So you're lonely, it's late, and all you want is a companion.  So you dig out your old Michael Bolton CD, he always comforts you.  Today will be no exception.

You place the CD in to the CD-ROM, CD-WR, DVD-ROM, or DVD+-RW of your Windows XP or Vista computer, and wait for the magic to happen.  Waiting, waiting, wai...  WHAT THE £µ(|≤?!?!?!?!  WHY DO I HAVE NO MUSIC?

So you look in My Computer, or Computer in Vista, and there is no CD/DVD drive.  Why me?  Why now?

So now you check the Device Manager by going to Control Panels, then System, then Hardware and you see your optical drive has blasted little  yellow exclamation point next to it.  You double click it, and it says something like "Error Code 39" inside.  Or "Windows cannot load the device driver for theis hardware.  The driver may be corrupted or missing. (Code 39)"

Fret not, my friend, for the solution is near.

Hit Start, then Run, and type in regedit and press Enter.
Drill down by hitting the (+) plus signs next to:
+HKEY_LOCAL_MACHINE
+SYSTEM
+CurrentControlSet
+Control
+Class
+{4D36E965-E325-11CE-BFC1-08002BE10318}

If you see any of the following on the right side, right click and Delete them:
-UpperFilters
LowerFilters
UpperFilters.bak
LowerFilters.bak

Close the Registry Editor
Reboot your PC
Enjoy your Michael Bolton CD

De-Porning another PC.  Another one that should have been using something better than AVG.  Live and learh, eh?

Anyway, this one had a few issues that all came back to one, simple solution.  The issues I had were:

• Could not start the Event Log Service on Local Computer. Error 126: The specified module cannot be found
• And the Task Scheduler was similar: Error 1717: The interface is unknown

There are several other services and programs that this could effect.  A lot of things depend on the Event Log service to function correctly.  The fix is simple:

Grab a fresh copy of the event log dll, appropriately named eventlog.dll.  You can Google the file name or one is available here: http://www.driverskit.com/dll/eventlog.dll/769.html

The copy above is in a zipped folder.  Double click the zipped folder, then copy the eventlog.dll file.  Go to C:\Windows\System32 and paste it in there.

Now, to start the services hit the Start button, then run, and type in services.msc before hitting OK. Navigate to the the Event Log service, right click it, and hit Start.  Repeat with the Task Scheduler or any other failed services as needed.
