I thought I would outline a problem I had today with the solution that worked for me:
Error: “This file does not have a program associated with for performing this action. Create an association in the Set Associations control panel.”
The occurred after some Windows Updates, and occurs when I insert a DVD into my drive, I open “My Computer” and double-click the CD/DVD drive.
Here’s what fixed it for me:
Backup the registry before proceeding:
1. Start -> Run -> “regedit.exe”
2. At the very top of all folders, right-click “Computer” and choose “Export.”
3. Save the file on your desktop.
Modify the registry:
1. Navigate to: HKEY_CLASSES_ROOT\DVD\shell\play\command
2. Open the (default) key.
3. Is it blank? Mine was. I want my DVDs to open with Windows Media Player, so I added this:
C:\Program Files (x86)\Windows Media Player\wmplayer.exe /prefetch:4 /device:DVD “%L”
