Building your skill set could be a very important thing, especially in today’s world, and what’s the best way other than online learning classes. You are not exposing yourself to pandemics, staying safe in the warmth of your home and most of the courses are free.
Presented here are sites that I believe will and can help you with your goal of learning desired material whatever that might be. Sites are listed in no particular order with a description of what each has to offer.
Coursera was one of the pioneers when it comes to college education online. When it started all courses were free and offered certificates if the taker has done tasks with a passing grade. Today not everything is free but still, there are tons of free courses that can help you to learn something new and to advance in your work or hobby.
Google is using the Coursera platform to deliver its courses to the audience and besides google a lot of academic professors from Princeton, Stanford, John Hopkins and many more are presently offering their course material.
edX has evolved from MITx, MIT’s free initiative to place some free academic lectures from its classrooms free into the world. Since it was rebranded into edX it started including other big university names like Berkeley, University of Texas System, Harvard, and many more.
Since its infant days, edX has expanded and included many areas that it offers coursework from arts to science. Certificated today are mostly not free but course videos are, so if you care to learn and not wave certificates around this is a great place to do it.
Udemy has a little different approach to course material than previously mentioned websites. Teachers on Udemy are mostly people that are working in a given field. Programmers will teach programming, fitness instructors will teach training, etc.
There are vas variety of topics even on lifestyle, hobbies even gaming to more serious ones like software developing hardware, etc.
There are free courses but mostly are one-time purchases with unlimited access to course material and with frequent discounts udemy might be a good place to look if you can find anything interesting.
Alison is kind of Udemy if we are talking about course material and who is teaching, the difference however is that it has more free content and it is one of the rare websites on this list that has Language courses.
Courses vary from beginner level to more advanced ones.
Udacity was also one of the earlier websites to offer free courses, in today’s world it still has free material but there is also paying one.
The big difference from other competitors is that Udacity focuses mostly on programming, data science, and web development and it is very strong in this field. There are no courses about art. Music or similar, mostly IT stuff is covered here.
If this is something that interests you, make a free account and give it a go.
Codecademy is a website mainly focused on teaching you how to code. Pro plan is there but there are a lot of basic and free courses on the mentioned subject.
The curriculum is really wide covering Python, R, Java, JavaScript, SQL, Ruby, C#, C++, Swift, PHP, HTML, CSS and more so I am sure that if you are interested in coding this would be a pretty good place to find things.
Besides pure language coding courses site offers also, Cybersecurity, Web design, Data science, web development, Game Development, Mobile Development, and many more courses on provided subjects.
Academic Earth has been built with one simple premise: Everyone deserves access to education.
Lead by this kind of mindset on Academic Earth you will find well, academic courses similar to ones found on edX and Coursera, but from mentioned sites here all courses are free and you will find only academic ones, there are no entrepreneur or expert courses here, just pure academic ones.
If you wish to see and learn something the way it is taught in Harvard, Berkeley, MIT, etc this is the place for you.
Khan academy is completely free and it is offering courses matching certain grades for children. It is offering courses for all 8 years of elementary school, math courses for high school and college with some coursework on topics like science, arts & humanities, reading, life skills, etc.
Despite not being on the same level as some university courses presented on other mentioned websites Khan Academy is a good place to learn a lot of basic skills that you could build upon later.
I hope that I have helped you in some way to expand your skill set and learn something new with provided sources and I hope to see you again on errortools.com

So, next time when you or your friends encounter this problem, try these quick fixes to repair the error without any hassle. Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.
Error CausesThe CompareExchange128 error normally occurs due to two possible reasons:
One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.
NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.
Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b
This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:
If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:
If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.
If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.
