Defraggler
Defraggler is a defragmentation utility from Piriform (the authors of CCleaner and Recuva).
Defraggler is available from https://www.piriform.com/defraggler
The standard installer (as of version 21) includes a bundled offer to install Google Chrome. To prevent this installation of Google Chrome when doing a silent install of Defraggler requires adding registry keys.
Registry files
Create two files 32-disallow-chrome.reg and 64-disallow-chrome.reg in the same folder with the defraggler install

Alternative use of Portable Build
It usually takes Piriform a week or two to put the slim installer on their website for download. If you don't want to wait you can download the portable version and copy the files directly into Program Files to upgrade Defraggler.
You can download the portable version here: http://www.piriform.com/defraggler/builds. Extract the Zip archive and use this package to copy the portable files to your system. This does not create any shortcuts, but leaves the link to the uninst.exe to remove previous 'slim' or 'regular' installs.
