Vista - cd dvd rom issue after install

installed home premium yesterday. 32 bit.

the cd/dvd install took forever. when it finally finished i noticed that cd's/dvd's would not auto start. they seem not to want to open. found a possible solution below. the only problem is i don't have the upper and lower filters to delete in registry. help????

To resolve this problem, remove the affected filter drivers. To do this, follow these steps:

1. Click StartCollapse this imageExpand this image
   
   , type regedit in the Start Search box, and then click regedit in the Programs list.
   
   Collapse this imageExpand this image
   
   If you are prompted for an administrator password or confirmation, type your password, or click Continue.
2. Locate, and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
   Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
3. In the right pane, right-click UpperFilters, and then click Delete.
4. Click Yes to confirm the removal of the UpperFilters registry entry.
5. In the right pane, right-click LowerFilters, and then click Delete.
6. Click Yes to confirm the removal of the LowerFilters registry entry.
7. Exit Registry Editor, and then restart the computer.
