Hi Team,
We can check if we have Activex enabled for Internet explorer in javascript by creating object of Activex.

script type="text/javascript"

var activexObj = new ActiveXObject();

script

Throught that handler we can read the windows registry values

registryHandler.RegRead("HKEY_LOCAL_MACHINE\\Software\\Abc\\Version")

This is for Activex. But I want to read some more Keys from registry.

Key     Setting info                                                        Value
