Top Ten Worst Operating Systems

The Top Ten

1 Windows 8

Did Microsoft even test this with laptop users? Surely even limited tests with users would have shown that it's unpopular. They've tried to make an OS that is suitable for laptop, tablet and phone an instead created something that is awful for all of them. It beggars belief that a company with so much money is capable of creating something so bad.
To add insult to injury the Microsoft 'how to use windows 8' guides are worse than the product, if that's possible and trying to contact support is a waste of a lot of your time. There is nowhere to get real support or even make a complaint.

But then Microsoft isn't like most companies, as they have a monopoly; If Microsoft didn't have a monopoly, no one would choose their product and they wouldn't exist.

"The Windows 8 UI was designed with tablets in mind." Nevermind all the PC users, they aren't that important. Also firing the whole usability crew (which happened before the release of Windows 7) was an excellent idea. While it worked when the User Interface wasn't really changed (Windows 7), it fell short with sudden UI Changes.

To contrast, the Windows 95 UI was the result of a three year usability research which showed the mouse and having a single Start Button which would open a Start menu was the most intuitive thing, especially when they had to give phone support. With Windows 8, what usability? Some users even complain the Start Screen is confusing to even the Tablet users.

What's worse is when they take say apparent new features ("you can write the name of a program in the start screen to start it" for example) that did already exist in previous versions of Windows, in this case Windows 7. To give minor examples the lies the say to people like that DWM cannot be ...more

Windows 8! The slowest piece I have ever owned! When you're on internet explorer, it's always freezing and having stupid runscript errors, or even crashing sometime, regardless of it's conditions and specs. And don't even get me started on it's lack of ability. You can't download things from the web, or run EXE files! It just gives you message that says "This app can't run on your PC". You can only download stuff from what they call, the Windows store. The windows store is simply the worst app store ever! It's missing thousands of downloadable programs! Even the most common. It even lacks a lot of mobile apps you find in the apple store, or the Google play store. It's even missing the most popular, most common apps like temple run, five nights at Freddy's, Facebook, and subway surf. Instead it only has really lame apps. I have been checking the play store for two years now, and only found 5 good apps so far. And That really sucks. What good is an OS that is constantly ...more

It was too hard to use and it was very slow

2 Windows ME

Why is it every time a new Windows operating system is released, people claim it's the worst ever? Windows 7 until the problems with Windows Installer, Windows Update issues. I do question the timing of these problems Windows 7, does anyone else?. Vista? You have got to be kidding me with that. Vista did not get a fair chance. I bought my new computer with Vista installed - I never had a problem with Vista. Windows ME wins hands down for the worst. I have NEVER had so many problems installing an OS. They should have named it MC Microsoft Crash, that's all the system did. I thought the blue screen was a new feature! (Kidding) Very unstable, there was no fixing it. It was so bad Microsoft should have tracked down every poor soul who purchased that dung. Secret teams should have been dispatched to apologize, giving us double our money back refunds. We should have got XP for free. It was a nightmare, I used to joke with my dad, if he kept bothering me, I would install ME on all of his ...more

All those people voting for Windows 8 or Vista have no clue what they are talking about. Sure they are bad but ME is in a league of its own. The reason why Vista and Windows get more votes is more people tried them. ME was Microsoft's shortest lived OS ever with lifespan of only 1 year. It is the only OS that has not been fixed and had no service packs. Microsoft gave up on this OS as there was no way to fix it. Their official fix was buying XP. Most traces of this OS ever existing has been hidden by Microsoft, it is just that bad.

There's unofficial patches to enable Real DOS mode in ME that improve the operating system. - PerfectImpulseX

I own three legacy machines. One from '98, one from '99, and one from '00. I have tried to install Windows ME on the latter two, and it didn't work at all. Halfway through the installation process they both blue screened, and many hours of messing with BIOS settings and swapping out different parts in the computers did nothing to rectify the problem. It actually managed to install on the first one, but every time I tried to install a program that worked fine on 98 SE, there was some kind of error, not to mention it ran Scandisk every time it booted. 8 and Vista are nasty, but ME is a special kind of terrible. I might as well have been trying to install Mac OSX on those machines.

