KMODE_EXCEPTION_NOT_HANDLED – What is it?

Some users installing or upgrading to Windows 10 experienced the theKMODE_EXCEPTION_NOT_HANDLED Blue Screen of Death (or commonly known as BSOD) error. This error can be due to different types of things, ranging from software to driver issues. When you experience this BSOD error while trying to install Windows 10, it will prompt you to restart your computer every single time you experience it. In most cases, you will also not be able to proceed with the Windows 10 set-up.

Solution

Error Causes

The “KMODE_EXCEPTION_NOT_HANDLED” error is normally caused by:

• Hardware incompatibility
• A faulty device driver or system service

Further Information and Manual Repair

You won’t be able to successfully upgrade or set up Windows 10 if you continue to encounter this BSOD error. Note that this error will always prompt your computer to restart every time it happens, preventing you from completing the Windows 10 set-up.

If you’re not tech-savvy or not capable of debugging this issue, it’s highly advisable to proceed with the basic troubleshooting techniques available in this link.

After troubleshooting, below you’ll find a few solutions to rectify the issue.

Method 1 – Check The Cause of The BSOD Error

Two common causes of the KMODE_EXCEPTION_NOT_HANDLED issue are hardware incompatibility and faulty device driver or system service.

If you experience this error, check first if any of your newly installed hardware is compatible with Windows 10. You can find the required hardware for Windows 10 from this link. 

If all your hardware is compatible with Windows 10, you might need to check the device driver or system service. Review the bug check message. If any of the drivers you have is listed in the message, either disable or uninstall them before upgrading or setting up Windows 10.

You might also find it useful to check the System Log available in the Event Viewer for other error messages that can help you figure out the driver or device that’s causing the error. Running hardware diagnostics can also be useful.

Method 2 – Disable (or preferably uninstall) Software Before Upgrading

If you’re upgrading Windows 10 from Windows 7 or Windows 8.1, you might need to disable or uninstall the software first. First, try uninstalling your Antivirus utility before starting the upgrade. Restart a few times before starting the Windows 10 installation. If you’re upgrading using the Windows 10 update, make sure that you disconnect from your Wi-Fi or Internet LAN (Ethernet) connection as soon as the download reaches 100% before attempting to start the set-up. Other users also reported that the cause of the KMODE_EXCEPTION_NOT_HANDLED issue is BitDefender. If this is what happened in your case, it will show in the error message such as KMODE_EXCEPTION_NOT_HANDLED (bdselfpr.sys). Users reported that a common solution for this is renaming the file. In the case of BitDefender, try renaming it to bdselfpr.s__. However, make sure to do this cautiously. Sometimes, renaming a file will even do more damage than good.

Method 3 – Disable/Disconnect From Hardware

If you’re connected to any general USB devices (such a smart card reader), disable it. If your computer is connected to other external devices, disconnect all of them. Examples of this include gaming controllers, printers, external hard disk, USB keys, and other non-essential devices).

Method 4 – Other Troubleshooting Steps

Other troubleshooting steps include:

• Upgrade using an .ISO file, instead of directly upgrading from Windows Update. When you do this, make sure you’re disconnected from the Internet during installation. If the process started and you forgot to disconnected, it’s best to restart the installation.
• If you’re connected to a domain while trying to set up Windows 10, disconnect and use a local account.
• If you’re using a SCSI hard disk, connect a thumb drive with the drivers for your storage device. While Windows 10 is setting up, click on the Custom Advanced Option. Using the thumb drive, use the Load Driver command to load the SCSI drive.
• Another possible cause of this error is due to BIOS incompatibility. BIOS issues can be solved by upgrading your version of your system BIOS. If you don’t know how to do this, refer to your BIOS manufacturer’s website.

Method 5 – Use A Trusted Automated Tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

A lot of Windows 10 users prefer the black theme on their computers and when you see anything but black it can get quite annoying. Such as is the case of the Taskbar which, as you know, is usually dark, however, when you take a look at the Cortana search bar, instead of seeing black, you’ll see that it has turned white. To fix this issue, read on as we will provide you some options you can try to set the Cortana search bar back to black. Before you proceed, take note that the options provided below will change all white search boxes to black and that one of these options needs administrative privileges.

Option 1 – Try changing the default App mode

As you know, Windows 10 has two modes, namely the Light and the Dark. Thus, you can switch to the Dark mode so that your Cortana search bar will be black as well. However, remember that it will completely change everything into dark mode so there will be no more Light mode elsewhere.

• First, you need to click on the Start button and then click on the cog icon to open the Windows 10 Settings.
• Next, from the Settings Menu, select Personalization and then select Colours from the left pane.
• Then scroll down until you see the “Choose your default app mode” option and select “Dark”.

After you apply the changes, it will change the Cortana search bar into black instantly. Aside from that, you will also see the User Interface changing into dark mode.

Option 2 – Try changing the Registry value

If you are well-versed in editing registry keys, then you need to try this option. But before you go over the steps below, make sure that you create a System Restore point first so that if anything goes wrong, you can always go back to how it was before the changes were applied.

• Tap the Win + R keys to open the Run prompt.
• Then in the field, type in “regedit” and hit Enter to open the Registry Editor. If a User Account Control prompt appears, just click Yes.
• Now that you’ve opened the Registry Editor, navigate to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionSearchFlightingWhiteSearchBox

• After that, double-click on the “Value” key located on the right pane and set the value to “0” instead of “1” and then click Ok to save the changes made. You should now see a black or grey text box color instead of white.

Option 3 – Try changing the Region

In some forums, a lot of users stated that changing the Region also worked out for them in changing the white Cortana search bar to white. Thus, you need to change the region settings of your computer temporarily. To do so, follow the steps below.

