I can’t upload files using Git bash on windows 8

When i try to upload files using gitbash it says ".NET framework v4.7.2 is needed" but unfortunately its not supported on windows 8 and I cant upgrade to windows 10 for now so can someone suggest another way of doing so because I’ve heard drag n dropping files directly to github is not a good way to do so. (I have many files to upload)
