Windows 10: My storage space for apps and features is showing 145GB

So I'm trying to free up some storage and my apps and features are showing 145GB but when I go to sort them all in size the biggest one is only 1.79GB I know this isn't right because I have Steam and few games from there are 13GB but even then it wouldn't add up to 145GB because it only takes up 41.35806GB so wheres the 104GB hiding.

Apps & features disc space doesn't add up to storage use listed

Under "Settings," and "Storage," my OS_Install (C total size is 238 GB.

Under "This is how your storage is used and how you can free up space," it says...

Apps & features....98.8 GB

Yet even a cursory total of all programs listed (by size) under Apps & features reveals a total of about 1.5 GB.

And, a bunch of programs are listed at the bottom (including at least one that needs a lot of storage space) without *any* numbers.

Should I presume that the Settings -> Storage utility is incapable of listing ALL programs and all of the space they require?

Why the massive difference (98.8 GB vs 1.5 GB)?

 

Show storage space in This PC


I can't get This PC to show the storage space bars for my drives and I've done all that's been suggested in this thread.
Any ideas why I might not be able to make the storage space bars show?
