The examples for the command "reg COPY /?"
The
`REG COPY` command in the Windows registry allows copying registry keys or parts of them. Here are some examples with technical explanations:
Example 1: Copying an Entire Key:
REG COPY "HKLM\Software\Source" "HKCU\Software\Destination" /s /f
-
`REG COPY`: The command to copy registry keys.
-
`"HKLM\Software\Source"`: The source key to be copied.
-
`"HKCU\Software\Destination"`: The target key where the source key is copied to.
-
`/s`: Copies the entire key tree (subkeys and values).
-
`/f`: Force execution without user confirmation.
Example 2: Copying a specific value:
REG COPY "HKLM\Software\Source" /v ValueName "HKCU\Software\Destination" /f
- This example only copies a specific value (
`/v ValueName`) from the source key.
Example 3: Copy with quotes in the path:
REG COPY "HKLM\Software\Source with spaces" "HKCU\Software\Destination" /s /f
- Here a source key is copied with spaces in the path. The quotation marks ensure that the path is interpreted correctly.
Example 4: Copying a subkey without values:
REG COPY "HKLM\Software\Source\Subkey" "HKCU\Software\Destination\Subkey" /s /e /f
-
`/e`: Copies the subkey without values. Only the structure of the key is copied, not the values ??within it.
Example 5: Overwriting without confirmation:
REG COPY "HKLM\Software\Source" "HKCU\Software\Destination" /s /f /y
-
`/y`: Overwrites existing targets without confirmation. Be careful when using this to force copy without confirmation.
Please note that changes to the registry can have irreversible effects. It is advisable to make previous backups and ensure that you understand the implications of the copy process. The
`/f` parameter is used to force execution without confirmation.
