You can't remove what isn't there.



That registry entry doesn't have an UpperFilters key as it is not of class DVD/CD-ROM Drives.



The value for the registry entry 4D36E965-E325-11CE-BFC1-08002BE10318 is GEARAspiWDM

How Do I Restore a Registry Backup if I Can’t Boot?




It really depends on the kind of failure that you’re experiencing.



I want to be clear about one thing when it comes to registry backups:
they are not a complete backup solution. Even if what’s preventing you
from booting is a registry issue, the only real, true backup solution
to the scenario that you described is a full image or machine backup.
A registry backup simply cannot save you from every possible failure
mode – even those that involve the registry itself.



How to restore your registry



I don’t know how your machine is failing to reboot – meaning I don’t
know exactly what symptoms you’re seeing – but see if you can boot
your machine in Safe Mode. During the early boot process, right after
the BIOS self test, press F8 to get the boot choice menu and select
the option to boot into Safe Mode.



Safe Mode can often sidestep some of the issues that prevent a full
boot from working and it’s perfect for restoring the registry. In
fact, that’s what most computer repair professional will choose when
doing a full registry restore.

I can't boot into Safe Mode.




For a full, catastrophic failure where the registry itself – or for
that matter just about anything – prevents you from rebooting into
Windows, a backup of the registry is simply not enough.



You may need a full system backup that you can then restore to get
your machine working once again.

You can't remove what isn't there.



That registry entry doesn't have an UpperFilters key as it is not of class DVD/CD-ROM Drives.



The value for the registry entry 4D36E965-E325-11CE-BFC1-08002BE10318 is GEARAspiWDM



See How to Delete the UpperFilters and LowerFilters Values for more information.





How Do I Restore a Registry Backup if I Can’t Boot?




It really depends on the kind of failure that you’re experiencing.



I want to be clear about one thing when it comes to registry backups:
they are not a complete backup solution. Even if what’s preventing you
from booting is a registry issue, the only real, true backup solution
to the scenario that you described is a full image or machine backup.
A registry backup simply cannot save you from every possible failure
mode – even those that involve the registry itself.



How to restore your registry



I don’t know how your machine is failing to reboot – meaning I don’t
know exactly what symptoms you’re seeing – but see if you can boot
your machine in Safe Mode. During the early boot process, right after
the BIOS self test, press F8 to get the boot choice menu and select
the option to boot into Safe Mode.



Safe Mode can often sidestep some of the issues that prevent a full
boot from working and it’s perfect for restoring the registry. In
fact, that’s what most computer repair professional will choose when
doing a full registry restore.

What if I can boot into Safe Mode?



If you can boot into Safe Mode, try the following:

I can't boot into Safe Mode.




For a full, catastrophic failure where the registry itself – or for
that matter just about anything – prevents you from rebooting into
Windows, a backup of the registry is simply not enough.



You may need a full system backup that you can then restore to get
your machine working once again.

I was able to start with Last Known Good Configuration. What do I do now?



You are good to go.




Last Known Good Configuration loads the drivers and registry data that worked the last time you successfully started and then shut down Windows 7.
