Error 740 Requested operation requires elevation

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.

In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. Microsoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

More information

The details described leading to speculation that the problem could be related to drivers that Microsoft is providing. On further tests, all Nvme drives that use the Microsoft driver have this problem, but Intel 905P, which has its own driver provided by Intel, is working at full power,”.
