Fixing Tcpip.sys Blue Screen Error in Windows

As of late, a number of users reported experiencing a problem where their Windows 10 computers get stuck on Airplane mode for some unknown reason. According to the affected users, they were unable to turn off the Airplane mode which means that their computers are also not able to connect to the internet. One of the possible reasons why this kind of issue occurs is that there could be a bug with the airplane mode or it could also be the doing of faulty network drivers or physical switch that’s turned on, and so on. If you are one of the few users who experience the same issue, then read on as this post will guide you on what to do if your Windows 10 computer gets stuck on Airplane mode. There are a couple of suggestions you can check out to resolve the problem. You can try to check the status of the Radio Management service, flush the DNS cache or you could turn off the airplane mode via system settings. You could also update the network drivers or turn off the physical switch for airplane mode or make some adjustments in the Windows Registry. For more details, refer to each one of the suggestions provided below.

Option 1 – Try to check the Radio Management Service status

• First, tap the Win + R keys to open the Run dialog box and type “services.msc” in the field, and hit Enter to open the Windows Services Manager.
• Next, look for the Radio Management service and select Properties.
• From there, change its Startup type to Disabled and click on the Apply and OK buttons to save the changes made.
• Once done, restart your computer and check if you can now turn off the airplane mode.

Option 2 – Flush the DNS cache

You could also try to flush the DNS cache to fix the “ERR_ICAN_NAME_COLLISION” error. All you have to do is open Command Prompt as an administrator and then execute each one of the following commands sequentially to flush the DNS cache:

• ipconfig/release
• ipconfig/renew
• ipconfig/flushdns

Option 3 – Try turning off the airplane mode via System settings

If flushing the DNS cache did not help in fixing the problem, then you might want to turn off airplane mode via system settings.

• In the Windows Search bar, type “airplane mode”.
• From the search results that appear, click on Airplane mode.
• After that, a window will appear where you have to turn off the toggle button for Airplane mode.

Option 4 – Try to update, rollback or reinstall the Network adapter drivers

The next thing you can do to resolve the problem is to update the Network Adapter drivers by following 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 them.
• Look for the Broadcom Network Adapter and right-click on it, as well as other network adapters that have an exclamation icon, and update them all.
• Restart your PC and see if it helped in fixing the problem.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to roll back the very same drivers from their previous versions 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. To reinstall the network adapter drivers, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Option 5 – Try to turn off the physical switch for Airplane mode

If your computer has a physical switch to turn on or off the airplane mode, then you might want to check that switch if you have one. Chances are, it could be the reason why you’re unable to turn off Airplane mode on your computer.

Option 6 – Try to make some adjustments in the Registry

• Tap the Win + R keys to launch the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESystemCurrentControlSetControlClass
• From there, edit the registry value of “RadioEnable” to “1”.
• Exit the Registry Editor once done, and restart your computer.

What Does 0x8007045D Error Code Mean?

The 0x8007045D error code is an I/O (input and output) error that is associated with the registry. It indicates that the Windows operating system has become overloaded with invalid system references in the registry. This may prevent you from executing reading and writing to and from devices successfully.

Error Causes

Registry is the main database of your PC. This portion of your computer saves all the activities that you perform on your PC including the junk files, temporary internet files, invalid entries, bad registry keys, and more. This clutters the hard disk. If the unnecessary files are not removed from the registry, it may lead to I/O errors like 0x8007045D. On the hard drive, some parts of the drive may fail to function. If this is not fixed on the time it may lead to serious disk damage and registry corruption eventually resulting in system failure. System failure can make you lose all the valuable data saved on your system for good.

How to Fix the Error Code 0x8007045D?

Error codes on your PC are like warnings. These codes indicate that your PC has some issue. Therefore ignoring it is not wise. To spare yourself from such serious PC damages, it is advisable to take correct measures timely instead of prolonging and making the situation go from bad to worse.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

There are times when system files get corrupted and if the Windows Update process finds the system’s integrity questionable, chances are, the update, upgrade or the installation may fail and you will only be getting an error code 0x80073712 instead of completing the process. The error code 0x80073712 indicates that a file needed by the Windows setup or the Windows Update is most likely missing or damaged. To resolve the problem, here are some suggestions you can try.

Option 1 – Try running the DISM Tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be causing the error 0x80073712. To run the SFC command, follow the steps given below.

• 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.

Option 3 – Try running the Chkdsk utility

You can also try running the Chkdsk utility to resolve the Windows Update error 0x80073712. 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 commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed.

Option 4 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 5 – Try running Microsoft’s online troubleshooter

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors.

