I know gpedit.msc, lets try this one install IDM (internet download manager) Note : After download. It will ask to install in c: drive don't install, just install in other drives like "D:Internet download manager", it will work, and my company senior programmer also do same thing, but i will do this trick, this works, for me smoothly.....or use youtube downloader portable "No need to install", just works, peeeerfectly....
