Electrum 4.2.0 not supporting Windows 7

[NotATether]

However, wouldn't a proper formatting (the slow one, with marking the bad sectors) handle this? Or is the number of bad sectors slowly increasing?

Maybe, I've never tried that.

First of all, why do you use HDD with bad sector to store the OS (and important files)?

It's temporary until I get the logistics to ship more hardware to my area.

1. I have an old cell phone i bought it on 2019. I installed electrum at that time and didn't update it since then (can't tell if the updates was done automatically) and then i left that cell phone since 2020. Last January i re-opened Electrum in that mobile , i found that i am not able to create a new seed (i have already three previous wallets). Anyone has an explanation?

I installed the mobile version of Electrum on my phone some time ago. I just checked the version and it is 4.1.5. Since version 2.0 is already out, it's safe to assume that Electrum doesn't get updated automatically. I don't remember whether or not there was an option to adjust update settings during the installation process. I don't have automatic updates turned on in Google Play Store because I handpick the apps that I want to update and when I want to do it. It might be different for people who have automatic updates on.  

The app i have installed is automatically updated and i can see changes since then. However, i can't find an explanation why the feature of creating a new seed doesn't work anymore. It's not a big issue though and i can use my old seed in another device with an updated version but i am looking for an explanation why/how this could happen.
Note that i am using a mobile version (Android) outdated and it could be different than the version designed for desktops. I can't tell that it's the same situation with IOS version as i made a long research to check if the issue is related to the mobile OP which is also outdated or it's a bug in the outdated wallet version.

It works, but you have to open one of your old wallets and enter your password first.
After opening your wallet, you can create a new one and generate a new seed by tapping on the three vertical dots -> wallets -> new.

In older versions it was possible to create a new wallet right after starting the app even if you have existing wallets. But this is no longer possible since version 4.1.0 due to the implementation of the Password unification feature.

I think it is not necessary, we don't need to enter a password. Just click create a new wallet below. After that, > create a wallet name > standard wallet > create a new seed.

They are talking about mobile Electrum which is the Android version.
Its GUI looks and works different than the desktop counterpart.

This is true for desktop versions but as nc50lc pointed out I was talking about the mobile version. As I said, the problem is caused by Password unification which for some reason was implemented on the mobile versions only.

* Password unification (Android only):...

In fact, this is not really a problem or a bug but this exactly how it's supposed to work (for safety reasons, you have to enter the password to confirm you know it first since it will be used to encrypt any new wallet you create).
