Deletes a subkey or entries from the registry.

Syntax

reg delete <keyname> [{/v valuename | /ve | /va}] [/f]

Parameters

Parameter Description
<keyname1> Specifies the full path of the subkey or entry to be deleted. 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.
/v <valuename> Deletes a specific entry under the subkey. If no entry is specified, then all entries and subkeys under the subkey will be deleted.
/ve Specifies that only entries that have no value will be deleted.
/va Deletes all entries within the specified key. Subkey entries that reside within the specified key are not deleted.
