Installed windows 7

Hey davidkrys,


Thanks for posting in Microsoft answers!


1.    Since when have you had this issue?

2.    Did you make any recent changes to your computer, after which the DVD Writer does not read and write?


This issue can be caused by incompatible CD/DVD-burning software or damaged registry information or the hardware is not compatible with Windows 7.


If you have installed any CD/DVD-burning software, please temporarily remove them.


Also, make a backup of the registry before proceeding with the below steps.


Refer the below link for details:


Backup the registry




Follow the below steps:


1. Click Start, and then click All Programs.


2. Click Accessories, and then click Run.


3. Type regedit, and then click OK.


If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.


4. In the navigation pane, locate and then click the following registry subkey:




5. In the right pane, click UpperFilters.


Note: You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 8.


6. On the Edit menu, click Delete.


7. When you are prompted to confirm the deletion, click Yes.


8. In the right pane, click LowerFilters.


Note: If you do not see the LowerFilters registry entry, unfortunately this content cannot help you any further. Go to the "Next Steps" section for information about how you can find more solutions or more help on the Microsoft Web site.


9. On the Edit menu, click Delete.


10. When you are prompted to confirm the deletion, click Yes.
