What to do if USB tethering is not working

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.

Option 1 – Try to remove the epfwwfp.sys file

You can try to remove the epfwwfp.sys file using Command Prompt. To do so, refer to the following steps:

• Right-click on the Start button and click on Command Prompt (Admin) from the menu to open Command Prompt with admin privileges.
• Next, type the following command and hit Enter to delete the epfwwfp.sys file:

Did you know you can use emoji in file names inside Windows 10? It is no secret that emojis are basically everywhere and Microsoft has seen this and integrated them into Windows itself, so you can name files using emojis or combine them with text. Placing emojis in file names or in the text is extremely easy, all you have to do is press ⊞ WINDOWS + . and the emoji dialog will open from where you can find which emoji you would like to use. And that's it, you just used emoji for the file naming.

!!!NOTE!!!

In theory, some applications may not like these emojis if they don’t support Unicode characters. However, modern applications are designed to work with a broad set of languages that should properly support emojis. For example, the classic Windows Command Prompt can’t see emoji characters in file names properly, but both PowerShell and Microsoft’s new Windows Terminal can display them properly. If you do run into a problem, you can always open File Explorer and rename the affected files and folders to remove the emoji characters. You can then use those files in applications that don’t properly support emoji file names.

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.

Often when we connect to the internet were browsing indexed pages through some well-known search engine, usually Google. But beneath the so-called normal internet lurks deep and dark web. You might have heard of the deep web and dark web if you have some geeky friends and we are here to explain what exactly is the deep and dark web. The first thing to know is that the deep and dark web is not the same thing and they coexist separately from one another, you could say that beneath the deep web lies the dark web, yet another layer of the internet. So let us explore first the deep web. What is exactly a deep web?

Deep web, hidden web, or invisible web

as sometimes referenced are part of worldwide web not indexed by search engines, meaning that engines do not basically see and index content of deep web sites. The content of the deep web is hidden behind HTTP forms and includes many very common uses such as webmail, online banking, private or otherwise restricted access social-media pages and profiles, some web forums that require registration for viewing content, and services that users must pay for, and which are protected by paywalls, such as video on demand and some online magazines and newspapers. The content of the deep web can be located and accessed by a direct URL or IP address but may require a password or other security access to get past public website pages. While it is not always possible to directly discover a specific web server's content so that it may be indexed, a site potentially can be accessed indirectly (due to computer vulnerabilities). To discover content on the web, search engines use web crawlers that follow hyperlinks through known protocol virtual port numbers. This technique is ideal for discovering content on the surface web but is often ineffective at finding deep web content. For example, these crawlers do not attempt to find dynamic pages that are the result of database queries due to the indeterminate number of queries that are possible. It has been noted that this can be (partially) overcome by providing links to query results, but this could unintentionally inflate the popularity of a member of the deep web.

Dark WEB

The dark web is the World Wide Web content that exists on darknets: overlay networks that use the Internet but require specific software, configurations, or authorization to access. Through the dark web, private computer networks can communicate and conduct business anonymously without divulging identifying information, such as a user's location. The dark web forms a small part of the deep web, the part of the Web not indexed by web search engines, although sometimes the term deep web is mistakenly used to refer specifically to the dark web. The darknets which constitute the dark web include small, friend-to-friend peer-to-peer networks, as well as large, popular networks such as Tor, Freenet, I2P, and Riffle operated by public organizations and individuals. Users of the dark web refer to the regular web as Clearnet due to its unencrypted nature. The Tor dark web or Onionland uses the traffic anonymization technique of onion routing under the network's top-level domain suffix .onion.

Dark & Deep WEB difference

The dark web has often been conflated with the deep web, the parts of the web not indexed (searchable) by search engines. The dark web forms a small part of the deep web but requires custom software in order to access its content. This confusion dates back to at least 2009. Since then, especially in reporting on Silk Road, the two terms have often been conflated, despite recommendations that they should be distinguished. Darknet websites are accessible only through networks such as Tor ("The Onion Routing" project) and I2P ("Invisible Internet Project"). Tor browser and Tor-accessible sites are widely used among darknet users and can be identified by the domain ".onion". While Tor focuses on providing anonymous access to the Internet, I2P specializes in allowing anonymous hosting of websites. Identities and locations of darknet users stay anonymous and cannot be tracked due to the layered encryption system. The darknet encryption technology routes users' data through a large number of intermediate servers, which protects the users' identity and guarantees anonymity. The transmitted information can be decrypted only by a subsequent node in the scheme, which leads to the exit node. The complicated system makes it almost impossible to reproduce the node path and decrypt the information layer by layer. Due to the high level of encryption, websites are not able to track the geolocation and IP of their users, and users are not able to get this information about the host. Thus, communication between darknet users is highly encrypted allowing users to talk, blog, and share files confidentially.

Darknet

The darknet is also used for illegal activity such as illegal trade, forums, and media exchange for pedophiles and terrorists. At the same time, traditional websites have created alternative accessibility for the Tor browser in an effort to connect with their users. ProPublica, for example, launched a new version of its website available exclusively to Tor users.

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.
