10 Worst Computer Viruses in history

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

viruses10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent.
Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server.

Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation.
Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught.

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging.
This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses.
As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last.
Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs.
The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter.

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch.
The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries.
The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms.

Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage.
Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red.

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic.
The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note.
The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million.

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack.
Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million.
Other notable viruses

The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years:

Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove.

Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India.

Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably.

Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather.

Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries.

Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.”

Explorezip: This worm used fake emails to spread to every machine on thousands of local networks.

Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million.

Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs.

Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates.

Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

Everything You Need to Know About Disk Partitioning

Disk partitioning is a concept that’s been around for so long, but is still only familiar to few. If done right, it can help get your computer in perfect order. 

Today we bring you a simple definition of disk partitioning, its pros and cons, and a quick tip on how to do it properly to reap its full benefit!

Definition and purpose

The simplest way to define disk partitioning would be: it’s exactly what it sounds like. It means taking a hard disk drive and separating it into different segments. These segments are called partitions. You can visualize it as cutting a cake into smaller pieces - not necessarily of the same size, though. 

So what is the purpose of these pieces?

Well, when you first get a hard drive, it’s basically just a bunch of unallocated storage space. Until there’s at least one partition, this space is unusable to your operating system. Once you create a partition, your OS will recognize it as usable storage space. 

You can choose to create a single partition and use it for all your files, from program files to personal data. A lot of off-the-shelf computers come with one primary partition like this and a small secondary one reserved for recovery purposes. 

Whether or not you want to split your disk into more than one segment is up to you. We would generally recommend it, though. The whole point of partitioning is for each segment to have its own purpose.

So treating all your storage space as a single unit containing different file types would be like constructing an office building with only one massive room for everything - day-to-day work, conferences, interviews, etc. And all of this for different departments of the company. You can see how this might get a little messy.

Creating multiple partitions eliminates the task of running several different types of files from the same place. This takes a heavy load off the entire process of accessing data.

Disk partitioning also brings a ton of other benefits to the table. An important disclaimer, though: there are disadvantages too. We will walk you through both sides to help you get an objective idea and make an informed decision.

What are the benefits of disk partitioning?

1. Better file organization

This is the most obvious and perhaps the biggest advantage of partitioning your hard drive. 

As we already mentioned, partitioning allows you to create separate segments for different file and data types. You wouldn’t want to use the same partition for your system files and for games, would you? 

If organization and time management are important to you, then multiple partitions are the right solution. Searching for specific files will be much easier overall. Say you have one hard drive, but three partitions: C for the system files alone, D for multimedia files and documents, and E for games and apps. Your computer loads the system from C without interference from the other two, and you know exactly where to look when searching for a file.

2. Easy reinstallation

File management isn’t the only thing made faster and simpler thanks to partitioning. If you opt for creating multiple segments on your drive, reinstalling Windows will be easy peasy. 

That’s because all you need to do is format the partition your system is on. Then you reinstall the OS on it, and there you go. Now you have a clean installation, with all your files saved on other partitions intact. You can even make a copy of your system partition, so you can revisit the exact same installation in the future if you want. And the whole time your pictures, music, documents stay exactly where you left them.

3. Possibility of using multiple file systems

By now you’ve understood that partitions function completely separately. This means that, if for some reason you need multiple file system capabilities, partitioning will allow that.

One segment could be used for, say, an NTFS file system, while another could run ext or APFS.

4. Running different OSes

You’re an avid Windows user but need to use Linux on the side? No problem. You don’t need to buy a separate computer or anything. The possibility of running different file systems also means you can use partitioning to run multiple operating systems.

Doesn’t that sound enticing? One machine for multiple totally different uses!

5. Backup and recovery made simple

Data loss can happen on any disk, partitioned or not. However, it’s much easier to get it back on a partitioned one. You know where you stored what, and each partition can be backed up exactly as it is. It’s also a lot faster to back up single partitions than entire hard drives.