Should be at the Top..

3 Windows Vista

It crashes all the time, I was using home basic and I have been using it for five years but one day it just said there is a problem and it can't even boot. It told me to remove any newly installed hardware but I didn't even got any hardware installed recently!

Blue screens all the time, run slowly, although it's intel core 2 Duo with 4GB RAM.

Worst operating system put out by Microsoft - slow, freezes up, memory hog, crashes during updates, not worth the money

AFTER ALL THESE YEARS WE HAVE WAITED WE GET A PIECE OF CRAP WITH NO PURPOSE WHATSOEVER! - DominiusDarkKnight5

4 Google Chrome OS

Is nothing but a web browser. Completely lacks any programs other than a calculator the the Chrome Web Browser.
The only programs you can get are web based, which you obtain from the Chrome Web Store, where Google calls them "APPS", and they are far from Andy applications I have seen. However, this OS can be stable and if a web browser is all you need, then I guess Chrome OS is okay for that.

It is the worst os ever. It boots in less than 8 sec. It does not hang, it doesn't get virus. It works out of box. It does not get virus. It updates on its own. There are no drivers to install.

I hate it. It just works and this is very very boring.

Among the worst OSes I have ever used. Everything runs in Chrome, already a terrible browser, and half the time it, doesn't even work right. It's difficult to even do simple things like research projects on Chrome OS. It requires a browser to edit a text document, restricting us to the sad, sad word processors like Word Online, or worse yet, Google Docs. I hate it, I hate it, I hate it. Even Windows Vista (without service packs) is more useful than Chrome OS

THE most overrated operating system. A rip-off. Takes ages to boot, and the only programme you can use is Google Chrome, which isn't even that great. If you want to make an OS where you can't install anything, at least make it cheaper and have some other programmes, for things like chatting, note keeping, even a game. This is tied with Windows 8, and Windows ME.

5 Windows 8.1

Another OS by Microsoft
Microsoft this time promised to add start menu to make this OS user friendly but After downloading the release preview I realized that on clicking the start menu it just opened the same screen of Windows 8. Worst OS from Microsoft. These kind of OS is only meant for tablets, touchscreen devices. I think Microsoft must look forward to enhance the User Interface of Windows 7

Windows 8.1 is only a slight improvement over Windows 8.0... it's still practically unusable for business. Access to information that was one mouse click away in Windows 7.0 is now two or three clicks away. It may open and shut down faster, but there is nothing else fast about working in the Windows 8.1/8 environment. I've used every Microsoft OS since 1984. The best so far have been Windows 7, Windows 2000, Windows NT 3.1 - 4.0 and Windows 98/95. The worst have been Windows 8.1/8, Vista and Windows ME. I am surprised that Vista and Windows 8 have not been franchise killers.

I have been a Windows user since 3.0. I am well grounded in the operating system and have been able to navigate easy until now. They have completely moved things around and made it the most user unfriendly operating system to date. I'm not talking button pushers but power users. I bought a computer for my son and I know struggle to help him resolve problems. I hope this system gets put to rest along side BOB.

Guys it wasnt THAT bad - DominiusDarkKnight5

6 Windows RT

This pile of vomit is worse than anything I've ever used. I used to own a Surface RT, I got it from school when I went there. Holy hell it was a miserable experience. Saying that they already upgraded all their PCs to Windows 8, which sucks, not going to lie, at least I could customise them somewhat. Not with Windows Real Travesty (RT) which was used on earlier models of the Surface before Microsoft abolished it to the fiery pits of hell along with Windows ME, where it belongs.

You can't do anything with Windows RT. Download Google Chrome to replace Internet Crapsplorer? Nope. It ain't happening. Actually you can't download anything from the World Wide Web which is plain awful. You can only download applications from the pathetically small Windows Store on the device. Also the applications aren't tailored for a touch interface. Trying to press those tiny buttons with the finger on Microsoft Word? Torture.

Simply put, Windows RT is a version of Windows 8 which is ...more - Cazaam

Completely useless can't even use adobe has its own PDF reader that has no features RT = really terrible!

