How to Fix Tcpip.sys Blue Screen Error in Windows 10

Every time a new drive or any storage device is connected to a Windows 10 computer, the operating system tends to allot a drive letter to it automatically. Not only that, as the OS also maps the location of the drive which helps it point the letter to the exact port location of the drive and serve requests from the user. As a result, it builds up a bit of cache as per the pattern in which the user uses the storage of the computer. This whole process is known as “Auto Mounting” which works for hard disks or optical drive readers that are connected using the SATA ports and even for USB drives that are connected using the USB ports. There are several ways you can enable or disable the Auto-Mount feature in Windows 10. You can do it using the MountVol tool or the Registry Editor or the Diskpart utility. Before you proceed, it is recommended that you create a System Restore point first so that you can always undo the changes you made in case anything goes wrong.

Option 1 – Enable or disable Auto Mounting via MountVol tool

In this option, you will be using the mountvol command in the Command Prompt. Refer to the steps below.

• Tap the Wins key once and type in “command prompt” in the field.
• From the search results, right-click on Command Prompt and select the “Run as administrator” option to run it with admin privileges.
• Next, type the following command and tap Enter to enable the Auto Mount feature:

mountvol /E

• On the other hand, if you want to disable the Auto Mount feature, type the following command instead:

mountvol /N

• After that, type the command below to remove all the previously assigned drive letters:

mountvol /R

• Finally, restart your computer.

Option 2 – Enable or disable Auto Mounting via Registry Editor

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and tap Enter to open the Registry Editor.
• After that, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesmountmgr
• Next, look for a DWORD named “NoAutoMount”. If you can’t find a DWORD with that name then simply create a new DWORD with the same name and make sure that the base is selected to Hexadecimal.
• Now double click on that DWORD and change its value to 0 if you want to enable it, otherwise, input 1 as its value to disable it.
• Restart your computer.

Option 3 – Enable or disable Auto Mounting via Diskpart utility

• Tap the Wins key once and type in “command prompt” in the field.
• From the search results, right-click on Command Prompt and select the “Run as administrator” option to run it with admin privileges.
• After opening Command Prompt as admin, type the following command and hit Enter to launch the Diskpart utility:

diskpart

• After that, a User Account Control prompt will appear. Just click on the Yes button.
• Next, type the following command and hit Enter:

automount

• Following the command you entered, you will an output that either says, “Automatic mounting of new volumes enabled” or “Automatic mounting of new volumes disabled” which means you can use it to check the status of Auto Mount.
• Now if you want to enable the Auto Mount feature, type the following command and tap Enter:

automount enable

• And if you want to disable the Auto Mount feature, just enter the following command:

automount disable

• To remove all the assigned letter and history of drives that were connected previously, type the following command:

automount scrub

• Finally, restart your computer.

There are times when you upgrade or install Windows 10 on an old computer and the Aspect Ratio of the screen is in a mess. This issue occurs when a new Windows version does not support the GPU or the driver does not work in Windows 10. And in such cases, Windows uses a generic driver which does not support all the resolution as well as the correct aspect ratio. So in this post, you will be guided on how you can fix the issues with the screen aspect ratio in Windows 10. It could be that your screen has an aspect ratio of 16:9 but after the upgrade, you changed to screen resolution, and is now set to 16:!0. And later on, you found that you are unable to go back to the previous aspect ratio. Thus, you will notice that everything on the screen might look stretched. You might be wondering if it’s possible to change the aspect ratio in Windows 10 directly even if the GPU does not have the compatible driver, well it really isn’t. However there is another way to resolve the problem. Refer to the options given below to get started.

Option 1 – Try using the Compatibility Mode

The first thing you can do is to run the driver in a Compatibility Mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• You also have the option to change the DPI settings and see if that helps. Then click the Apply and OK buttons.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 2 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

Option 3 – Update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• 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.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

If you suddenly encounter a Blue Screen error that points out to either the mfewfpk.sys and epfwwfp.sys files, then this post might help. Both of these files are created by third-party software. The mfewfpk.sys file is created by the McAfee security software while the epfwwfp.sys is created by the ESET Antivirus. These files are residual files and sometimes it blocks upgrading Windows 10. Aside from blocking Windows 10 upgrade/update, these files can also cause a Blue Screen error after an upgrade which leaves your Windows 10 computer useless. When you get a Blue Screen error caused by any of these files, you will see an accompanying error message that states, “DRIVER IRQL NOT LESS OR EQUAL”. To fix this Blue Screen error, you can check out the suggestions laid out below but before you do that, you need to create a System Restore point first as it can help you undo any unwanted changes. In addition, make sure to also boot your computer into Safe Mode with Networking before you troubleshoot.