Ultimately this also means a faster path to recovery. If you lose or accidentally delete important files and data, you might want to use a recovery tool like Recuva to scan for them and get them back. Recuva is even powerful enough to recover data from damaged hard drives. But no matter how powerful, scanning a whole drive is strenuous for any recovery tool. Scanning independent partitions is a lot more convenient than that, and will get you to your goal more efficiently.

6. Optimized performance

Now, let’s keep in mind that computer performance is influenced by a number of factors. Partitioning alone isn’t what makes it better or worse. However, it can contribute to optimization. It’s easier for your computer to scan, say, a 40 GB partition to fetch the system file it needs than scanning the entire capacity of your drive.

7. Improved security (possibly*)

Separate partitions can help make your system more secure. Firstly, they minimize file corruption. If one partition gets corrupted, the others should remain unaffected. And keeping in mind the previous point about backup and recovery, ‘fixing’ the damaged partition would be much easier than fixing the entire hard drive. 

Partitioning also improves security in terms of malware protection. A malicious attack on one partition is easier to deal with than malware on the whole drive. If your system partition gets infected, you can simply reinstall your OS and that should do the trick.

*Do keep in mind that partitioning can’t defend you against more advanced attacks. So make sure not to give in to a false sense of security.

What are the disadvantages of partitioning?

1. Data is still vulnerable

Yes, it’s easier to back up and recover data from independent partitions. And yes, partitioning may help protect separated files and data to a higher degree. But remember: everything is still on a single physical drive. So while digital errors and issues may be easier to deal with on partitioned drives, physical damage obviously won’t be.

If your hard drive is destroyed in some way, all data on it will be gone. That’s why, if you have crucial files on your PC, it’s important to give them the proper backup treatment before it’s too late.

2. Disbalance of space

Allocating storage space on separate partitions may be a little more tricky than you think. You may fill up one partition a lot faster than another. So on one side you’re struggling with space, and on another you have too much of it to spare. Imagine nearly filling up your system partition and then it turns out you need a lot more space for its updates than you thought.

That’s why you really have to be sure you actually have enough files of different types that you need help managing efficiently. Otherwise you’ll just create a struggle and disbalance in terms of storage.

3. Increased risk of error

If done incorrectly, partitioning can lead to more harm than good. Aside from space disbalance, there is an increased risk of incorrect partition sizes and formatting. Plus, human error is also a factor: in a moment of distraction, you may erase one partition when you meant another. Undoing such mistakes will definitely be tedious and time-consuming.

4. SSDs eliminate the need of partitioning

SSDs (solid-state drives) don’t function in the same way that HDDs do. They have faster read times and can organize files on their own. This quite literally eliminates the need for organization on your part.

Partitioning: yes or no?

The bottom line is that multiple partitions might not be necessary for the average user. But if you’re planning on storing many file types or different file and operating systems on the same PC, then you should give it a shot. It’s also an excellent solution for businesses, of course.

And if our pros and cons list isn’t enough to help you decide, you can always send us a message and we’ll help you make the right choice.

Decided to partition your hard drive?

If you’ve decided to give it a go, you definitely should make sure to do it right. 

The two most effective and reliable ways to partition are using the built-in options on Windows or investing in a dedicated partitioning tool, like the EaseUS Partition Master. Which one you'll opt for depends on your specific needs. 

Option 1 may be more suitable for users with at least some level of experience. In this case, you’d have to know exactly which steps to take without making errors. This is done in Disk Management on Windows 10/11. From there, you can select the partitions you’d like to split into different volumes of selected sizes.

If this is your first time partitioning, we highly suggest you either consult professionals for this or move on to option 2. The EaseUS partitioning software is specifically designed for beginners, with an intuitive interface helping you succeed in the process. All you need to do is pick the Partition Master package tailored to your needs and follow their guide

Each package offers technical support as well, and even free upgrades (to varying degrees based on your subscription). Plus, all of this is valid for not one, but two PCs.

