Saves a copy of specified subkeys, entries, and values of the registry in a specified file.
reg save <keyname> <filename> [/y]
| Parameter | Description |
|---|---|
<keyname> |
Specifies the full path of the subkey. To specify a remote computer, include the computer name (in the format \\<computername>\) as part of the keyname. Omitting \\<computername>\ causes the operation to default to the local computer. The keyname must include a valid root key. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. If a remote computer is specified, valid root keys are: HKLM and HKU. If the registry key name contains a space, enclose the key name in quotes. |
<filename> |
Specifies the name and path of the created file. If no path is specified, the current path is used. |
| /y | Overwrites an existing file with the name filename without prompting for confirmation. |
| /? | Displays help at the command prompt. |
