On which objects, except folders and files, can I put permissions in Windows?

The answer can be found in the description of the SetSecurityInfo function. Specifically, it is:

• SE_FILE_OBJECT - file or folder

• SE_SERVICE - Windows service

• SE_PRINTER - printer,

• SE_REGISTRY_KEY and SE_REGISTRY_WOW64_32KEY - registry key,

• SE_LMSHARE - network share (I do not know how in Russian - a network resource?),

• SE_KERNEL_OBJECT - a kernel object, that is, an event, a mutex, a process, a socket, a timer, and so on, many of them,

• SE_WINDOW_OBJECT - desktop,

• SE_DS_OBJECT and SE_DS_OBJECT_ALL - directory service object in X.500 format

• SE_PROVIDER_DEFINED_OBJECT is probably an object defined by some driver,

• SE_WMIGUID_OBJECT - WMI object.