It’s the perfect solution for a smooth and error-free partitioning process. If you want to organize your hard drives efficiently and make the most of all your space without doing irreparable damage, it’s definitely worth the investment.

What to do if Windows Media Player is not playing the Music Playlist in Windows 10
Many users would probably agree that the Windows Media Player, in most cases, is a lot better than the Groove. Although it is understandable why the Groove Music app was created, it may be time for Microsoft to bring its focus back on Windows Media Player. Even more, so that some users are experiencing an issue where they were not able to play their playlist in the Windows Media Player on their Windows 10 PCs. One particular user claimed that when he removed his music from the C drive and transferred them to the C drive for some reason he didn’t state. Right after he did that, any attempts to play songs in the Windows Media Player just don’t seem to work. Transferring music to a different location shouldn’t cause any issue but for some unknown reason, it did. According to security experts, the reason why the Windows Media Player didn’t play the playlist is that it still believes that the songs are still located in the C drive when they’re really not. So the question here is, how can you get the Windows Media Player to recognize the exact and correct location of the songs? Worry not, for this post will show you how exactly you can do that. Carefully follow each one of the instructions given below to fix the Windows Media Player issue.

Option 1 – Try running the WMP Troubleshooters

In case there are any issues with the Windows Media Player, you can always count on the WMP Troubleshooters to fix the problem for you. These built-in troubleshooters, namely, Windows Media Player Library and Windows Media Player DVD Troubleshooters can help you fix the problem, so run them both and see if you can now play those songs or not.

Option 2 – Try rebuilding the Windows Media Player Database

If the first option didn’t work for you, you might have to rebuild the Windows Media Player database. You can do this by following the steps below.
  • Tap the Win + R keys at the same time to open the Run dialog box.
  • After that, copy and paste this command in the field: %userprofile%Local SettingsApplication DataMicrosoftMedia Player
  • Once you’ve pasted the command, hit Enter then you will see a new File Explorer which is the folder for the Media Player. You will have to delete every item in this folder, except for the folders. Meaning to say, you must only delete the individual contents inside but not the folders.
  • Now launch the Windows Media Player again and watch as it rebuilds the music library automatically.

How to remove ConvertDocsOnline from Your PC

ConvertDocsOnline is a Browser Extension for Google Chrome developed by Mindspark Inc. This extension offers users a quick and easy way to convert documents without any additional applications installed on their computer, it also has quick access links to popular websites that the average user might find interesting. While all this may look appealing and nice, this extension injects itself into your browser.

While installed, ConvertDocsOnline will monitor your browsing activity and record visited websites, clicked links, downloads, and even viewed products. All this information is later used/sold to Mindsparks Ad network to better serve user-targeted ads.

Browsing the internet with this extension installed will result in ad placement throughout your browsing sessions. These ads might appear as normal links (sponsored content), ad links, or even pop-up ads.

ConvertDocsOnline has been marked as a Browser Hijacker by several Anti-Virus scanners and is therefore recommended for optional removal from your PC.

About Browser Hijackers

Browser hijackers (sometimes referred to as hijackware) are a type of malware that changes web browser settings without the user’s knowledge or permission. These types of hijacks are increasing at an alarming rate around the globe, and they can be truly nefarious and sometimes dangerous too. There are plenty of reasons why you may have a browser hijack; however commercial, marketing, and advertising are definitely the primary reasons for their creation. In most cases, browser hijacking is used for earning advertising revenue that comes from forced ad mouse clicks and site visits. It might appear naive, but the majority of these sites are not legitimate and may pose a significant threat to your online safety. In a much worst case, your internet browser could be hijacked to download malicious software that can do a lot of damage to your PC.

Symptoms of browser hijacker malware

Symptoms that a web browser is a hi-jacked include: 1. the browser’s homepage is modified 2. your internet browser is constantly being redirected to adult websites 3. the default online search engine and/or the default browser settings are altered 4. you see many toolbars in your internet browser 5. you might find endless pop-up adverts on your computer screen 6. your web browser gets slow, buggy crashes very often 7. you can’t navigate to certain web pages, such as computer security software-related websites.

