I have a CZ-17 laptop (from iBuyPower, subbrand of MSI I hear) running Windows 7 64x SP1.
The keyboard and touchpad both stopped working after I cleaned my registry with CCleaner and defragmented the OS partition of the HDD with Defraggler. (The defragmentation process has not been interrupted.)
The ELanTech Touchpad
The touchpad icons have not been loading in the task bar tray at startup. Neither could I manually start the applications associated with the touchpad from my Program Files on Drive C. 
Here is what I have tried without results:
1. Switch on the touchpad with the designated laptop function key combination (Fn + F3)
2. Restore the system to an earlier point.
3. Uninstall the device from device manager, restart and let Win7 install the right drivers and what not.
4. Install various drivers, including manufacturer recommended.
As of now the touchpad is hidden in the device manager and is marked with an exclamation sign. Under properties I see : This device is not present, is not working properly, or does not have all its drivers installed. (Code 24). 
I am using a USB mouse as I write this.
The Laptop Keyboard:
The keyboard stopped working at the same time as the touchpad (after registry cleaning and defragmentation).
Most of the time I was able to use a USB Keyboard to be able to try to fix the problem. A few times, however even the USB keyboard would not work. I noticed that when I uninstalled the ElanTech Drivers for my touchpad I saw the yellow sign with an exclamation mark for keyboards in the device manager. Under properties I could see the error: Code 19: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged.
I have read that some recommend manipulations with the registry. I tried to remove the Upper Filters for both the mouse and keyboard (I had no idea what I was doing...) and my usb devices also stopped working. I was able to reboot to the last good version and reclaim some degree of control over my machine. 
Noteworthy: The laptop keyboard works fine in BIOS.
I have spent quite some time researching this but none of the things I came across helped me fix the described issues... Yet (:

Did you happen to back up the registry files that were "cleaned" with CCleaner? It will do so by default.

Sounds to me as if your OS has been optimized FUBAR style.

Perhaps a repair install or running sfc /scannow from DOS will help...?
