salt.modules.reg.import_file(source, use_32bit_registry=False)¶

Import registry settings from a Windows REG file by invoking REG.EXE.

New in version 2018.3.0.

Parameters:

• source (str) -- The full path of the REG file. This can be either a local file path or a URL type supported by salt (e.g. salt://salt_master_path)

Returns:

True if successful, otherwise an error is raised

Return type:

bool

Raises:

• use_32bit_registry (bool) -- Accesses the 32bit portion of the registry on 64bit installations. On 32bit machines this is ignored.

Returns:

A dictionary containing the passed settings as well as the value_data if successful. If unsuccessful, sets success to False.

bool: Returns False if the key is not found

If vname is not passed:

Return type:

dict

CLI Example:

The following will get the value of the version value name in the HKEY_LOCAL_MACHINE\\SOFTWARE\\Salt key

salt '*' reg.read_value HKEY_LOCAL_MACHINE 'SOFTWARE\Salt' 'version'

CLI Example:

The following will get the default value of the HKEY_LOCAL_MACHINE\\SOFTWARE\\Salt key

salt '*' reg.read_value HKEY_LOCAL_MACHINE 'SOFTWARE\Salt'

salt.modules.reg.set_value(hive, key, vname=None, vdata=None, vtype='REG_SZ', use_32bit_registry=False, volatile=False)¶

Sets a value in the registry. If vname is passed, it will be the value for that value name, otherwise it will be the default value for the specified key

Parameters:

• hive (str) --

  The name of the hive. Can be one of the following

  • HKEY_LOCAL_MACHINE or HKLM

  • HKEY_CURRENT_USER or HKCU

  • HKEY_USER or HKU

  • HKEY_CLASSES_ROOT or HKCR

  • HKEY_CURRENT_CONFIG or HKCC

• key (str) -- The key (looks like a path) to the value name.

• vname (str) -- The value name. These are the individual name/data pairs under the key. If not passed, the key (Default) value will be set.

• vdata (str, int, list, bytes) --

  The value you'd like to set. If a value name (vname) is passed, this will be the data for that value name. If not, this will be the (Default) value for the key.

  The type of data this parameter expects is determined by the value type specified in vtype. The correspondence is as follows:

  • REG_BINARY: Binary data (str in Py2, bytes in Py3)

  • REG_DWORD: int

  • REG_EXPAND_SZ: str

  • REG_MULTI_SZ: list of str

  • REG_QWORD: int

  • REG_SZ: str

  Note

  When setting REG_BINARY, string data will be converted to binary.

  Note

  The type for the (Default) value is always REG_SZ and cannot be changed.

  Note

  This parameter is optional. If vdata is not passed, the Key will be created with no associated item/value pairs.

• vtype (str) -- The value type. The possible values of the vtype parameter are indicated above in the description of the vdata parameter.

• use_32bit_registry (bool) -- Sets the 32bit portion of the registry on 64bit installations. On 32bit machines this is ignored.

• volatile (bool) -- When this parameter has a value of True, the registry key will be made volatile (i.e. it will not persist beyond a system reset or shutdown). This parameter only has an effect when a key is being created and at no other time.

Returns:

True if successful, otherwise False

Return type:

bool

CLI Example:

This will set the version value to 2015.5.2 in the SOFTWARESalt key in the HKEY_LOCAL_MACHINE hive

salt '*' reg.set_value HKEY_LOCAL_MACHINE 'SOFTWARE\Salt' 'version' '2015.5.2'

CLI Example:

This function is strict about the type of vdata. For instance this example will fail because vtype has a value of REG_SZ and vdata has a type of int (as opposed to str as expected).

salt '*' reg.set_value HKEY_LOCAL_MACHINE 'SOFTWARE\Salt' 'str_data' 1.2

CLI Example:

In this next example vdata is properly quoted and should succeed.

salt '*' reg.set_value HKEY_LOCAL_MACHINE 'SOFTWARE\Salt' 'str_data' vtype=REG_SZ vdata="'1.2'"

CLI Example:

This is an example of using vtype REG_BINARY.

salt '*' reg.set_value HKEY_LOCAL_MACHINE 'SOFTWARE\Salt' 'bin_data' vtype=REG_BINARY vdata='Salty Data'

CLI Example:

An example of using vtype REG_MULTI_SZ is as follows:

salt '*' reg.set_value HKEY_LOCAL_MACHINE 'SOFTWARE\Salt' 'list_data' vtype=REG_MULTI_SZ vdata='["Salt", "is", "great"]'

salt.modules.reg.value_exists(hive, key, vname, use_32bit_registry=False)¶

Check that the value/data pair is found in the registry.

New in version 3000.

Parameters:

• hive (str) -- The hive to connect to

• key (str) -- The key to check in

• vname (str) -- The name of the value/data pair you're checking

• use_32bit_registry (bool) -- Look in the 32bit portion of the registry

Returns:

True if exists, otherwise False

Return type:

bool

CLI Example:

salt '*' reg.value_exists HKLM SOFTWARE\Microsoft\Windows\CurrentVersion CommonFilesDir