This is my first tablets I got as soon as I figured out I couldn't play exe or anything I spelled it for a window 7 tablets that can play exes - Matt92647

7 OSX

Overrated, stupid, the opposite of user friendly (actually apple tries constantly to make it all more difficult for the users), slow and with a lot of problems compared to Linux and Windows 7, over-expensive, did I mentioned slow?.. Wayward like an old man on a bad day... The list could go on forever.

I wished I threw my money in the garbage instead of buying that cancer.

I have no idea what to say, only an idiot would pay $2000 for this os.

Dumb and stupid usability of OSX or MacOS X makes it completely useless. The unix shell could be useful but lacks a proper package manager, everyone had to use a third party package manager like homebrew to install anything, all of which are extremely primitive and not user friendly. The graphical user interface is so stupid that it doesn't even show which applications are open properly, it shows small dots at the end of icons in dock, that does not indicate the number of windows open, so can't switch between windows of the same application. It is utterly confusing to maximize / restore or minimize a window, where does it go. All application files are hidden away, in a maze of dirty file structure with hundreds of wrong directory permissions, for example user doesn't even have full writes in their own home directory by default.

Peple are so stupid:

I NEVER had Any problems with OSX. It just works! I dunno what you guys are doing on it

You don't pay for OSX. You pay for the hardware. I would never use Windows 10 THAT COST MONEY.

Very user friendly and I barely had any viruses. A mix of antiviruses in Windows discovered +10.000 viruses in 5 years (Seriously. Not a joke).

So yeah OSX wins. - HiN

8 Windows 10

Horrible operating system. Very little user control. Updates whenever it wants and crashes what you're doing. Nothing but headaches and problems. Microsoft has sold me on buying a Mac. Windows 7 was good and I can consider it to be far superior to the mess called Windows 10.

I've put up with this pile of manure for way too long, I upgraded from Windows 8 about 3 years ago and it deleted ALL my media software and movie making software! On top of that, it updates without asking and sends data to Microsoft without you knowing. And, speaking of Microsoft, why are they so lazy that they can't release another OS to replace this garbage heap? And the new features are useless. Edge stalks you by keeping track of EVERY SINGLE WEBSITE YOU VISIT. Cortana's worse than Siri. Worse than Google Assistant, even, and you feel like she's spying on you through the webcam. And does Minecraft really have to be built in?

Thanks Windows 10 for introducing me with wonderful Linux. And I appreciate you persistent effort to make something awful and rubbish. Keep up the good work, it will surely benefit Linux to gain even more users.

I wish you could dowgrade from this broken mess.

9 Incompatible Timesharing System

The security is nil. Anyone can hack this operating system, so don't use this. (I know it came out in the late 1960s but I can see a OS that has better security and it came out before this OS) - 50

Is the most unsafety os of all time. Anybody can hack it. If you scare of hacker NEVER use that wastebacket.

This is a pieceb of dog turd! Bad secruity.Anyone can hack this.

Avoid this at ALL COST. It has a lot of offensive stuff in it. I love Linux itself but this one is terrible. - 50

Racism! - BorisRule

The Contenders

11 Blackberry OS

I had a blackberry before and every time I attempted to use this operating system I wanted to chuck it out the window and run it over with a car.

It's the worst mobile operating system. I tried to upgrade to iPhone but my mum won't let me have it. And my dad forced me to have Blackberry so I am stuck with this garbage.

BB STILL THINKS IT CAN PRICE ITS EQUIPMENT HIGH.

BB STILL THINKS THAT YOU PAY TOO MUCH FOR JUST A PHONE!

12 iOS

One of the most stupid products made for stupid people. You need to pay to get your own content stored into your own device. Unless the user is so dumb and stupid and running on father's money, no one should need to do that. There is no use of iOS other than paying apple. And intentionally blocks any third party development to make it useful in anyway. Extreme waste of hardware on an extremely restricted software that doesn't do anything but sending money to apple.

