I read here about WinWSD, but there was no download link in that article. :(
Hello, if the link in the article is not available, you could try downloading it from CNet:
I think you are referring to this article: Download Entire Websites To Read Offline With WinWSD
The link to WinWSD is in the second paragraph of the article.
Unfortunately, it seems that the site is no longer available.
Similar apps are suggested in the third paragraph of the same article: Scrapbook and HTTrack. Maybe you can receive more suggestions here.
