A Quick Guide to Fixing Error 451

KMODE_EXCEPTION_NOT_HANDLED seems to be connected primarily to a third-party driver, e1d65x64.sys associated with the Intel(R) Gigabit adapter, NIC/Wired network NDIS (Network Driver Interface Specification) 6.x driver. Error is known to produce the dreaded blue screen of death or BSOD. Most usually error is connected with gaming on Windows 10 computer and it manifests itself during gaming sessions. If you are unlucky and you are faced with this unfortunate error we will be happy to try to help you and present with tips and tricks in order for you to find a solution for it. Before you proceed with the provided solutions, be sure you have sufficient disk space on the Windows drive, run Disk Cleanup and then run CHKDSK.

1) Run the Blue Screen Online Troubleshooter

Open Control Panel, change the view setting to icons. Click Troubleshooting, and click “View all” in the tasks pane. Click “Blue Screen”. This opens the Blue Screen Troubleshooter.

2) Run Driver Verifier

1. Start a Command Prompt window by selecting Run as an administrator, and type verifier to open Driver Verifier Manager.
2. Select Create standard settings (the default task), and select Next. You can also choose to Create custom settings to select from predefined settings, or to select individual options. For more information, see Driver Verifier options and rule classes and Selecting Driver Verifier Options.
3. Under Select what drivers to verify, choose one of the selection schemes described in the following table.

   Driver verifier table:

   Option	Recommended use
   Automatically select unsigned drivers	Useful for testing on computers that are running versions of Windows that do not require signed drivers.
   Automatically select drivers built for older versions of Windows	Useful for testing driver compatibility with newer versions of Windows.
   Automatically select all drivers installed on this computer	Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system. This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance.
   Select driver names from a list	In most cases, you will want to specify which drivers to test. Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance because an I/O request packet (IRP) is passed between each of the drivers in the stack, which allows for a greater level of detail to be provided when an error is detected. Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues (such as deadlocks or mutexes). The Special Pool and I/O Verification options are more effective when used on one driver at a time.

4. If you chose Select driver names from a list, select Next, and then select one or more specific drivers.
5. Select Finish, and then restart the computer.

3) Update network device drivers

Go to the official Intel website and try to find newer versions of drivers, if there are none perhaps you will need to revert back to the previous version.

4) Scan memory for issues

Run a memory test on your system, sometimes these errors can be traced back to a faulty RAM bank.

5) Stop over-clocking your PC

If you have overclocked your PC please reverse it back to its original state and see if that would solve the issue

6) Perform System Restore to the previous restore point

If none of the previous solutions have bared fruit, roll back to a previous restore point and that should solve the issue.

About Potentially Unwanted Applications

Have you ever discovered an unwanted program running on your computer system and wondered how the heck it got there? These unwanted programs, which are referred to as Potentially Unwanted Programs, or PUP briefly, typically tag along as a software package when downloading the program and could cause serious problems for computer users. The term PUP was actually coined to identify this downloadable crapware as something other than malicious software. The primary reason for this is the fact that the majority of PUPs get into users’ computers not because they exploit security weaknesses, for instance, but mainly because the users grant consent to install it – unwittingly in many instances. However, it is obvious that PUPs continue to be bad news for PC users as they could be really detrimental to your computer in numerous ways.

How does unwanted software affect you?

PUPs come in various forms; having said that, many are classified as adware, which always displays irritating ads and advertising banners on internet pages that you’re exploring. Additionally, they come in the form of web browser extension add-ons and toolbars. Not only they entirely fill up space on your computer screen, but toolbars could also manipulate search engine results, monitor your web browsing activities, decrease your web browser’s efficiency, and slow down your web connection to a crawl. PUPs load up a nasty bite if left unchecked. Some PUPs carry keyloggers, dialers, and other software to gather your personal details which might lead to identity theft. Often, such software will turn off security protections and settings to take control over your computer, making that computer susceptible to online hackers and data thieves. At a minimum, PUPs slow your PC down with every added program.

Preventing unwanted programs

• When installing anything on your desktop, always study the fine print, including the EULA. Don’t accept terms of use that are for bundled programs. • Choose the “custom” install whenever installing an application. In particular, focus on those tiny boxes that have been checked as default, where you may ‘agree’ to get advertisements or install software bundlers. • Use an advert blocker/pop-up blocker; Deploy anti-malware products such as Safebytes Anti-malware. These software programs will establish a wall between your computer and cybercriminals. • Avoid installing applications you don’t really need. Do not ever install software programs that appear suspicious or malicious. • Don’t download programs from popups, internet advertising, file sharing sites, and also other unreliable sources; be cautious about any preset, unwanted options when downloading software. Avoid going to weblogs and sites that promote pirated software.

