But recently small compiled received some users report, that is the computer upgrade to the Win7 flagship version, incredibly can not start DVD drive, this is what?

1. First, we press Win+r's shortcut key to start the computer's running window, then enter the regedit command in the window and click Enter, so that the computer's Registry Editor window can be opened.
