Add keys and values to the registry:
Create a text file like this:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\SomeKey]
"SomeStringValue"="Hello"
Note the registry file should contain a blank line at the bottom of the file.
When double clicking this .reg file the key and value will be added. Alternatively run REGEDIT
MYKEY.REG from the command line.
Delete keys and values from the registry:
Create a reg file like this, notice the hyphen inside the first bracket
Windows Registry Editor Version 5.00
[-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.
If you want to just delete values, leaving the key in place, set the value you want to delete = to a
hyphen
e.g.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\SomeKey]
"SomeStringValue"=-
Again double clicking this .reg file will
delete the values specified, or you can use
REGEDIT /s
MyDeleteScript.REG

Windiff
is your friend, this simple GUI utility from the
resource kit
will list all the differences.
Add Comments
Within a registry file, comments can be preceded by "; "
e.g.
;
; Turn
the NUMLOCK on at login
;
[HKEY_CURRENT_USER\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"
Batch files will ignore any semicolons before a command, so this can be used to create a
self-
contained registry script
.
Under Windows NT 4 all registry scripts start with:
REGEDIT4
(This version string will also work
in XP and later versions of Windows.)
