Fix Netwtw04.sys BSOD Error in Windows 10

In today's IT world, if you want a computer for typical day-to-day actions and gaming, there are 3 primary ways you can go. An Apple computer with its proprietary hardware and operating system or a typical machine with Windows or Linux operating system.

Each system has both advantages and disadvantages and picking the right one might be difficult for some users. From hardware differences to specific software and operating system, each system is aimed at a different type of work, and in this article, we will explore each one and help you in choosing the right one for you.

Apple ecosystem

Apple has managed to create a unique ecosystem of its own devices, from its iMac desktop computers to more professional MAC studio and power MAC and all the way to tablet iPad and iPhone are powered by Apple's own operating system that connects all of these devices into one large system. So if you really need one singular ecosystem this is a huge advantage.

The ecosystem on the side, MAC computer systems are great, some would argue best for coding, design, video work, and sound editing. MAC M2 chip is optimized for all of these tasks and a specially tailored operating system is just the icing on the cake. Specific Apple-made software like a logic pro or final cut also helps a lot to position MAC systems on top of the line.

Reading all of this you might think hey this is the computer for me, it does everything! Sadly the truth is not like that. The first thing that is difficult on MAC systems and a maybe big reason that it is not so adopted outside professional working environment is lack of games. If you are a gamer or plan on using MAC for gaming, well I have some bad news. The second big turn-off is that MAC systems tend to be more expensive than PC systems, yes components are of higher quality but rest assured that you will pay for also for branding.

Get MAC as your workstation for serious work and for good tech support, if you need a plain home computer keep reading.

Windows PC machine

There is no better feeling than assembling your own computer, tweaking hardware to make a monster and despite haters hating, Windows is the best all-around operating system on the market. It is supporting the largest variety of hardware and the largest variety of software.

The best platform for serious gaming and streaming Windows machine has cemented itself as a multimedia powerhouse. But, this kind of computer is not alien to being also a professional machine, you can practically do everything that you can do on Apple or Linux machine inside Windows, yes some things might require extra steps or will be slightly slower but in the end, being able to do anything is the greatest strength of Windows machine.

Of course, every system has its flaws and Windows is not immune to that. One of the biggest is being the operating system for every hardware ever made and every software as well while keeping legacy support for old software and hardware, basically, its biggest strength is in the same time its biggest weakness leading to sometimes stability issues. Also being able to place any kind of hardware can also lead to the same stability issues. Executing something a little slower than other systems and having some extra steps can also be looked upon as weaknesses.

Linux system

First and perhaps for some people, the biggest advantage of the Linux operating system is its price, it is completely free! Other advantages include the great server and networking included in the OS itself, the large amount of customization, and unmatched stability. The ability to write scripts inside the OS terminal is also a great thing and coding is much more streamlined and friendlier than on other machines.

The power of Linux is the ability to change anything, even on the system layer, no other operating system will let you change the basic functionality of the OS itself while Linux will let you do this. It is also the only operating system you can fully use by booting it up from a USB stick and having the same experience as it was installed on a local hard drive. Among other OS mentioned earlier, Linux is by far the lightest one, taking the smallest amount of memory among the three.

The bad side of the Linux machine is the steep learning curve, among the three mentioned operating systems rest assured Linux is the most difficult to learn and be comfortable in it. The operating system will require you to know the hardware and how computers work in order to fully use its potential. Other things that place it behind are not so wide hardware support compared to Windows and the somewhat confusing distro model.

Linux versions come in form of different distro packages and first-time users will face many of them being left in awe of which one to choose. Also installing drivers and software via a package system can also be a tedious task as well, often being that some version of the driver will not work on the newer version of the Linux distro.

Get a Linux machine if you are well versed in computer technology, if you want great customization of the OS itself or if you do not want to spend money on OS and software since almost entire Linux software is open source.

Error Code 0xC004C020 (Code 0xC004C020) – What is it?

Error code 0xC004C020 (Code 0xC004C020) is an error that occurs when you attempt to activate a copy of Windows 7 with a key, but the key has already been activated multiple times. When receiving this error code, it means that you are trying to exceed the number of times that the Windows 7 key is allowed to be activated. Common symptoms include:

• Attempting to install Windows 7 with a key and a dialog box with the code 0xC004C020 is displayed.
• The computer is unable to install Windows 7 with the key.
• Certain features will refrain from working until the correct key has been entered.

Solution

Error Causes

Error Code 0xC004C020 occurs when you are not able to install Windows 7 using a previously purchased key code that has been installed numerous times previously on the same computer.

• You are not able to use your previously used key to install Windows 7.
• You have used the Windows 7 key the maximum number of times allowed.

Error code 0xC004C020 simply means that the Windows 7 code that you are trying to use to install Windows 7 has already been used the maximum number of times allowed, even when installing it on the same computer that it was previously used on. This would indicate that the key is what is known as a volume key- meaning that there is a cap on the number of uses.

Further Information and Manual Repair

Many people encounter this problem when they are doing software development or testing and need to reinstall Windows 7. Some people might also encounter this error code when installing Windows 7 with a key that was used too many times previously. It should be noted that there are several ways to fix this problem, but if nothing is working, you should contact a computer repair technician.

Method One

Activate by phone- the long method.

