About this tag
System folder protection in Windows refers to the operating system's mechanisms for safeguarding critical directories from accidental modification or deletion. A recent example involves the April 2025 Windows cumulative update (KB5055523 for Windows 11, KB5055518 for Windows 10) creating an empty 'inetpub' folder on the C: drive, even on systems without IIS enabled.
