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.

Why is Microsoft this rich and respected after this? Most overrated company possibly ever.

"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

2 Windows ME

Pure garbage of an OS. Attempting to Install this operating system typically results in endless blue screens, and cursing. Think a Windows 10 reboot loop is bad due to a forced bad driver update? Windows 8 with it's radical new user interface? Those don't even hold a candle to all the hidden surprises in Windows ME. If you are a lucky one to actually get this OS to install expect it to crash rather often. Many device drivers were unstable, and closing applications would leave quite a bit of garbage in the system ram slowing it down even further due to the OS not being capable of managing memory properly. Even if you do get somewhat decent drivers this OS has so many flaws that even Microsoft threw it under a rug as fast as possible with Windows XP. They could not fix it. I bet even their development team for this ran into issues during beta testing. Have this OS on a work computer back in the day? Step away to grab a cup of coffee only to return to a crashed OS with all your saved ...more

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

3 Windows Vista

It's so unstable

Gross - Fat_Turtle_Gamez

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!

A lot of people hate Windows 8 because it looks different. Windows Vista actually had stability and loading issues. You needed a really good computer to be able to play games on it and especially for something that had been in development for years, it came out a mess. - 3DG20

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.

This sucks! can't even get the google drive offline extension!

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.

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.

5 Windows RT

Windows 8 is better

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

i agree - DominiusDarkKnight5

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

6 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.

It's alright, it is a little faster. But it still takes forever to log on and the horrible new start menu is there! - ShaunFan04

7 Windows 10

It is a fxxking and the worst OS that I use Windows before. Every day keeps update something in the background. Although I stop it in group policy, setup bandwidth limitation and change it in the registry. It will update automatically after Windows reboot. My PC is working good in Windows 7 and Windows 10 2015... before. Now it becomes slow and slow once Windows update is active.

Despise it. Slow and buggy. Buying a second Mac for the home office so never have to use a PC again.

Windows 10 is so slow and I used to get random BSODs for no reason with Windows 10. Windows 10 is probably malware.

Fast,but no control.

Counter intuitive Gui. Lacks user friendliness.

Edit: No longer getting a Mac. Windows is better.

Seriously, OSX is user-friendly and fast. Not to moan about haters but I am getting a Mac in 2019, I'm looking forward to find it's operating system.

So complicated to do basic tasks
So not WYSIWYG. It seems like it but it is not. I much prefer windows over MacOS Mojave.

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.

10 Apartheid Linux Apartheid Linux

Racism! - BorisRule

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

The Contenders

11 iOS

There's stupid Android users pointlessly setting a goal to abandon their beloved Android just like that! There's stupid Xiaomi fans pointlessly setting a goal to abandon their beloved Android UI just like that! Many poor have dreamed for what?
Brands that just exists in their mind! Brands like Xiaomi gave them everything they want. How about those rich who were tired of Samsung and Apple? Waiting to be poor! In order to enjoy what Xiaomi offers, or even enjoy Stock Android. At least iOS can't be altered, gives users a peace of mind, unlike Android that is in the big mess. But I still prefer Android and stay away from Samsung, no matter what happens to me.

This should be number 1! You cannot do anything Apple gracefully give you permission to do. You are only allowed to install programs from their App Store combined with most programs I use everyday not being allowed on the App Store makes it horrific! You also can't perform file management, which I should be able to do with ANY operating system! You also must have MEGA or Dropbox in order to transfer files, and don't forget that you can't manage the files being transferred to your phone! Oh but I can't uninstall it because iPhones must have iOS for calls and texts! It's so bad, there even exists guides to install Android or other operating systems on iPhones! People that say this is secure basically say locking themselves in a house and never coming out is the safe!

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.

Even Incompatible Sharing System is much better than this crap.

12 Red Star OS

Its crap

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


13 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.

14 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.

Slow, slow, slow, very slow in startup especially after login screen, hard disk performance eater, annoying continuous updates with restart enforcement and you have no control over its update

15 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.

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

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.

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.

It's not that bad but Apple could have put the options to put the Classic iOS 6 theme.

21 Lindows

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.

22 Windows 2.0

Not worst OS ever.

23 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

24 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! :(

Hate it worst is ever. Msdos executive r.I.p

25 Ubuntu

The best OS ever!

Said no one ever

Worst os ever crashes! But never used before

Just had it with Ubuntu. I really had some honest and true hope for this distro but I just lost it after installing version 11.10

26 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

27 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.

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?

29 Apple SOS

Worst operating system ever.
I would think of it as ldr4jdrijngrgtkgiugt5jk.

Note: alker33 has an Apple 3

30 openSUSE

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

31 Android OS

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

Playing catchup since started in 2008 (I, along with others, shouldn't have suggested Google to build an os in 99..)

Now affecting (maybe infecting? ) tvs and iot near you..

Illogically, user unfriendly crap. No structure, everything is spread under complete unintuitive, different menus, with no (hovering) tooltips and cutoff descriptions!

Buggy, sluggy, hardware always lags behind the programming. Demands that for best results The GooglePlex knows everything about you down to but not including, your shorts size, who you first kissed, and how many pores you have on your face!

Android Is greatest...

ZTE did a terrible job of making the first Firefox phone, it's just bad

34 Asian OS

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

Me I see the discription

35 JavaOS

Almost no one has heard of the one. JavaOS is, as the name suggests, written in Java. This was in the late nineties, though, so Java was slow. Oh and javaOS was pointless.

36 Windows Whistler

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

I wish I could get my hands on the XP beta... - BorisRule

38 macOS Sierra

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! >:(

Calm down, Its more for the newer macs. If you can upgrade then it doesn't mean its good and fast. - HiN

39 Windows 95

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

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.

40 Tizen OS

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.

This OS isn’t bad, why is this here?

Scripts kiddies, they think that the internet is weak to Kali while in reality, it isn't that good. - 50

Never used. Always underpowered.

Holy crap. I hate this OS. Even I has 8.1 OS that was better than this. Why? I downloaded many games and they worked. I was having roblox. yeah, everything was fine. then I got a FLATOUT 2 disk and I installed on it. then I restarted 8.1 to make the game installed. then BAM. 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.


Are you sure you're using Xubuntu? It doesn't look like you're using one, also are you trying to run exe file on Linux? - 50

49 Windows NT 3.1
50 Windows Home Server

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.