How they infect computer systems

Browser hijackers can enter a PC in some way or other, for example via downloads, file sharing, and e-mail also. Many browser hijackings come from add-on software, i.e., toolbars, browser helper objects (BHO), or plug-ins added to browsers to give them extra functionality. Browser hijackers sneak to your computer in addition to free software downloads also that you unwittingly install alongside the original. Examples of popular browser hijackers are Fireball, CoolWebSearch. GoSave, Ask Toolbar, RocketTab, and Babylon Toolbar. The existence of any browser hijacker on your computer could drastically diminish the web browsing experience, record your internet activities that lead to critical privacy issues, degrade overall computer efficiency, and result in application instability also.

Removing browser hijackers

Certain hijackers could be removed by simply uninstalling the related freeware or add-ons from the Add or Remove Programs in the Windows control panel. But, many hijacking codes are certainly not very easy to get rid of manually, since they go deeper into your operating system. Beginner PC users should not try for the manual form of removal methods, as it calls for thorough system knowledge to perform fixes on the system registry and HOSTS file. Browser hijackers can be effectively removed by installing and running anti-malware software on the affected PC. To get rid of any browser hijacker from your laptop or computer, you should download this particular certified malware removal application – SafeBytes Anti-Malware. Along with the antivirus tool, a system optimizer, like SafeBytes’s Total System Care, will help you in getting rid of all related files and modifications in the computer registry automatically.

Virus Blocking Access To Safebytes Website And Preventing Anti-Malware Downloads - What You Should Do?

All malware is bad and the level of the damage will vary greatly in accordance with the type of infection. Some malware types modify browser settings by including a proxy server or modify the PC’s DNS configuration settings. In such cases, you’ll be unable to visit some or all of the websites, and thus unable to download or install the necessary security software to remove the malware. If you are reading this now, you may have probably realized that a malware infection is the cause of your blocked net traffic. So how to proceed when you want to install antivirus software such as Safebytes? Do as instructed below to remove malware through alternate ways.

Get rid of viruses in Safe Mode

The Windows operating system includes a special mode known as “Safe Mode” where just the bare minimum required programs and services are loaded. If the malicious software is set to load immediately when PC boots, switching into this particular mode can prevent it from doing so. In order to enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSConfig and look for the “Safe Boot” options under the “Boot” tab. Once you are in safe mode, you can try to download and install your antivirus software application without the hindrance of the malware. Now, you can actually run the antivirus scan to eliminate computer viruses and malware without hindrance from another malicious application.

Switch to an alternate internet browser

Some malware only targets certain internet browsers. If this is your situation, make use of another internet browser as it can circumvent the malware. If you’re not able to download the anti-virus program using Internet Explorer, this means the virus could be targeting IE’s vulnerabilities. Here, you need to switch to a different internet browser like Firefox or Chrome to download the Safebytes Anti-malware program.

Install antivirus on a USB drive

Another option would be to make a portable anti-malware program on your USB stick. Adopt these measures to run the anti-malware on the infected PC. 1) On a clean PC, download and install Safebytes Anti-Malware. 2) Plug the pen drive into the clean PC. 3) Double click on the downloaded file to open the installation wizard. 4) When asked, choose the location of the pen drive as the place where you would like to store the software files. Follow the instructions on the computer screen to finish up the installation process. 5) Now, transfer the thumb drive to the infected PC. 6) Double-click the anti-malware program EXE file on the pen drive. 7) Run Full System Scan to detect and clean-up up all kinds of malware.