Regular and gaming headphones have many differences between them and not knowing what they are can lead you to get yourself the wrong one. In this article, our goal is to analyze the differences between them so you can choose the right one for you.

Price

One thing that goes in both worlds is that the cheapest models on both sides are not really worth the purchase since both the quality and longevity will be very low. If we compare high-end models, regular headphones are far far more expensive than gaming ones. Hi-end gaming models can go as far as 400$, perhaps a little more but hi-end audio regular headphones are going even for over 2000$.

If we compare same-price headphones generally regular ones will offer you a little better sound quality but gaming headphones will offer some features such as positional audio that regular ones do not have.

Surround sound and positional audio

One of the main advantages of gaming headsets is positional audio and true surround sound. this technology is built-in so you can hear more clearly where your enemy is coming from that is a big help in competitive games. This is achieved by positioning multiple speakers in various positions and angles inside them. Each speaker has a different sound channel that is mixed with another speaker in order to provide you with a full surround experience.

Regular headphones have typically one or two speakers on both sides aimed at the same angle and can not offer precise surround or positional audio.

Noise cancellation

Both gaming and hi-fi headphones offer some sort of noise cancelation to minimize outside noise but if you really want to focus and have good noise cancelation you will have to look out for headphones with active noise cancelation or ANC.

Microphone quality

Let us say this right at the start, most middle and quality regular audio headphones do not have a microphone at all, and ones that might pack one usually have it at a lower quality than gaming ones. This of course makes perfect sense since regular headphones will focus on audio, and gaming ones will focus on playing games where having a good microphone is essential in order to game properly.

Speaker and sound quality

Speaker quality will reflect directly on the sound quality and fidelity. This is where audio regular headphones have an advantage over gaming ones. Since they do not have many small speakers positioned at various angled and instead have just a few, usually 2 or 1 large one, that one is of much better quality and range for audio than a pack of small ones. If you are searching for clarity and quality of the audio itself, especially if you are listening to some FLAC uncompressed music, then regular HiFi ones are a much better choice.

Longevity and durability

Another area where regular ones have an advantage but that is no surprise since their price goes far up compared to gaming ones. Most of the time everything in hi-end audio headphones is made from quality materials and designed to last a long time and therefore advantage. Most of the time gaming headphones will come in plastic versions whereas higher quality audio ones pack a lot of durable metal in frames and in buds making them much more durable. Of course, we are talking here about proper headphone use, not extreme cases of throwing, etc.

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.

• If a User Account Control or UAC prompt appears, click on Yes.
• Next, type in the following command to see the list of the available features.

DISM /online /get-features /format:table | more

• Now all you have to do is copy the name of the feature that you want to enable and for you to do that, you need to execute the following command:

DISM /online /enable-feature /featurename:[Enter the name of the feature here] –All

Note: Now if you want to disable a feature that’s already enabled in your computer, refer to these sub-steps:

• First, you need to check what features are enabled, and for you to find out, enter this command: DISM /online /get-features /format:table | find “Enabled" | more
• And if you want to check the detailed information about a particular feature, you can enter this command: DISM /online /get-featureinfo/featurename:[Enter the name of the feature here]

Option 3 – via Windows Powershell

As you know, the Windows Powershell is a very important tool in Windows 10, and a powerful one at that since you can do a lot of things using this command line. So while you use this tool you need to populate the list of available features first and then you have to download the feature your desired feature.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Next, type in the following command to populate the list of available features:

Get-WindowsOptionalFeature –Online

• After that, enter the following command to install any feature you want to enable from the list of available features:

Get-WindowsOptionalFeature -Online -FeatureName *Type feature name*

• Now enter the following command to enable your desired feature:

Enable-WindowsOptionalFeature -Online -FeatureName “Type feature name” –all

• And if you want to disable any enabled feature, just enter the following command:

Disable-WindowsOptionalFeature -Online -FeatureName “Type feature name”

Option 4 – via an external installation source

You also have the option to fetch the latest features from an updated offline source. The source could be an ISO any other type of image or just a folder. So you need to decide if you want to use Windows Powershell or Command Prompt.

• If you want to use Command Prompt, just enter this command: exe /online /enable-feature /featurename:< /All /Source:<Enter the path of the feature here>
• If you want to use Windows Powershell, use this command: Install-WindowsFeature –Source “<Enter the path of the feature here>”

Note: If you want to get the latest features, you need to get the latest version of the image of the operating system that you are trying to install the feature from.