• Type in “Regional Settings” in the box and then click it as soon as it appears from the search results.
• Next, make sure to select a region where Cortana is not available.
• Then select apply to that region. After that, it will change the Cortana search bar color to black.
• Now sign out and sign back in and revert to the original settings. But the changes you made earlier in Cortana will still remain.

Microsoft wants to escalate the situation from Australia to the EU, what a surprise. Hello all and welcome to another news article, this time we are focusing on Microsoft pushing the EU to accept law proposition from Australia. For all of you who are not familiar with the given situation let me quickly explain. The feud began when the Australian government proposed a new law that targeted Facebook and Google specifically. The government said that it believed that both of the tech giants were using content from news outlets without paying. Have you ever seen the little news snippets that Google or Facebook sometimes show its users to keep them up to date? These are lifted directly from news websites, and the Australian government claimed that this practice meant that people didn't bother visiting the news website. This then staved news websites of revenue. As such, the government put forward a new law that would mean Google and Facebook would have to pay the source website for every time they displayed a news snippet. Facebook responded by removing its Australian news coverage in light of the law. Google, however, put up a fight. It argued that its snippets encouraged people to click on it to read more, thus driving more traffic to the news website. It also said that such a law would be too expensive to maintain in the long run. As such, Google threatened to remove itself from Australia if the law passed. This was likely a scare tactic, as 95 percent of Australian web users use Google; however, it actually opened the door for its rival, Microsoft. Microsoft saw how it could push its own search engine BING to replace google. It of course went and reached the Australian government to assure them that BING is more than capable to fulfill its needs and fully abide by the proposed law. Now Microsoft knows that if this law passes it could see a similar situation happening in Europe and it is pushing it. US News reported on how Microsoft plans to encourage EU countries to adopt this new law too. The company has teamed up with the European Publishers Council and News Media Europe to make the following statement: Publishers might not have the economic strength to negotiate fair and balanced agreements with these gatekeeper tech companies, who might otherwise threaten to walk away from negotiations or exit markets entirely

Error Code 0x8007001 - What is it?

Error Code 0x8007001 occurs during installations that take place in Windows 10.  Various versions of this same error have also been present in previous editions of the software and the methods to resolve the error across these versions are the same

Common symptoms include:

• Inability to complete the installation process for updates, programs, and system versions.
• Installations quitting out in the middle of the process, particularly as the files are unpacked.

Several solutions for Error Code 0x8007001 require the user to complete semi-complex tasks. If you aren’t comfortable with the processes necessary to finish the methods below, make sure that you get in touch with a certified professional who is familiar with the Windows operating system to assist you in the resolution of the error code.

Solution

Error Causes

In many cases, Error Code 0x8007001 is caused by an installation disk that is not functioning properly or installation files that have been corrupted or changed. When this is the case, the operating system will not be able to begin actually installing the files and will instead hang up as the files are unpacked from the installation set.

Further Information and Manual Repair

For Error Code 0x8007001 to be repaired properly, the missing or corrupted installation files need to be repaired or the system needs to be able to recognize the files that it is missing. This can require some advanced computing knowledge. If you don’t feel comfortable with the idea of undertaking the methods below on your own, contact a computer repair technician who can assist you in following these steps.

Method One:  Load the Install Files on an Alternative Disk

In some cases, the operating system simply cannot recognize the installation files that are present on the disk in question, whether it is on a hard drive, a set of downloaded files, or files from a flash drive. If this is the case on your particular machine, the simplest way to work around the problem is to load the installation files onto an alternative disk source, whether it be a flash drive, CD, DVD, or secondary hard drive. After these files have been properly loaded onto that alternative disk, attempt to run the installation from the alternative source instead.

If this method is successful, it means that the system may have had trouble recognizing the files involved in the installation from the first source, but that the files themselves were not corrupted or changed.

Make sure that you save the alternative disk source after your installation is complete in case you ever need to do a fresh installation on your machine.

Method Two:  Clean Your Disc and Your Drive

If you are installing files from a DVD or CD, check to make sure that the back of the disc is free from scratches and dust. If there are no visible marks on the disc, you may need to open up your disk drive to see if there is a build-up of dust or debris inside of the drive. If this is the case, simply clean your drive and re-attempt your installation process from the included disk.

Method Three:  Run the Windows Update Troubleshooter and Update Your Programs

If the error code is still appearing on your machine, you can open up your Windows Update tool and run the troubleshooting wizard, which will then scan your machine to see if there are any potential problems that it can fix. Next, run the Update tool itself if there are any updates that need to be performed. Sometimes, this can resolve the error at hand. Make sure to restart your computer after any updates or changes have been made so that you can ensure that they are applied by the operating system appropriately.

Method Four: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

The System32 folder contains vital configuration and information that are essential to the operating system. It is located inside the “Windows” folder and it consists of important DLL files as well as executable files. You probably have noticed some errors that have the “System32” word in them but that does not necessarily mean that the System32 folder is the one that triggers them as these kinds of errors have only occurred when some important files are corrupted or missing. Some users recently reported that each time they start their computers, the System32 folder will automatically open up in the File Explorer. If you encounter the same problem, read on as this post will guide you on what to do to fix it. This kind of issue is most likely caused by service or application interference – it is possible that there is a third-party application installed in your computer or a Windows service that triggers the System32 to pop up during startup. It is also possible that this is a result of system modification. Thus, you need to identify the third-party program or restore your computer to its previous state.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

Option 2 – Perform System Restore

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys 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 and see if the System32 folder still pops up at startup or not.
