As I've quoted in the procedure of using cleanwipe,

Running CleanWipe
=================

To run CleanWipe on 32-bit operating systems:
---------------------------------------------
1. Copy the CleanWipe folder to the target computer.

2. Open the CleanWipe folder and double-click the CleanWipe.exe file.

3. When you are prompted, browse to a location where you want the files to be copied and then click Start to extract the files. 

If you click Start without selecting a location, the files are extracted to the Windows\Temp folder.

4. When you are asked if you want to run CleanWipe now, click Yes to run CleanWipe immediately; click no to run CleanWipe later.

5. As you run CleanWipe, you are prompted several times. It is recommended that you click Yes in response to all prompts.  

If you choose to run CleanWipe later, browse to the CleanWipe\app folder and double-click the RunCleanWipe.bat batch file. Remember to click Yes in response to all prompts.

The procedure quite good but based on my experience, if you select Yes in response to all prompts, you will encounter problem related to network driver. Meaning, your driver for LAN will also removed. To avoid that, during process,  you must select "No" in Uninstall Drivers windows.
