I was so happy when I thought I finally had it licked. Back in February, I did something I almost never do; ran the registry cleaner in CCleaner. After that, my explorer.exe crashes disappeared, forever, I hoped. Oh well.

It used to crash several times a day and either restart itself or prompt me to do it. It occurred more frequently when the DVD drive was in use, but could do it any time, whether I was using explorer or not. I read somewhere that someone had fixed his by cleaning the registry with CCleaner. Out of ideas, I gave it a try, and voila... all better. Until I plugged in a DVD today. I have probably used the drive 10 times since the crashes disappeared.

I haven't seen much in forums about it lately, but I wonder if everyone that had the problem figured out what (many things, I believe) was causing it, or if they just gave up. Either way, I figured I would post the event viewer log and ask if there any new revelations about the problem.
This is Windows 7 Home Premium 32 bit.

They all say the same thing.
Thanks for any thoughts on the matter,

Did you try making a backup and restoring the backup of the CCleaner Registry cleaner?

That would assist you now.

Otherwise see if you can revert the pc to a earlier stage before CCleaner.

nNot sure if im seeing all this message properly though .

Otherwise i cant see a EASIER fix.

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:

• Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.

• Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.

• Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.

• Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.

• The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

It seems related to having a DVD in the drive, but that might not be the direct cause...it could just be a symptom of some other underlying issue.

How about posting some full system specs?

Try running a sfc.
