Reading and writing values in the registry is the same regardless of the format. In the case of REG_BINARY the returned object is of type byte[]. The following code would convert that to a string. You would reverse the process to write it back. RegistryKey regKey3 = Registry.CurrentUser; RegistryKey regSub3 = regKey3.OpenSubKey("Software or whatever"); byte[] ans = (byte[])regSub3.GetValue("Value I need"); string sString = System.Text.Encoding.ASCII.GetString(ans); string [] sArray = sString.Split('\0'); sString = ""; foreach (string s in sArray) { sString += s; } Now sString should have your string from the reg_binary ready for processing. If you have knowledge, let others light their candles at it. Margaret Fuller (1810 - 1850) [My Articles]  [My Website]
