Reg command using the detailed batch operation registry required _dos/bat

Edit the registry directly only if you have no choice. Registry Editor ignores standard security measures so that these settings degrade performance, damage the system, and even require users to reinstall Windows. You can change most registry settings by using Program security in Control Panel or Microsoft Management Console (MMC). If you must edit the registry directly, back it up first. Edit the registry of the local or remote computer directly using Reg. These changes may cause the computer to not operate and require the operating system to be reinstalled. So do not edit the registry directly, but make the registry change as much as possible by using Control Panel or Microsoft Management Console (MMC). Some operations can view or configure registry keys for local or remote computers, while others only allow you to configure registry settings for the local computer. Also, remote access to the registry may limit the parameters used for an operation. Check the syntax of each operation to verify that the operation is available to the remote computer, and to verify the parameters that can be used in that case.

　 The reg command is provided by Windows XP to add, change, and display registry subkey information and values in registry keys.

1,reg Add new subkeys or items to the registry
Syntax: REG ADD KeyName [/V entryname|/ve] [/t DataType] [/s separator] [/d] [/f]
Parameters
KeyName
Specifies the full path of the subkey. For a remote computer, include the computer name in front of the subkey path in \\ComputerName\PathToSubkey. Ignoring computername causes the default to operate on the local computer. Start the path with the appropriate subdirectory tree. Valid subdirectory trees are HKLM, HKCU, HKCR, HKU, and HKCC. There are only HKLM and HKU on the remote machine.
Value Description
Hkcr:hkey_classes_root
Hkcu:hkey_current_user
Hklm:hkey_local_machine
Hku:hkey_users
Hkcc:hkey_current_config

/V EntryName
Specifies the name of the item to add to the specified subkey.
/ve
Specifies that the entries added to the registry are null values.

Reg_dword
REG_Binary
Reg_dword_little_endian
Reg_link
Reg_full_resource_descriptor
Reg_expand_sz
