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.

Dynamic Wallpapers introduced with Mojave Update in macOS are pretty cool. Dynamic Desktop is a feature introduced in macOS Mojave (10.14), in which the desktop background changes according to the time of Mac's current location. If Location Services are turned off the Privacy pane of the System Preferences, then the time zone specified in the Date & Time preferences will be used. To apply macOS Dynamic Wallpaper on Windows 10 we need to download & use WinDynamicDesktop, a free application that lets you apply macOS Dynamic Wallpaper. After the installation, you will be asked to Configure the Schedule. While doing that you need to make sure that you enter your location correctly. You can even set specific sunrise and sunset timing by selecting “Use specific sunrise and sunset times” and changing the Sunrise and Sunset times manually. Now, you will be greeted with some of the coolest dynamic wallpapers in the market. Select a theme of your choice, click on the Download button (file size can range between 20-200 MB), and click Apply to enjoy macOS Dynamic Wallpaper on Windows 10. If for some reason you want to go back to the default Windows theme but not necessarily delete the application then right-click on the WinDynamicWallpaper icon from the taskbar, click Select Theme, select None (from the theme section) and click Apply.

We’ve already covered disabling Security Questions If you want to disable Security Questions on your Windows 10 computer then you’ve come to the right place as this post will guide you in doing exactly that. In this post, you will be disabling Security Questions using a PowerShell script. This PowerShell script is called “Update-AllUsersQA”. It is designed to remove or disable the security questions and answers for local users on a Windows 10 computer. It lets administrators take control of the security questions in the environment and at the same time minimizes the risk that comes with them. If a user has a Microsoft account that’s configured to sign in to Windows 10 then he will not probably notice the Password Recovery questions. On the other hand, if he has a chosen local account for installing Windows, he will e prompted to create three security questions that can be used to reset the password and log into the Windows 10 account in case there is any misfortune. However, if you do not have much use for these Security Questions, then you can definitely have them disabled using a simple PowerShell script which you can download from GitHub. For more details on how to disable security questions in a Windows 10 machine, refer to the steps provided below. Step 1: You need to first download the .ps1 file from the GitHub repository. Step 2: Once you’ve downloaded the file, open the PowerShell window with admin privileges. Step 3: After that, navigate to the folder where you had saved the .ps1 file. Then copy the address of the folder location. Step 4: Next, change the directory by using the following command:

cd "folder location address"

Step 5: After that, enter the following script to disable the security questions:

Update-AllUsersQA

Once you’ve completed the steps above, the Security Questions should be disabled and you will be notified with a message stating that the feature has been disabled. On the other hand, if you have a change of heart and you want to enable the Security Questions back, here are some steps you need to take: Step 1: First, open the PowerShell window as admin. Step 2: Next, run the same script with one more parameter such as:

Update-AllUsersQA -answer SecretAnswer

Step 3: And that’s about it. Do not forget to replace the Secret Answer with your preferred one and once you’re done, it will be set as the answer for all the Security Questions. Step 4: Now all that’s left to do is go to the Settings app to change the answer to the questions and you should be good to go.

The file is too large for the destination file system is the error when you try to copy a file larger than 4GB on a drive formatted in the FAT32 file system. FAT32 is the old file system used in previous Windows versions and it was replaced by superior NTFS, altho FAT32 is still used because of its compatibility fact that it could be accessed in various operating systems its disadvantage among others is that it can not hold files larger than 4GB in size. This refers to the size of a single file, so if you have a file that is this large and when you try to copy or move it on a drive formatted in FAT32 you will get this message, and the operation will not be able to complete.

Format drive

In order to actually transfer the file in its glorious size, I am afraid that you will need to format destination drive in NTFS or if you have data on drive which you do not want to lose with formatting, use third-party software to convert file system from FAT32 to NTFS without losing data. I would recommend AOMEI partition assistant, it is a free and proven application letting you both manage your partitions and convert any one of them into another file system without data loss. You can get AOMEI here.

Split file

Another option if you are not keen on installing third-party tools or formating is to divide large files into smaller ones that are less than 4GB in size. You can use any archiving application since built-in Windows ZIP support will not let you split file into various different sizes. The best tool in my humble opinion is WinRAR, but you can choose any proven one. When file is split into parts less than 4GB in size, you will have no issues copying or move the file to the destination drive.

Have you been feeling anxious in the digital space? Feeling like you have a million eyes on you each time you visit a website? It can definitely make you uneasy. Luckily there’s an easy fix, and it’s called a VPN.

In this article we’ll take you through the basics of what a VPN does and some of the biggest benefits you can reap from buying one.

VPN: definition and how it works

VPN stands for Virtual Private Network, so its name already says a lot about what it does. 

A VPN is specialized software that keeps your browsing private and secure. Essentially it hides your identity, preventing possible cyberattacks and data theft. This is especially important in cases of public network use, where you’re highly exposed to potential threats.

To be more specific, this software encrypts your Internet Protocol (IP) address by filtering it through a server hosted by the VPN provider first. That way, it prevents your Internet service provider, third parties and lurking online thieves from tracking the actual you.

