Be aware that there are a lot of solutions, some paid (opportunistic), other free (maybe opportunistic and can hide amiss), but rare are those that are free and opensources...
I know that "classic shell" which has existed for years, free and opensource. His main interest is the "Start Menu" but other features are there that improve windows.
And if you feel like it, you can make a donation on their website Rather than pay for a missing feature of an expensive operating system already.
I invite you to discover the rest on their web pages
