I am a Windows user so plz suggest easy and user-friendly distro. I am a Student and switching mainly due to performance issue. Also I will be dual booting Linux with Windows 11.

Here are my PC specs: Storage : 1 TB Processor: Intel(R) Core(TM) i3-7020U CPU @ 2.30GHz 2.30 GHz (Dual Core) Installed RAM: 4.00 GB (3.87 GB usable) System type: 64-bit operating system, x64-based processor Display Resolution : 1366 x 786 HD+ Display Graphics : Intel UHD 620(2GB internal) Direct X 12

I prefer Ubuntu more than any other distro but am unsure of getting a good deal of performance on my Low-end PC.

So It just depends on you what you want, I can only suggest because your system specs are OK, You can have any type of ubuntu flavour you want, Let me give you a brief Idea

You can find alternatives of ubuntu I.e ubuntu flavours here

Lubuntu

A good Linux distro, If your PC isn't much good in specs then Lubuntu can help you to get maximum performance even from an ultra potato PC, It also offers an OK GUI, It also comes with a handful of apps and stuff, So I guess it would be good for you PC specs,

Xubuntu

Good for performance with very minimal memory usage, This is what is good and recommend for your PC.

It would be good in this case as you are not on a bad PC, It is just normal. Lubuntu is designed for a very minimal thing. But Xubuntu can help you as it is for the average PC and works well even with very good PCs

Kubuntu

Good for a beautiful GUI, It may cut off some performance but is beautiful. But as your specs it will not give much performance, So it's not for heavy use as per your specs but it is good if you are a GUI lover

Ubuntu Vanilla

Good but I don't recommend it for your specs, Don't install it.

I cannot tell you everything all about distros but you need to check out more about them yourself

CONCLUSION

It depends on your admiring, every distribution is good, but I would personally recommend Xubuntu for you.

There are many other distros too, check out Gentoo, mint, kali or Garuda, All these are just the best in their forms

"Every Distribution has its abilities"

Your specs are good enough to use any of them, So go ahead and pick one today.

Arch linux doesn't turn any services on by default, so Arch linux is faster than debian. But as you're a beginner, using a debian distro will be a safe bet, because of the bigger community and stable features. I'll suggest you to use linux mint which is a distro based on ubuntu but has better performance when used in older machines. Research and take precautions about the dual boot, as windows update can cause some problems. And also avoid overwriting and take care of security issues. As you have 1 TB space so the partitions won't bother you I think.
