Windows users have profiles and permissions that restrict access to files and folders. File permissions are inherited from the parent folder.

File Permissions

Right-click a file or folder, then select Properties to view its permissions. Six permission types exist:

Use Properties → Advanced to change permissions.

Users without administrator privileges cannot access other directories in the Windows environment.

UAC

User Account Control (UAC) prevents unauthorized access without administrator permission and can be bypassed.
