I ran into a little problem on a client’s computer recently and I thought I’d share the accumulated research I had done to fix it. I won’t go into details, so this post if probably just for you nerds out there, but I hope it helps someone!
This is the complete list of potential fixes that I found for a Windows XP based computer that refuses to autoplay any CDs or DVDs. You won’t need to run ALL of these, nor can I guarantee these items won’t break something, ESPECIALLY if done improperly! Note that some registry keys listed are specific to Windows XP.
- Run the Microsoft Autoplay Repair Wizard, if it doesn’t find and fix problems then it does a debug mode! You may need to run this more than once as well.
- Set the following: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
\CDRom\Autorun = 1 (may also be in CURRENT_USER keys) - Set the following: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer\NoDriveTypeAutoRun = 91 (hex) - Set the following: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
\policies\Explorer\NoDriveTypeAutoRun = 91 (hex) - Search the registry for all NoDriveTypeAutorun values and NoDriveAutoRun values and delete them
- CDRAutoRun = 1 (or delete it)
- Set the following: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\allocatecdroms = 0 (also current_user?)
- Set the following: HKLM\SYSTEM\CurrentControlSet\Services\Cdrom\Autorun = 1
- Delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
\IniFileMapping\Autorun.inf - Search the registry for all “HonorAutorunSetting” and delete them
- Set the following: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer\”NoSaveSettings”=dword:00000000 - Check for CD restrictions in Group Policy Editor: Computer Configuration > Administrative Templates > System
- Uninstall RealPlayer
- Use TweakUI 2.10 to reset Autoplay settings
- Use msconfig
- Search www.adaptec.com for aspichk
- Run Doug Knox’s XP_CD-DVD-Fix.exe
Good luck and let me know if this helped you!