RSAT or Remote Server Administration Tools for Windows 10 is a collection of programs for IT experts.

Method four: Run System Restore Tool

Another effective manual repair method relates to System Restore. This tool enables Windows users to restore their computer to an earlier period of time in which the error code was not present. When done properly, it can effectively resolve error code 0x8007007e. Before running this tool, however, be sure you select a time in which all important files and programs are present so as not to lose them.

Method Five: Use 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.

On September 18th, 2017, Cisco’s Talos announced that CCleaner, a popular utility with billions of worldwide users, had been compromised by hackers, and was used to unwittingly distribute hidden malware in its installer. Later in the day, Piriform, the publisher of CCleaner, confirmed the problem.

Undetected by all but 1 major antivirus including CCleaner’s own parent company, this occurred for over a month and impacted over 2.7 million users. Users of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 for 32-bit Windows are affected. These downloads were live on CCleaner’s official site from August 15th to September 12th, 2017. Anyone who downloaded the program during this time could be affected. The company claims that while the hackers set up the backdoor and many users were impacted, that the perpetrators have been arrested and that the malware never successfully performed its full task and compromised user’s PCs or sent out their data; in the wake of recent security breaches such as Equifax, users are understandably worried. Given the severity of the threat of hacking and data theft, users should take action immediately if they have CCleaner.

Technical Details of CCleaner Malware Injection

First reported by Talos, the malware, which was hidden in the CCleaner installer without the publisher noticing (despite them being owned by Avast, a massive Anti-virus company), modified a core program DLL file to evade detection, and creates several registry keys. Not only were these files not flagged by any major Anti-Virus, but they were also even digitally signed by Piriform via their Symantec certificate, meaning your PC and security program would likely whitelist and trust the malicious installer. The malware gathers personal information on a user’s PC, including IP address and running programs, and sends it to a remote server. In our testing, the program sent data to IP 216.126.225.148.

Restore Your PC (If Possible)

As of the publication of this article, there have been no assurances given that updating or even uninstalling CCleaner will remove the malware is installed. The only action thus far has been shutting down the remote server where user data was being sent has been shut down by authorities. For this reason, it is best to remove the underlying malware separately, as its presence represents a serious security threat. Unfortunately, as this could have been installed as far back as August 15th, 2017, your System Restore points may not go back that far, or even if they do, restoring to such an outdated point may cause unintended problems with other programs you use and potentially lost files and data. Manually backing up files and doing a full format or clean Windows installation would likely be successful in fully removing the malware, but is extremely time-consuming and can be difficult for many PC users. Unfortunately, this makes a PC Restore or format an unattainable option for many.

Update CCleaner to the Latest Version

While CCleaner has told users to update to the latest version of the program. Prior to doing so, we recommend fully uninstall CCleaner, ensuring you check its program files folders and registry keys, manually deleting any remnants, and then re-downloading the latest version from the official site and reinstalling clean.

There is a built-in tool in Windows 10 the Disk Cleanup Utility which can help you restore hard disk space by removing temporary files, Thumbnails, old Windows files, Windows Upgrade logs, Delivery optimization files, and many more. However, from time to time, this built-in tool also experiences some issues. One of these issues is when it gets stuck on Windows Update Cleanup. Read on to find out what you can do in such a case. When the Disk Cleanup Utility is stuck on the Windows Update Cleanup, the process could be slow and take a long time to complete when purging the files. If this happens, click on Cancel to close the dialog box. After that, try running the Disk Cleanup Tool again as administrator and check if the files that you want to clean is still there or not. If it isn’t there, then this means that the cleanup has been done, otherwise, you need to refer to the options given below.

Option 1 – Try to manually delete the contents in the SoftwareDistribution folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer and then try to run Windows Update once more.

Option 2 – Try to manually delete the contents of the Windows.old folder

The Windows.old folder is the one that holds the older version of Windows when you upgrade. It comes really useful when you want to revert to the previous version of Windows 10. Thus, you can delete the Windows.old files in case the cleanup tool is stuck.

Option 3 – Try running Disk Cleanup in a Clean Boot State or Safe Mode

Another thing you can try is to restart your computer in a Clean Boot State or Safe Mode. Chances are, there are some programs that are preventing the Disk Cleanup Utility tool to run properly. After you restart your computer in a Clean Boot State or Safe Mode, try to run the Disk Cleanup tool again and then see if it now works or not.