1. Click the start button, right-click Computer, click Properties, and then click Activate Windows.  This will open Windows Activation.
2. Click on “Show me other ways to activate”.
3. Find and enter the Windows 7 key, then click Next.
4. Click on “Use the automated phone system”. If you are prompted for an administrator password or a confirmation, confirm or type the password now.
5. Select the location nearest to you and then click the Next button.
6. There will be a list of available phone numbers, choose one and call it. There will be an automated system that will guide the activation process.
7. Enter the installation ID when prompted, it will be listed on your computer screen.
8. The phone system will give you a confirmation ID, write this down.
9. Type this confirmation ID into the space that is provided by step 3. This will be in the activation dialogue. Then, click NEXT and follow the instruction.
10. If this is not successful, stay on the line and be transferred to a customer service representative that will assist you.

Method Two

Activate by phone- this is a much simpler method.

1. Click on Start, type: slui.exe 4 into the Search box
2. Press Enter on the keyboard.
3. Pick your country.
4. Choose the Phone Activation option; stay on hold to speak with a customer service representative.

Method Three

Error code 0xC004C020 occurs if you have used your Windows 7 activation key on multiple computers, or multiple times on the same computer. You are not allowed to exceed the uses of the key—you should consider purchasing a new key if this is the case. A Windows 7 key is available for purchase online through the Microsoft website, in the shop section. The new product key must then be activated within 30 days, or it becomes no longer valid. It can be activated online or through the telephone. If it is not activated on time, features will stop working until the new key has been activated. This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary. 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.

Microsoft has presented its next version of their flagship product, Windows 11, and feelings are divided among users. Some users like it very much and eager to upgrade, some do not like the graphic overhaul it went through, but overall I think Microsoft has done a good job with it. Here in this article, we will discuss some of the new features which Windows brings to the table, well at least ones that were showed, I am sure there are plenty more which we will see once OS has been released.

New Start menu

One of the first things that everyone saw when Microsoft has unveiled Windows 11 is its Start menu. Funny enough this is what has caused most of the divide among users, some find it interesting, and some do not like it. Truth is, it is different, and it is centered in the middle instead of the lower left part of the screen. It has been confirmed however that the Start menu can be moved to any part of the screen so if you want, you could place it on the lower left as it has always been. Live tiles do not longer exist in the Start menu, instead, we have styled simple icons.

Windows 11 Snap controls are great

If you have used the cascade option in previous Windows versions then it is most likely that you will like the new Snap controls. You can quickly snap windows side by side, or arrange them in sections on your desktop just by hovering over maximize button on the title bar.

Windows 11 File Explorer

File explorer has gone through some visual and design changes, the ribbon on top has been completely removed and replaced with a header-like feature with a slick and clean design. The header contains a nice organized and designed single row of icons like cut, paste, copy, rename, delete, and new folder icons.

Settings app ovberhaul

The settings app also has gone through visual and design changes. It has a new design that is very visually appealing and navigation has been simplified and more organized. Finding the right and desired setting is much faster and clearer now.

Widget tab makes comeback in Windows 11

Yes, widgets are back but not like you remember them. Instead of being all-time present at your desktop like once they used to be, now there is a button on the taskbar which brings the widget bar up that contains desired widgets. This way they are easily accessible and do not clutter desktops. So far we have weather, news, calendar, and stocks widget but we will see how development on these goes. I expect to have community-made widgets like in old days for all of our needs.

XBOX app

The new Xbox app is now integrated into Windows 11, offering quick access to Xbox Game Pass games, the social parts of the Xbox network, and the Xbox store.

Security and TPM 2.0 in Windows 11

As widely known by now Windows 11 will require you to have a TPM 2.0 module capable CPU in order to install it. This system requirement has caused a lot of controversies but essentially it seems that MS's goal is to protect your personal data by using this module. The upside of course is that your data will be protected much more than in previous Windows versions, the downside, of course, will be that you will need newer hardware to run OS on it. and that is essentially it, keep on tuned on more Windows 11 information and overall articles tied to PC and technology here at errortools.com

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.

Mozilla Firefox has introduced a new feature known as Restart with Windows which allows the browser to automatically start when your Windows 10 computer boots. This means that if you leave the Firefox browser opened while shutting down your computer, Firefox will re-open automatically along with the tabs that were opened right before you shut down your computer. Although some users may find this feature convenient, there are others who do not approve at all as it could be a nuisance. So if you’re one of the latter, then read on as this post will show you how you can disable the Restart with Windows feature in the Firefox browser on your Windows 10 computer. Refer to the instructions laid out below to get started.

• Step 1: Open Mozilla Firefox and if it’s opened already, just open a new tab and then type the following text in the address bar:

about:config

• Step 2: After typing the text given above, hit Enter and if a prompt with a warning message pops up, simply click on the “I accept the risk!” button to proceed.
• Step 3: Next, type “Restart” in the search filter which should display the following preference in the window:

“toolkit.winRegisterApplicationRestart”

• Step 4: After that, check for the preference value and then see if it’s set to true or not. If it is set to true, then it means that the Restart with Windows feature is enabled so obviously, to disable it, you need to set its value to false.
• Step 5: Now restart your computer without closing Firefox. After restarting your computer, you should no longer see Firefox starting automatically.

The Restart with Windows feature by default is disabled for most users. On the other hand, Mozilla will have this feature enabled as the default configuration in the coming weeks so it’s best that you now know what to do when that time comes since the newer versions of Mozilla Firefox are already being shipped with the Restart with Windows feature. However, if this post did not help you, then you might want to check if the feature has been added to the Startup folder, and from there, you can disable this startup program using the Task Manager > Startup tab.
