debloated ISO > original ISO installation and debloated > original
that's why an LTSB version (debloated by MS themselves) is so much faster than Win10 Pro
unfortunately, debloating iso ourselves is not very easy and can take many experiments and trials with bugs and missing features to find an optimal iso
using a downloaded lite version may not suit our needs or has a privacy issue. Example, I find Ghost Spectre windows 10 is the best in both speed and stability but he removed Windows Smartscreen

Somehow, I managed to get it back but I don't remember how
sfc, dism or windows updates may potentially break the purpose of bloating iso