A Guide to Fixing Error 101

REvil vanishes over night without trace
REvilREevil is one of the most active and successful hacking groups connected to Russia and operating all over the world. The group recently demanded a huge bitcoin ransom for an attack targeting IT firm Kaseya in the USA. Since Tuesday blog and payment site run by REvil group cannot be longer reached without any kind of explanation or why. The reason behind the disappearance is unknown but has sparked speculation that the group may have been targeted deliberately by authorities. US President Joe Biden said he raised the issue with Vladimir Putin during a phone call on Friday, after discussing the subject during a summit with the Russian president in Geneva last month. Mr. Biden told reporters that he had "made it very clear to him...we expect them to act" on information and also hinted the US could take direct digital retaliation on servers used for intrusions. The timing of Tuesday's outage has sparked speculation that either the US or Russian officials may have taken action against REvil - though officials have so far declined to comment and cyber experts say sudden disappearances of groups are not necessarily uncommon. The development comes after a series of high-profile ransomware attacks which have hit major US businesses this year. The FBI accused REvil - also known as Sodinokibi - of being behind a ransomware attack on the world's largest meat processing company JBS last month.

Install Windows 11 on any computer officially
Windows 11 system requirementsMicrosoft’s initial Windows 11 hardware requirements were not really well received by users and they were not really clearly represented from the start making a lot of potential customers slowly drift away from the hype. It seems that Microsoft has acknowledged this since they have changed their tune about system hardware requirements for the upcoming Windows 11. It seems that Windows 11 will be able to be officially installed on unsupported computers but with a little inconvenience.

What is a catch?

Windows 11 will still have the same hardware requirements and if the PC meets them, that computer will be officially supported, other ones (any that can run Windows 10) that do not meet system requirements can still run Windows 11 but the system will have to be clean installed. So no upgrade option for old computer users, just a clean install. This means of course that you will need to download the ISO image and make a bootable USB in order to install it. Also since you will be doing a clean install do a backup of the hard drive since it will need to be formatted. Also, Microsoft has stated that with unofficially supported PC some driver updates might not be delivered leaving you with either older driver versions or relying on your hardware manufacturer on them. This is still not confirmed by Microsoft, just stated as an option. We will see how it goes.

Conclusion

It is very good that Microsoft has reconsidered its system requirements and will not stubbornly push its initiatives over the top requirements allowing even older computers to install new OS. I am sure over time lot of users will upgrade their hardware and drive into officially supported waters, but it is good that they will be able to use new OS on their current hardware.

Potential issues with DRM and Alder Lake
We are all waiting for the release of Intel’s Alder Lake series of processors and real-world results on its performance. Sadly lately it came to our attention that some games might have issues with the processor. alder lake cpuNow before you go on the bandwagon on bashing Intel itself take note that it is not Intel’s fault at all. The issue that arises is mostly due to DRM software and how it works. As you might know or not, Alder Lake has two sets of cores, standard performance cores, and power cores, and with Intel’s Thread Director on-chip right cores will be used for the right tasks, and here lies the issue. DRM software might detect Thread Director as something suspicious and malicious, and then cut access to the game because of this. Intel, of course, has reached DRM manufacturers and places documentation about how software should be developed with this hybrid technology in mind. Of course, newer games will be updated if needed and everything will work fine, also games on GOG will work fine because of GOG’s policy of no DRM store but some older ones might be left in limbo. They could work fine but DRM might be triggered and prevent them from loading, usually, game developer itself removes DRM protection after some time but that is not really always the case and there is a chance that some games might simply just not work on Alder Lake CPU only because of DRM protection.

Conclusion

I will admit that I have not been a great fan of DRM in general, I understand that game developer want to protect themselves from piracy but how it looks they were not really successful with it. Even today single-player games get pirated on the day they are released and legally bought ones always make trouble for people that actually paid for them. I remember times when DRM was awful and you could install a game a limited number of times, luckily this was removed but it seems that many old habits still remain sadly and DRM is present even today in various forms. GOG is proof that people will buy DRM-free games and that they will support this kind of model. Maybe it is time to forget about fighting against piracy, you will not make it go away and people who do not want to buy games will not buy them, on other hand many users that do buy games, if they cannot use them they will rest to pirated version since that one will work. It is sad to see that pirated software can work better than a legal one and offer a more pleasant experience.