USB ports, just like any other ports, also comes with a power rating. The default power output of a standard USB port is 0.5 amperes and if you notice, mobile phones charge slowly on USB ports which explains why. There are times when Windows may throw an error or warning that says, “Power surge on the USB port”. This kind of error occurs when a connected device tried to draw more power and the error comes as a part of that notification so when you select it, it will say,

“A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device”.

To easily fix the problem, you can try to disconnect the device and click on Reset and if you click on Close, the port will not work until you unplug it and then restart your computer. On the other hand, if disconnecting the device did not resolve the problem, you can try running the Hardware & USB troubleshooter or use a USB hub. You can also try to reinstall, uninstall or roll back the USB drivers or run the OEM diagnostics. For more information, refer to each one of the potential fixes provided below.

Option 1 – Try to run the Hardware & USB troubleshooter

As of the time of writing this article you no longer need or are required to have a password if you plan to log in to your Microsoft account. Microsoft explored various options for account security and came to the conclusion that passwords are obsolete. Microsoft is letting you access your account through the Microsoft Authenticator app, Windows Hello, a security key, SMS verification, or email verification code. All of these methods are way better in terms of security than passwords.

How to turn these features on?

To get rid of your Microsoft password, the process is simple. You simply need to go to your Microsoft account, click “advanced security options,” then “enable passwordless accounts” under the Additional security section.

Windows is one of the most popular operating systems in today's world. Plenty of software and plenty of hardware is working on it without any issues. In order for Windows to deal with this ever-growing hardware and in order for hardware manufacturer's to have stable products in the Windows environment is accomplished via Drivers. A driver is a small piece of software whose sole purpose is to control and communicate with specific hardware and create a bridge between it and Windows itself. it is made in such a way that even if it brakes the rest of the operating system will continue working uninterrupted. Having updated drivers means better performance and better stability for device performance so it is crucial to have the latest drivers installed. Outdated drivers can also lead to some security issues which could be exploited by malicious applications. Here, in today's article, we are presenting you with 4 ways on how to keep your drivers updated and tidy for best performance and stability. The list goes from the most simple way to the most complex and time-consuming one.

1. Use one-click solution, DRIVEFIX

   The most simple and most straightforward solution, install DRIVEFIX, and with only one click on a mouse button, you can have all drivers fixed and updated. This application is made for this purpose and it is doing its job pretty well.

2. Update Windows

   Windows updates come with new drivers for new hardware and with newer versions of existing ones, do update on regular basis and you should have all of your drivers up to date.

3. Download drivers from the manufacturer's website

   Go to the manufacturer's website for your device and download and install the latest driver package.

4. Use device manager to update drivers

   Go to the device manager and right-click on the device which you would like to update the driver. Choose update device driver.

If you are trying to access a particular file on your Windows 10 computer either to open, rename or delete it, and you suddenly encounter an error stating, “Could not find this item. This is no longer located in [Path]. Verify the item’s location and try again”, read on for this post will help you out in resolving this issue. If you are able to find and view a file on your computer, you should have clear access to it. And since you are seeing an error message when you try to do something about this file, you are not able to do anything with the file. There are times when this error pops up with the files created by third-party services and that the file’s extension is not defined properly. On the other hand, there are also other obscure causes for this error. To fix it, here are some suggestions you can try.

Option 1 – Delete the file using Command Prompt

If you wish to delete the problematic file and weren’t to, you can use Command Prompt.

• In the Start menu, type in “Command Prompt” to search for it or you could also click the search button right next to the Start menu and then right-click on the related result and select the option “Run as administrator”.
• Once you’ve opened Command Prompt, copy and paste the command given below and tap Entre after you do so. You also have to make sure that you key in the correct path where the file is located as well as its name.

rd /s \?X:badfolderpath Note: In the command above, “X” is the placeholder letter so you must input the letter that corresponds to the drive’s letter where the file is located.

• After that, you will see the “Operation completed successfully” message on your screen. If you don’t, check if you’ve really inputted the correct location of the file or its name.

Option 2 – Use a Command Prompt tweak to rename the file

If you don’t want to delete the file and only want to rename it, you can apply some tweaks using the Command Prompt. Make sure to follow the steps carefully.

