It is common knowledge that when you open a file that contains viruses, it will automatically infect the operating system. This is why most antivirus programs like Windows Defender won’t allow the opening of a file or execution of any associated program if they detected that the file or program could potentially harm the computer. In situations like this, you may get an error stating, “Operation did not complete successfully because the file contains a virus”. In addition, it is also possible that this error message can pop up even for known programs. To open the program or file that triggered the error, you will be given a couple of options in this post but make sure that the program or file is really safe to open and does not contain any virus. You can open the file or execute the program by disabling the Windows Defender or any antivirus program temporarily. You could also try to add an exclusion in your antivirus program or repair File Explorer or run the Disk Cleanup tool. For more details, refer to each one of the options provided below.

Option 1 – Try to temporarily disable the Windows Defender program

Although you could encounter this error with any antivirus program, it is more common in Windows Defender. Thus, you can try to disable it for a while when you open the file or execute the program. To do so, follow these steps:

• First, click on the Start button and go to Settings > Update and Security > Windows Security.
• Here, select the “Open Windows Security” option located in the right pane.
• After that, click on the “Virus and threat protection” option.

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 Windows Update Error 0xC1900209? Before you can install any updates on your Windows 10 computer, there are a lot of conditions that have to be fulfilled and one of these conditions is software compatibility. It is one of the important factors in installing Windows Updates. So if one of the software in your computer is not compatible with the new Windows Update for your OS, then the Windows 10 setup will not proceed and will block the installation of the new update. This both applies to the cumulative updates and feature updates. In such cases, you will get the following error message when you run Windows Update:

“0xC1900209, Incompatible software is blocking the upgrade process. Uninstall the application and try the upgrade again.”

This error message comes under the umbrella of the Windows 10 pre-upgrade validation using Setup.exe. And for you to identify the incompatible app, you need to grab a Windows 10 install image using the Windows Media Creation tool to download the suitable Windows 10 version and mount it. After that, execute the setup.exe file that’s located in the root folder of the Windows 10 install image. Once you execute the setup file, the upgrade wizard will give you a list of incompatible apps. Once you have determined which software is not compatible with the Windows Update, there are two options you can try to resolve the Windows Update error 0xC1900209 – you can either try to update the conflicting software or uninstall it. For more details, follow the given options below.

When you encounter an error message that says, Chassis Intruded…Fatal Error…System Halted on your monitor then it indicates that the Chassis or the cabinet that holds the CPU, GPU, motherboard, and many more is open. It is a security feature offered by OEMs wherein a connector that is found in the motherboard can detect if the chassis component has been replaced or removed. There are a few OEMs that offer onboard speaker or PC chassis speaker which goes off in this kind of situation. Obviously, the problem has something to do with the hardware and in most cases, you have to put the jumper back on the motherboard with the pin-labeled chassis signal and ground. There are times when some OEMs offer a simple switch that is armed automatically when you properly close the chassis. Thus, you need to check if this switch has something to do with the error. If there is no switch or if it doesn’t resolve the issue, although you may be able to get into Windows with a warm boot, the normal Windows boot won’t really work unless you fix the problem. It is rather false positive and has something to do with the RTC RAM state or the BIOS. You might need to completely disable the Chassis intrusion feature to fix the error. Refer to the suggestions given below to try and fix the “Chassis Intruded, Fatal Error … System Halted” error.

Option 1 – Try to clear CMOS

You can easily clear CMOS by shorting two pins which can be found side by side on the motherboard. Keep in mind that it may vary from OEM to OEM although the basics are still the same to clear CMOS. In addition, you might also have to download the manual from the OEM’s website so that you’ll know its exact location.

Option 2 – Try booting into the BIOS

You can also try booting into the BIOS. All you have to do is tap either the DEL or F2 keys to get there. Note that everything will be set back to their default setting after you reset the CMOS.

Option 3 – Try disabling Chassis intrusion

In this option, you have to look for the Chassis intrusion feature in your BIOS. It might be located under security. From there, disable it and check if the problem’s fixed.

Option 4 – Try to reconfigure the BIOS

Once you have disabled the Chassis feature, you need to reconfigure the BIOS the way you expect it to be or to what it was before the reset.

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.

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.
