor.

Option 1 – via Settings

Step 1: Go to Settings > Accounts > Sign-in Options. Step 2: From there, toggle on the “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart” option. Step 3: After that, it will make sure that the interaction part is removed from the Windows Update process. Note: If your device is joined in a domain or if some work or email policies are applied to your device by your company or organization, then you wouldn’t be able to see this option in Settings and that’s where the Registry Editor comes in. Just make sure that you’re logged in as an administrator and that you create a System Restore Point first since registry hacks are sensitive and could highly impact how your computer behaves or functions. Once you have that covered, follow the steps below.

Option 2 – via Registry Editor

Step 1: In the Start search, type “Regedit” and hit Enter to open the Registry Editor. Step 2: Navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade

Note: If the above-given registry key does not exist, you can simply create it. All you have to do is right-click on the WindowsUpdate key and then select the New Key option and type “OSUpgrade” as its name. Afterward, create a new DWORD (32-bit) Value and name it “AllowOSUpgrade” and set its value to 0x00000001. Step 3: Restart your computer and check if the error is now fixed. And then try to update your Windows 10 computer again and while you’re at it, make sure that you’re around your computer to interact with the prompts needed to complete the installation process.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