Some providers, such as Surfshark VPN with its IP Rotator feature, even make it a habit to frequently change your IP address to further protect your identity. With most VPN providers, you can also appear to be in a completely different country, adding to your disguise.

There are tons of advantages you can look forward to if you decide to use a VPN. Take a look at some of the crucial ones.

Benefits of using a VPN

When choosing a VPN, you can find both free and paid options. We recommend you go with the paid ones, since they have stronger security, encryption and data protection, as well as more advanced features. Free VPNs come with limitations and risk of malicious attacks on the software itself.

You can choose to buy a singular VPN service or opt for antivirus software that has a VPN built in, for example Bitdefender’s Ultimate Security plan. That depends on what you use your computer for and how much. 

When you pick one, here’s what it can do for you.

1. Access region-specific content

When we said you could change your location, we meant it. Say you’re using a streaming service and a show you desperately want to watch isn’t available in your country. You can use your VPN to make it look like you’re browsing from a country where it’s unlocked.

This option is also convenient for gamers who want to access maps, skins and other in-game items unavailable in their location.

In addition, you can use this powerful feature when you’re traveling to a region where some of your favorite content may not be accessible.

Do keep in mind that you need to read the Terms and Conditions (yeah, we know - who does that?) of your games and services before doing this, since you could end up getting a penalty. It’s also important to remember that there are entire countries that have strict regulations or even bans on VPNs, for example Belarus, Russia and China. So make sure to be very cautious with your VPN use, friends.

2. Browse like no one’s watching

VPNs shield your browsing habits from prying eyes on the web. Those can be malicious hackers or just third-party cookies tracking your every move to later bombard you with targeted ads. For example, Surfshark VPN features a Cookie blocker that blocks all cookie-related pop-ups and lets you browse in peace (and secret). It works even when the VPN is turned off, which is also pretty neat.

In addition, their CleanWeb 2.0 technology makes sure ads and especially malware don’t stand a chance at all, since they’re blocked before they can even load.

The inability of sites to track your browsing means they can’t collect and analyze any of your data. So, your personal information - or your company’s information in case that’s what you’re using your computer for - is entirely hidden and secure.

3. Save money

It’s well-known that the prices of certain items and services vary based on your location, browsing time, age and many other factors. This most commonly goes for airline tickets and hotel stays.

You can use your VPN to avoid high prices and surcharges. Clear all cookies, turn on your VPN and visit an online shopping site to check out their prices. Then compare your findings with the offers you see when your VPN is off, when you spend a long time on the site or have an active account with the company. 

Sometimes this can really help you find the best deals and avoid breaking the bank. But again, check the Terms and Conditions before you purchase something using a VPN.

4. Secure your smart home

The more smart devices you have connected to your network, the more exposed you are to potential cyberattacks. Phones and computers are generally designed to be decently secure even without a VPN or antivirus, but smart home devices leave a lot to be desired in that regard. 

Protecting your home network with a VPN software means all devices connected to it are secure, be it an air purifier or Alexa.

5. Prevent connection slowdown

Your ISP can intentionally slow down your internet speed based on how much data you’ve consumed (data throttling) or your activities online (bandwidth throttling).

But with a VPN, what kind of data you send and receive and how much is entirely hidden. Therefore, if your ISP can’t see you, they can’t control you and they can’t throttle down your speed.   

The bottom line

You can never be too safe online. So definitely think about getting yourself a solid VPN to pump up your privacy and security as much as you can. And if you have any questions or need help choosing the perfect software for you, feel free to reach out to us.

Windows 10 has a Cloud Clipboard feature that allows users to have a list of multiple copied text in place so that they can reuse it. And each time the computer restarts, the Clipboard Data is cleared. However, you can actually do it manually. How? Read on as this post will walk you through how you can turn on or off as well as clear the Clipboard history in Windows 10. This kind of feature is already available in Windows 10 v1903. In the previous versions of Windows, there was no feature to turn off history in the clipboard and users have to use other ways to clear the clipboard history. And now it seems that Microsoft has put an end to this dilemma as it now allows users to clear the clipboard history. To turn on or off or clear the Clipboard history, here are some instructions you need to follow: Step 1: Tap the Win + X keys to open the power menu and select Settings. Step 2: After that, navigate to Settings > System > Clipboard. Step 3: From there, turn off the toggle button under the Clipboard history section. This will turn off the Cloud Clipboard feature. As a result, the default clipboard will hold one last item and will not display the data on the clipboard. Note: When you tap the Win + V keys to invoke the clipboard manager, you will see a prompt that says, “Can’t show history, See all copied items in place, Turn on clipboard history”. You have the option to turn it back on by simply clicking on the available button. Doing so would only hide the existing data and makes sure that no copy of the data is kept.

Conclusion

On the other hand, if you want to clear the clipboard without affecting its history data, you have to make sure to pin the items on the clipboard that you want to stay. After that, click on the three-dotted icon for the menu and click on the “clear all” option. This will delete all the entries but will keep the pinned items on your clipboard.