Terrible keyboard, probably the main reason I detest iOS. Apps with no settings. Cross device OS that doesn't take size into consideration. The 12 inch iPad Pro has the same number of words on it as an iPad mini or an iPhone. Absolutely ridiculous. How could Apple be so cheap to not design something functional and relevant for their beautiful devices?

Useless attempt to try to be elitist. It is just a marketing product aimed for the masses to believe they belong to the selected group of exclusive VIP 1% when they are not. Apple hunts for customers who spend all their credit card limit in a Louis Vuitton product and at the same time collect discount coupons for McDonald's

Even Incompatible Sharing System is much better than this crap.

13 Red Star OS

If you think that Windows 10 is the worst OS of all time then you've never heard of North Korea's own Linux distro that blocks stuff that North Korea finds offensive. This really should be #1 because of that. - PerfectImpulseX

Its crap

Y U NO OPEN SOURCE - BorisRule

14 Symbian

Nothing to do here.

It was good back there in 2001-2009, but now...

Never used it, but utter crap.

Symbian was awesome back then, but after Google Mafia start with Stupid Android, Symbian removed...
Symbian was far better than Android, never get hang not crap like android.

15 MS-DOS 4.0

It's a DOS what do you expect?
It wasn't that bad - CerealGuy

If you love text based operating systems and your favorite company is Microsoft, you would use this, I mean why would you use it? It's just a giant command prompt that all the versions of Windows have, Microsoft, please get better by keeping Windows 8 and building off of it.

Biggest pile I've ever seen.

Which one? The European one or the one, after the 3.x release - BorisRule

16 Windows 1.0

This was made before the internet existed, idiots...

Windows 1.0 is NOT an operating system. It runs on DOS.

This is actually an operating environment, not an operating system. Anyway, Windows 1.0 was considered bad even at the time.

It is Windows ONE POINT ZERO, NOT WINDOWS TEN - BorisRule

17 Eeebuntu

That's not an Ubuntu misspell, it is bad, and it is now Aurora.

That is not how you spell ubuntu

Actually linux is better then all the other os's here

18 Windows 2.x

Windows 2.03 is not the worst OS. Also, I have never used it. And, it now includes a maximise, minimise, and close buttons. But it now has task overlapping (like todays versions of Windows) Also, Paint still looks like Windows 1.01, STILL!

Windows 2.x is not an operating system, but rather an operating environment. Same with the other DOS-based versions of Windows that were released before Windows 95.

Without Windows 2 you would still has a 1.0 interface with no multitasking. - njalabi63989

Why Windows 2.03! WHY!

19 IOS 7

Drains battery too fast, and its too bright - Harri666

Really apple? Try again, I get headaches from looking at your interface.

IOS is the worst. You might as well put it second right below windows 8.

9 is worse.IOS 7 is cool.Not as good as android though - pugiscool

Better use Longene - BorisRule

This is what happens if you put win ME and Linux together.It can't run even 1 program designed for Windows.That is why Microsoft brougt them.

Not worst OS ever.

This OS I might think it might only run in Asian languages

Me I see the discription

24 Windows 98 First Edition

Decent, but it has problems.

This one is pretty decent. - CerealGuy

One of the best operating systems out there. Easy to install. Capable of playing everGirl on CD-ROM. - playstationfan66

25 Windows 1.01

1985! 1 year after Apple puts out System 1, Microsoft pulls out Windows 1.x. I am not sure if MS was kinda ify about competing with Windows due to there popularity in MS-DOS (My theory) however if they were trying to compete then WHY! This version although was color unlike Mac, was not very good in design, where you could not overlap Windows, let alone use many at a time, and the graphics were really ugly, and hard to look at for long periods of time. Microsoft has not really changed in how they push something until it becomes something, because the mouse was yet to be widespread, yet the whole system put a lot of emphasis on using a mouse. Along with many performance issues, and a lack of really anything, this systems comes down to one of the worst. - yellowwinner

I would take old windows any day of week.Windows 10 is a joke

Seriously! You guys need to know that it has existed before the introduction of the Internet! :(

27 GNU Hurd

STILL after more than 25 years in development, GNU remains incomplete: Its kernel, Hurd, has never really made it out of the starting blocks. (I'll refer to the complete OS as "GNU Hurd" to avoid confusion with other GNU software.) Almost no one has actually been able to use the OS; it's really more a set of ideas than an operating system. Its still has a webpage saying its in development I ain't gonna wait another 2 century's for a thing that doesn't even exist

28 Linux Linux

HEY! I SEROIUSLY disagree about linux being bad...
Linux by itself isn't even really an OS- there are just linux distros,
Though I can understand why you wouldn't like some of them Ubuntu is a really good distro. You should really try it sometime!

