I don’t think I’ve used any cleaner product since the Windows XP days. I don’t view it as necessary anymore.
One of the other programs to see file size on disk recommended on this thread should be enough.
I would highly recommend O&O ShutUp10++ to reduce built in spying in Windows. It’s good at explaining what each option you’re doing is. The only thing I would caution on is changing the Edge browser policies with O&O. That will lock it down into enterprise mode and you won’t be able to change certain settings through the UI anymore.