• In the Start menu, type in “Command Prompt” to search for it or you could also click the search button right next to the Start menu and then right-click on the related result and select the option “Run as administrator”.
• After opening Command Prompt, type in “cd” followed by the path where the file is located with this format – “C:\Folder1\Folder2\Folder3”. However, you have to omit the problematic file this time. To put it simply, the last folder in the command must be the folder where the file is located.
• After inputting the command, tap Enter on your keyboard and then use the set of commands given below. Note that each command is a new line so you need to tap Enter after copying each line.
  • DIR /A /X /P
  • RENAME (the current name of the problematic file) (a non-problematic name)
  • EXIT

Note: Make sure that you only input the current name and the new name separated by a space. You must not write the brackets in the command. If everything goes well, you will now be able to operate the file like you used to before.

Option 3 – Use Command Prompt to delete the file without any extension

This option applies to cases where the affected file does not have any viable extension which means that Windows does not really know what to do with it and it only displays the “Could not find this item. This is no longer located in [Path]. Verify the item’s location and try again” error message. It usually occurs with the files created by browser plugins that are mostly from Mozilla Firefox. To delete these kinds of files, here’s what you have to do:

• Follow the first two steps from the previous option above so you can navigate to the location of the file accurately just be careful in inputting the folders.
• Don’t forget to tap Enter right after each command and then use the next command below so you can delete the affected file which has no extension:

del *.*

• After you’re done, open the File Explorer and then check if the file is now deleted or not.

Option 4 – Try using another workaround without using Command Prompt

This option is a lot like a workaround but it definitely gets the job done for you. It’s ideal for you if you do not want to deal with Command Prompt and only want to do everything in a graphical environment. To get started, follow the steps below.

• Look for the affected file or folder on your PC using File Explorer. Once you found it, right-click on it and select the “Add to archive” option from the context menu.
• Once the archiving options window pops up, look for the “Delete files after archiving” option and make sure that you select it then click OK to start archiving the folder or file. After that, you should now notice the file no longer exists.
• After that, delete the archive file as well.

Any modifications in a computer, either big ones or small ones can definitely trigger some errors which is why you have to be careful when you modify the system setting. One of the errors you might encounter when you’ve modified your computer is the WHEA_UNCORRECTABLE_ERROR 0x00000124 Blue Screen Error. According to the error data provided by the Windows Hardware Error Architecture or WHEA, aside from system modifications, you could also encounter this error if your computer has a hardware failure which could be due to a hard drive, RAM, or any other hardware component. In most cases, it is related to physical hardware failures which might have something to do with defective hardware, heat-related, memory as well as a processor that is starting to fail or has already failed. To fix the WHEA_UNCORRECTABLE_ERROR 0x00000124 Blue Screen error, here are some suggestions you have to check out.

On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions or disable them.

Option 6 – Try running System File Checker or SFC scan

You could also run System File Checker or SFC scan to fix the BSOD error. It 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. 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.

• Reboot your PC.

Option 7 – Try to disable the Digital Driver Signature Enforcement

• Reboot your computer from the Start menu.
• Then select the option while pressing the Shift key. This will open the Advanced Boot menu.
• From there, click on Troubleshoot and select Startup Settings.
• Now select the “Disable driver signature enforcement” option using the arrow keys on your keyboard and then restart your computer normally.

If you encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics. If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot. There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.

Option 1 – Try checking the connection with the boot drive

If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.

Option 2 – Try changing the boot order

You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.

Option 3 – Try to rebuild the BCD files

The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
  • bootrec /FixMbr
  • bootrec /FixBoot
  • bootrec /ScanOS
  • bootrec /RebuildBcd

• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed the “Boot Device Not Found” error.

Option 4 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

• Boot your computer using the bootable Windows 10 USB drive.
• Next, click Next when you get to the Welcome Screen.
• Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
• After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.

diskpart

• Now type the following command:

list disk

• From there, select your primary disk by typing the following command:

select disk number

• After that, list all the partitions on the selected disk by entering the following command:

list partition

• The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
• Now type the following command to select the partition that is usually around 100 MB in size:

select partition number

• Finally, type the following command to mark the partition active:

active

• Then type the “exit” command to exit the disk part utility.

Once it’s done, the primary drive should now be active and you should now be able to boot into your computer without the “Boot Device Not Found” error.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.
