I've seen the list of values floating around the internet for ClearMyTracksByProcess

Delete Temporary Internet Files:
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8

Delete Cookies:
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2

Delete History:
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 1

Delete Form Data:
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 16

Delete Passwords:
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 32

Delete All:
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 255

Delete All + files and settings stored by Add-ons:
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 4351

But it's not a complete list of all the options, and I can't seem to find a complete list (whether there isn't one published, or this one has been republished too many times and is hogging all the search results, I'm not sure).

What I'm looking to do is delete Cookies + Temp + Add-ons, but preserve History, Form data, and Passwords. Has anybody found a complete list of all the available options? Or just the option for Add-ons so I can do the math myself? (e.g. Add-ons value + 8 + 2 = the answer I'm looking for)

Thanks for looking at my question!

Its much easier to use CCLEANER, to remove Temporary files, history, cookies, super cookies, Autocomplete form history, index.dat files.

Here you can select What you want to delete? and What to Retain?.

For example:
You can delete cookies while preserving History and Password.
