Registry Routines
The
Shell
object provides Windows Registry
access through the
RegRead
, RegWrite
, and
RegDelete
methods.
When accessing a Registry key, you must specify the path. The path is built from the Registry hive name (the name of one of the major Registry branches described in Chapter 8), followed by the path to the key separated by backslash characters. Table 9-8 lists the hive names.

.
One way to easily get the path for registry values is to use the RegEdit application to search for Registry information and copy the key path to the clipboard using Edit → Copy Key Name. The Registry routines do not provide the ability to list any values under a particular key, so you need to know the path to any Registry values you wish to reference.
RegRead
RegRead
reads the registry value from the
specified Registry path:
strVal
= objShell.RegRead(strKeyPath
)
strKeyPath
is a path to the Registry value you
wish to read.
Set objShell = CreateObject("Wscript.Shell") Wscript.Echo "Your Windows Version Number is " _ & objshell.RegRead _ ( "HKLM\Software\Microsoft\Windows\CurrentVersion\VersionNumber")
RegWrite
RegWrite
writes a value to a specified key value or creates a new key: ...