It's highly overrated, utterly confusing to use, it's user hostile, a lot of the software available for it is crap, and, no matter what you do to avoid it, you will have to go through the terminal at least once.

But it's the community that gets the biggest slice of the cake. If you say anything that is even a hint (hint! ) of negative, the community will hate you to the death. They find excuses for this OS (sorry, "kernel") being imperfect.

Plus, everyone in the community has one thing in common: They think that Linux's number one enemy is Windows. They want Linux to be everywhere, yet they fight within their own community.

I know that I'm gonna get a ton of hate for this, but Linux needs to get more user-friendly, and it's community needs to get nicer.

LINUX IS THE BEST

Linux is a KERNEL. and NOT an operating system.

Its asking for a code that Microsoft sent me to my email, and my email doesn't work because AOL messed it up (i have no idea why my family used aol until 2013 but at least the browser was faster than internet explorer) - Harri666

I really like the tiles display. but I don't agree with the menu list vertically which is a stupid thing MS made.

I like tiles display. Also, it works perfectly, without any bugs etc.
Very good OS for cheap money.
I don't know why some people don't like it?

31 openSUSE

Couldn't install properly. *searches online for a solution, none of them works*. - 50

32 Android OS

Android is still the best mobile operating system out there. I've been an Android user since 2008. Viruses? You have to be stupid to think that you actually have a virus on your phone cause an add popped up.
If you don't buy a 50 dollar phone then you will not get any lag. I have to say that Android is much more reliable than Windows Phone.

Literally the worst OS in existence for a multitude of reasons. There is a good reason you pay significantly less for an Android 'smart' (can't really call it that) phone, than for an iPhone. Come on, even Blackberry isn't as bad.

Why the hell Android in this list? - ARandomGuy

Android OS is Google OS or Google Chrome OS as that's where it came from.

Nobody uses it anymore, stop making new versions.

Whistler is a beta. And not just any beta. The XP BETA. So it's almost as good as XP.

WHY ISN’T THIS NUMBER 1? I have a Mac, and every time I upgrade it, to a format of High Sierra, not only does it make the Mac constantly stuck on the progress bar to the point where I have to take it to the Genius Bar to fix it, but it constantly makes my computer run really slow, freezes, and even sometimes crashes! >:(

This OS shaped what Windows look like now. - CerealGuy

Nothing too bad except for crashing issues.

This was horrible. It was basically a layer on top of MS DOS and crashed constantly. When a program misbehaved, it could easily take down the whole computer... and a lot of programs misbehaved.

Stop hating Windows 95! If we didn't have it, we wouldn't have supreme OSs like 2000, 98, XP (with SP2), Vista and 7! THEY ARE MIRACLES! (No, ME, you didn't get invited) - Mii24

It's a worst thing I had been ever used

Well, what do you expect, Tizen OS is a budget operating system and is not a main competitor to operating systems like Android, iOS (Crap OS), and Windows 8 (including RT).

The most bad os I have evrer used. It is because it has very less app in its store. It is better than android in one case that it is linux based os so, it doen,nt get infected by virus.

A problem appeared. then I went to fix it on a place that fixes computers. Then they changed this by this LInux os. I tried to download the games. BUT I can't DOWNLOAD THEM. hate this os. When I downloaded a game: Error. can't download the game.

I've never used it, but it could be all right if you want to pay for a home server.
The standard versions of Windows already allow you to create your own server (and Linux, if you really want to waste time on that). But I guess this makes it easier to do so.
