Clear out junk and Optimize the W10-Image before installing afresh

[RealBlackStuff]

Can't say anything about this, other than it's probably a very good idea:
Optimize-Offline is a Windows Image (WIM/ESD) optimization module designed for Windows 10 versions 1803-to-1909 64-bit architectures.

Yes, perfect start to "Why my Windows 10 crashes?" It seems as all the stupid IT journalists have created the biggest fake news ever.

Sounds very much like a tool for only very experienced users right now.
First question I would ask is what does this do that ntLite doesn't do as well or at all? Haven't actually tried ntlite on Win10 yet but used it a lot for 7 (and nlite for XP previously).
