Puppy Linux runs on a potato of any architecture and is super user friendly (grandpa certified)! Only 300 MB or so. https://puppylinux-woof-ce.github.io/
Puppy Linux is made for old machines and generally just works. You can boot it up on a live USB and see what you think. Lots of flavours to choose from.
I recommend arch linux. Also most desktop environment are light enough to run on old hardware. Just disable file content indexing
I'd have to respectfully disagree with you here, as despite arch being a great distro, I wouldn't say that it's very noob-friendly
I've said my peace about distro and desktop environment in another comment, but to answer the piece about what you can do as compared to Windows, Linux can do the vast majority of all your daily tasks. There are a couple of big sticking points, generally.
Microsoft products, i.e. Microsoft Office. There are alternatives available in the Linux space that do a great job and are good enough for probably 95-98% of people, but there are cases where they don't quuiiiite match up. Formatting PowerPoints, for example. You may save a *.pptx from LibreOffice and a colleague will open it in Microsoft PowerPoint and it doesn't look the same at all.
The other major software suite that keeps people in Windows is Adobe. Photoshop? Lightroom? Premiere? Not available on Linux. Again, there are alternatives, but they're never quite as good. I say this as a photographer that runs 100% Linux all the time, I miss my photo editing software! I used Capture One, but the same principle applies. There's no Linux release, and you can't get it running on Linux no matter how much you tinker.
The third biggest sticking point is gaming. You can game on Linux. It's better now than ever. I run AAA brand new releases on my PC, and again I'm 100% Linux. BUT! It does frequently require a little more elbow grease to get working than people are used to, and often times you can never get it to work 100% as well as it would in Windows.
Sorry for the big wall of text. But finally I just want to say, none of this is to dissuade you from putting Linux on those machine. Quite the contrary! I want you to be aware of what the pitfalls may be, so you can look out for them. I'd hate for you to go in expecting everything to be 1:1 with Windows, only for something to not work and it feel like a bad experience in the end.
Almost everything except Ubuntu and SuSe.
I vote Ubuntu, I started as a complete noob about 10 years ago with them and at first it was frustrating and tough, but now everything is just done for me, software updates, sure! I all the sudden want to want a windows-type application, sure! I love that it comes with Firefox, which from what I've read should make your family safer from the initial launch of the browser, no matter where the site they want to reach.
Try mint with Xfce - on 64 bit machines and then go lighter.
alright and are you sure that is the best starter option? also what can i do on linux compared to windows?
Just be warned that your family members will probably have (usually solvable) issues if they want to do anything beyond web browsing. It's a different operating system after all and it works differently in a lot of ways. Definitely recommend looking up some videos about Mint, XFCE, transitioning from Windows to Linux.
best option
Ubuntu is popular and new-user friendly. And xfce is generally lighter on resources. It's a good choice.
What can I do
Almost everything.
Some proprietary apps you've used from windows may not be available, but there equivalent ones would be available on linux.
Stuff like browsing the web(provided that you don't open too many tabs, because you have low ram) and watching movies n all is quite good.
What all things fo you intend to do on it? I think it'll be easier to check that the things you want are there.
For a more "friendly flavored" distro, MX Linux is Debian-based and comes with a bunch of quality of life tools
MX Linux seconded. It's available in 32-bit versions, too.
I haven't used it on a machine with less than 4GB though, but it runs well on an old Dell laptop from 2009.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
