Windows 10: Windows 10 Reset, does it really replace system files by new ones?

Im puzzled after Ive read this in Windows 10 Inside-Out:

Windows 10 reset accomplishes recovery operations by rebuilding the operating system to a clean state using existing system files.

Im puzzled at this by rebuilding the operating system to a clean state using existing system filesso it doesnt replace system files with new ones?

In fact, it goes on to say:
The reset option is a tremendous time-saver, but its not all-powerful. Your attempts to reset Windows can be thwarted by a handful of scenarios:
If operating system files have been heavily corrupted or infected by malware, the reset process will probably not work.
so system files arent really replaced by new ones (such as you do with a wipe and reinstall), how does a Windows Reset reinstall system files then? It fixes then somehow?

Does a Windows Refresh does the same in regards to system files?

Any clarification much welcome

:)

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
