Alternatively run REGEDIT MYKEY.REG from the command line.

How to delete keys and values from the registry:

Create a reg file like this, notice the hyphen inside the first bracket

[-HKEY_CURRENT_USER\SomeKey] When double clicking this .reg file the key "SomeKey" will be deleted along with all string, binary or Dword values in that key.
