how do i delete upper and lower filters in the registry

[betts25]

1. I have an HPG60_441 Notebook, Operating System is Vista.  Every time iTunes updates their software, my CD drive ceases to work.  (TSST corp CDDVDW TS-L633M ATA device - "This device cannot start Code 10)  I believe I fixed it the last time by deleting the upper an lower filters in the registry, but I can't find the instructions I used to do so.  If I recall correctly, it was a very simple set of instructions and I didn't need to download anything.

I tried that option earlier this morning, but the "fix" couldn't read the cd drive either.

You asked if there was a guide on how to delete the upper and lower filters, which I provided in the link above under the Let Me Fix it Myself section.

Windows 7 or Windows Vista

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:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
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.
11. Exit Registry Editor.
12. Restart the computer.

Now go to the "More Information"section.

Windows XP

1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. In the navigation pane, locate and then click the following registry subkey:

4. In the right pane, click UpperFilters.

My apologies for neglecting to follow the link you left this morning.  I mistakenly thought it was a link to a "Fix It" tool I had tried earlier.  At any rate, your instructions were spot on and my cd drive is back up and running.  Thanks much.

You're very welcome.

I recommend you bookmark that link, because for whatever reason, Microsoft has removed it as an alternative to the automated fix-it page you get when you do a search.

I had to dig up one of my old posts to find it.

Glad the manual fix worked for you.
