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.

Recently, a few users reported that they were unable to turn on their computers for some reason and at the same time their computers Computer makes a beeping noise couple of times or continuously whenever they try to turn them on. The sounds the computers are making can be quite annoying and it also signifies that there is something wrong with them. The problem might have something to do with the hardware inside of the computer system rather than Windows 10 itself. As you know, a computer is designed to deliver audible error sounds every time some part of the hardware is not properly working. For instance, if you hear a single beep, this indicates that your GPU is having some issues and if you’re hearing two beeps, it indicates that your RAM is not working properly, whereas three beeps that repeat after a pause when you turn on your computer means that there is something wrong with the system memory. On the other hand, if your computer is beeping continuously, this means that the problem lies with the processor. To fix this issue, here are some suggestions that might help but before you proceed, make sure that you know how to manage your computer’s hardware, if not, better have some expert do it for you.

Option 1 – Try checking the RAM

One of the basic things you can do in this kind of case is to check the RAM. Prepare some screwdrivers and dig into your PC and then look for the RAM slots and ensure that they are attached firmly. There are times when moving around your computer daily can cause certain components in your computer to become loose. Worst case scenario is that the RAM might be broken so really have to replace it.

Option 2 – Try checking the graphics card

After digging into your computer, check the graphics card and give it some good cleaning. As you know, you have to remove certain components like the graphics card regularly and clean them to help increase their lifespan and avoid errors in a startup. And if it turns out that the graphics card is broken, you have to replace it with a new one to fix the problem.

Option 3 – Try checking the processor

The processor is the brain of every computer so if it ends up not working, everything else is useless. Thus, you need to check it to see if it’s firmly attached and see if it needs some cleaning of dust and other debris. After that, try turning on your computer again. If it doesn’t work, then you might have to take your system to a technician to resolve the problem for you.

What is RTX

Nvidia GeForce RTX is a high-end professional visual computing platform created by Nvidia, primarily used for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production. Nvidia RTX enables real-time ray tracing. Historically, ray tracing had been reserved for non-real-time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows, and reflections. RTX runs on Nvidia Volta-, Turing- and Ampere-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration.

Advantage in games

With incredible lighting and shadows, reflection, better smoke, and water effects, and more, RTX has managed to place awesome real-time effects on your desktop all that’s to Nvidia technology behind it. Of course, in order to harvest this kind of technology and features game itself needs to support and have RTX in it, you can not turn RTX in just any game, the game itself must have technology build in it. Therefore we are bringing you the list of all RTX games you can find currently on the market so you can enjoy at the moment best graphics a PC can offer

Steam is one of if not the largest online store for the digital distribution of games on the PC platform. The game gets downloaded to your PC when you are planning to play it and its saves are synched in the Steam cloud. They get automatically downloaded when you install the game but you can also get your saves by directly downloading them from Valve's website in your browser. If Steam isn’t automatically downloading your old save games after you install a game, ensure Steam Cloud is enabled for that game within Steam. Locate the game in your Steam library, right-click it, and then select Properties. Click the Updates tab and ensure the Enable Steam Cloud synchronization option is checked for the game. If this option isn’t checked, Steam won’t automatically download your cloud saves. If you don’t see a Steam Cloud option for a game here, that game doesn’t support Steam Cloud. Not all games on Steam do, it’s up to each game developer.

Download the Files in Your Web Browser

Valve lets you download your Steam cloud save files via a web browser, too. You can download just your saved files without re-downloading the entire game. To find your saved files, visit Valve’s View Steam Cloud page in your web browser and sign in with your Steam account. You’ll see a list of games using your Steam Cloud storage. Locate the game in the list and click Show Files to see all the files for a game. Each game has a page showing all the files it’s storing in Steam Cloud, as well as the date they were modified. To download a file, click Download. Download all the save files for your game, and you’ll have a copy of its save games. This feature is especially useful for multi-platform games that don’t automatically synchronize save files between platforms.

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.

How to Fix Error Code 22

Error Code 22 - What is it?

Code 22 is a type of Device Manager Error code. Device manager errors are reported by the drivers causing the problem. It indicates that the devices are disabled in the Device Manager. This error code is displayed in the following format:
