Do you want to check it from web page? Or from program running locally on windows machine? – Ivan Nevostruev Jun 09 '16 at 22:55

@IvanNevostruev from web page By javascript. – BottledTurtles Jun 09 '16 at 23:03

2I don't think you can access any key in registry from web page javascript. Because it's security restriction. Registry can contain some sensitive information like login credentials. – Ivan Nevostruev Jun 09 '16 at 23:03

@IvanNevostruev i found somethings but all of them are written with ActiveXObject() which are not supported by Chrome... – BottledTurtles Jun 09 '16 at 23:05

Right. ActiveXObject is windows specific feature is only supported in Internet Explorer. Also it's not longer supported in latest Microsoft browser - Edge. Bottom line: it's possible in some old browsers, but will not be supported at all in future. – Ivan Nevostruev Jun 09 '16 at 23:10
