Anyone know of a good free music score-writing program for PC (not Android or Apple)?

I'm looking for some free/open source music score-writing software. What I'm assuming must already exist is an interface where you start off by entering in the key of the score you are writing, then the time signature of it, then you specify whether you need both treble clef lines and the base clef lines, then the software spits out a starting template for you; which you can just keep adding as many bars to as you want. Then you proceed to insert whatever notes and rests into the score you want at your leisure, from a 'bank' of different note symbols (quaver, crotchet, minim, etc.) and rest symbols that appear down the left side of the screen in a vertical line/group (like in PhotoShop).

Ideally it would be good to be able to also insert symbols for 'accidentals', ties (that is a bit of a big ask I guess), staccato notes, etc., but that's not essential (I could always 'chuck those things in later' with PhotoShop; or with a pencil on a printout). Similarly, it would be good if the software enabled the insertion of all the symbols for loundness (pp, p mf, f, ff, etc.), and all the lovely Italian words for different 'moods'/speeds etc.; but again, that's not essential. What I really want is software that I can use to generate digital versions of scores I want to write that include at least the key, time signature, and notes.

I guess the 'hard core' composers out there will be wondering why I don't just buy a few blank manuscript exercise books, and 'go from there' with a pencil. The reason is that I'm sick of all the erasing that this approach entails, whenever you decide to change a score. It would be great if the whole score generation process was digitised; like constructing an MS Word document or something.

If anyone knows of such software, please comment below.

Thank you.
