Question 83:IncorrectUsing the Windows OS, Joe transfers a file in his Documents folder to afolder that has been configured to give Ann full control of all files. Insteadof copying the files, Joe uses a move operation. Ann can read the file, butcan't save any changes to it.Which of the following is MOST likely the reason that Ann cannot updatethe file?Ann is not a member of theAdministrators group.Joe is not a member of theAdministrators group.The Modify and Write permissions forJoe were set to Deny on thedestination folder.The Modify and Write permissions forAnn were set to Deny when the filewas in Joe's Documents folder.Explanation

When a file is copied in Windows, it's given the permissions in thedestination folder, regardless of the original file permissions. When a file ismoved, Windows attempts to keep the same permissions that the file hadin the original folder. Most likely, the Modify and Write permissions forAnn were set to Deny when the file was in Joe's Documents folder.If Ann were a member of the Administrators group, most likely, she wouldhave been able to update the file. The file permissions are independent ofwhether or not Joe is a member of the Administrators group. If the Modifyand Write permissions for Joe on the destination folder were set to Deny,Joe would not have been able to transfer the file.References9.2.1 NTFS and Share Permissions9.2.2 NTFS and Share Permissions Facts9.2.3 Con±gure Basic Folder Sharing on Windows9.2.4 Con±gure Advanced Folder Sharing on Windows9.2.6 Con±gure NTFS Permissionsq_ntfs_modify_write_per_set_to_deny_pp7.question.fex

A large chunk of modern devices works on Windows operating system. Professionals know that all the necessary Windows settings are stored in the registry database. Multiple scenarios may arise the need to access the information and data or clean up junk files from the registry. Further, whenever any information is required, Windows only checks the same in the Windows registry.

Also, whether any reason or not, Windows users may need to check the registry periodically. Let us know all about the Windows registry in this section. We'll also go through the detailed steps to open the Windows registry editor and the detailed steps to use this registry. 

What Is Windows Registry

Different versions of the Windows operating system are available for the users. Starting with Windows 95, the Windows registry is in use. It is a hierarchical and centralized database for managing different application configuration settings, system resources, device drivers, user interfaces, security account services, etc. It can diagnose system errors and monitor system performance.

Windows registry has significantly reduced the need for several individual configuration files like .ini files and config.sys files, autoexec.bat files, etc. This registry mustn't be accessed or edited without knowing details about it. It is because it has all the essential configuration settings of the computer.

Users need "Regedit," which is the graphical tool to view, edit, or monitor the Windows operating system registry. It can make administrative-level or root-level changes to the system and the application's configuration settings connected to the registry. It is essential that only authorized users with permitted administrative access can use the "Regedit" tool. Let us go through the five main branches or hives of the Windows registry.

Five hives of Windows registry:

1. HKEY_CLASSES_ROOT: It keeps track of default file associations.
2. HKEY_CURRENT_USER: It has the username settings of Windows.
3. HKEY_LOCAL_MACHINE: Also called HKLM, it has security settings, software installation files, boot files, passwords, etc.
4. HKEY_USERS: It is used for logging multiple users into computers or servers.
5. HKEY_CURRENT_CONFIG: It performs real-time measurements of different hardware activities.