Option 4 – Run the Windows Update Troubleshooter

You might also want to run the Windows Update Troubleshooter as it could also help in fixing this issue. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Run the DISM tool to fix the corruption in the Component Store

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

If Error Code 0xc00000e9 appears on your screen, there is no cause to panic yet as there are different ways to fix this. Here, I will list down different methods to get your computer back on track:

1. Check peripheral connections
2. Check your SATA cables
3. Check your hard drive
4. Check your BIOS settings

Quick Fix 1. Check Peripheral Connections

1. Turn off your computer.
2. After the computer has been shut down, take off all the peripherals or the USB cables that are connected to your USB ports. This includes even the keyboard and the mouse. We just need to have only the monitor plugged in for this one.
3. Turn on your computer and see if it starts as it normally does.
4. If it does, try connecting back your external devices or peripherals one by one until you find the one that causes the error.
5. Once you trace the device that’s causing the error, you will have to change its USB cable and update its driver to support your operating system.

Quick Fix 2. Check your SATA cables

It is possible that what causes a barrier between your operating system and your hard drive from communicating is the SATA cable used. For example, if you’re using an older SATA with a SATA III port, there might not be adequate support for the transfer of data from one another. Or, the problem might be a loose SATA cable which would still require you to buy a new one to replace your loose or damaged cable. To check if your SATA cables are causing the error, simply follow these steps:

1. Turn off your computer.
2. Carefully open its case.
3. Check the hard drive and the SATA port where it’s connected.
4. Try to use a newer cable and connect it to your SATA port. (If you used a SATA II cable, you can see if a SATA III cable is more compatible.)
5. Replace your SATA cable with a newer one if Step 4 proves to be successful.

Quick Fix 3. Check your hard drive.

1. Try to use a different hard drive and see if error code 0xc00000e9 still appears.
2. If it works out just fine, then the problem might be physical damage to your hard drive and would need to be repaired depending on the case. Just simply take it to a technician and let him know about the issue.

Quick Fix 4. Check your BIOS settings

1. Restart your computer.
2. Once your computer starts, press and hold the ESC, F2, F12, or DEL key to go to BIOS settings.
3. You will then be redirected to the BIOS Setup Utility screen. From here, go to Boot options.
4. In the Boot Options, see if your first boot device is your hard drive. If it isn’t, press the arrow key to select the hard drive and move it to the top of the boot device list.
5. Save the settings.
6. Reboot your computer.

Note: If all the methods above do not work, the problem might be on your drivers and you might need to update them. You can update your driver in two ways: Manual driver update and Automatic driver update. You can find procedures online in updating your drivers.

If you recently upgraded your computer or if you’ve just switched to a new Windows 10 PC, the most common errors you might encounter are the Windows Activation errors. This issue boils down to the Windows Activation server which has either failed to validate or recognize the license tied to the digital account. In this post, you will be guided on how to fix an activation error in an organization with an error code 0x8007007B. It contains this exact error message: “We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.” Various computers are activated via the KMS licensing (Key Management Server) in organizations. Computers that are activated using this process do not get a permanent activation and have to stay connected to the organization instead of for at least 7 months or 180 days. It is common in Pro and Enterprise versions that are deployed in bulk for at least hundreds or thousands of computers. So imagine a user with a personal computer in the office who decided to leave the organization but will still have an activated Windows key. And so to prevent that from happening, organizations use the KMS licensing. Another possible cause of the error is in case some user used an organization key and later on, the PC just got upgraded or downgraded to a version that is not compatible with that copy of Windows. To fix this Windows Activation error, here are some suggestions that might help.

Option 1 – You can try connecting to the organization’s network and activate the computer. But before that, you need to first check if the computer actually belongs to an organization or not.

• Tap the Win + R keys to open the Run dialog box.
• Type “cmd” and hit Enter to open an elevated Command Prompt.
• After that type the vbs /dlv command and hit Enter to execute it.
• Next, check if the Product Key Channel says “GVLK”. If it does, then it means that your computer was activated using volume licensing.

Option 2 – Change Licence Key

If you’ve recently left an organization then it’s best if you buy another copy of Windows 10 and then change the license key. This time, make sure that the license key is for the same version of Windows. However, if it’s different, you need to format your computer.

Option 3 – You can try activating Windows 10 using a 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 4 – If you think that the issue is caused by some hardware changes, you can try using the Activation Troubleshooter.

There are times when users already have the license keys and were able to activate Windows. However, it doesn’t last long and only works for a while and it’s suddenly throwing up an activation error like this one. To use the Windows Activation Troubleshooter, just go to Settings and to Activation and then run the troubleshooter from there. If you've made some modifications to your hardware, you have to click the “I changed hardware on this device recently” option for further suggestions.
