Yesterday, I configured a skin that is requires PHP versions 7.4.3 and up. My current PHP version is 7.3.33; the problem is that I don't know how to update to the latest version of PHP.
Can anyone explain this?

Depends on your operating system/linux distro (please say which one). If its a shared host you might not even be allowed to.
I am using Windows 10.
Is your webserver windows 10? (As opposed to just the computer you are using) - is that what the Special:Version page of your wiki says?
Windows 10 doesn't come with php by default, so upgrading would be the same as however you installed (of which there are multiple possibilities, so it depends which one you used)
