Re: [WIN8] Windows 8 / CD-DVD driver issue

Also, can you check the following registry key?:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

At that registry key, in the right window, is there, under "Name", either an UpperFilters or LowerFilters value?

If so, for each of the UpperFilters and/or LowerFilters value, what is listed under "Data"?

LowerFilters = PxHlpa64
UpperFilters = GEARAspiWDM

One or both of those entries may be invalid.

Can you check the C:\Windows\System32\drivers folder and see if either PxHlpa64.sys or GEARAspiWDM.sys exist in that folder.

If either or both are missing from the C:\Windows\System32\drivers folder remove the corresponding registry entry.

If PxHlpa64.sys is missing then double-click LowerFilters and remove PxHlpa64 > OK

If GEARAspiWDM.sys is missing then double-click UpperFilters and remove GEARAspiWDM > OK

Create a system restore point beforehand and restart the computer afterward.
