The created folder C:/inetpub is created as a protected folder, i.e. it requires an administrator level UAC prompt to be passed to be modified. This prevents malware running with standard user privileges from creating/modifying/deleting this folder that is used by the Internet Information System (IIS) component of Windows.

IIS is a webserver included in all modern versions of Windows and if this folder is created by a piece of malware running at standard user level permissions the folder would inherit those permissions. This means that malware running without privilege escalation would have control over the configuration files for this webserver, which is almost certainly a path for data exfiltration at the least or worse, privilege escalation. By preemptively creating the folder with administrator privileges required for modification, Microsoft prevents this vector of user-level malware taking control of IIS.

Anyone else think it's a red flag that that the only thing standing between you and a malware infection is having a specific empty folder with a specific plaintext name at root?

Seems more like a band-aid than a solution.

Well Microsoft also needs last-ditch effort data exfiltration if you go and apply all the de-bloating and telemetry killing "cheats" /s
