With WSH you can manage the system registry. The following scripts demonstrate some of these capabilities.
// JScript.
Sh = new ActiveXObject("WScript.Shell");
key = "HKEY_CURRENT_USER\\"
Sh.RegWrite( key + "WSHTest\\", "testkeydefault");
Sh.RegWrite( key + "WSHTest\\string1", "testkeystring1");
Sh.RegWrite( key + "WSHTest\\string2", "testkeystring2", "REG_SZ");
Sh.RegWrite( key + "WSHTest\\string3", "testkeystring3", "REG_EXPAND_SZ");
Sh.RegWrite( key + "WSHTest\\int", 123, "REG_DWORD");
WScript.Echo( Sh.RegRead(key + "WSHTest\\"));
WScript.Echo ( Sh.RegRead(key + "WSHTest\\string1"));
WScript.Echo ( Sh.RegRead(key + "WSHTest\\string2"));
WScript.Echo ( Sh.RegRead(key + "WSHTest\\string3"));
WScript.Echo ( Sh.RegRead(key + "WSHTest\\int"));
Sh.RegDelete(key + "WSHTest\\");
' VBScript.
Set Sh = CreateObject("WScript.Shell")
key = "HKEY_CURRENT_USER\"
Sh.RegWrite key & "WSHTest\", "testkeydefault"
Sh.RegWrite key & "WSHTest\string1", "testkeystring1"
Sh.RegWrite key & "WSHTest\string2", "testkeystring2", "REG_SZ"
Sh.RegWrite key & "WSHTest\string3", "testkeystring3", "REG_EXPAND_SZ"
Sh.RegWrite key & "WSHTest\int", 123, "REG_DWORD"
WScript.Echo Sh.RegRead(key & "WSHTest\")
WScript.Echo Sh.RegRead(key & "WSHTest\string1")
WScript.Echo Sh.RegRead(key & "WSHTest\string2")
WScript.Echo Sh.RegRead(key & "WSHTest\string3")
WScript.Echo Sh.RegRead(key & "WSHTest\int")
Sh.RegDelete key & "WSHTest\"
