This also doesn't get rid of Flash Cookies / LSO's. The wiping of LSO's badly needs to be part of standard browser functionality. When I click "Clear All History & Cookies" it should actually clear ALL history and cookies... not all local cookies while leaving all the flash stuff tracking me.
Oh snap, I totally forgot about these. Writing a script to clear those and updating the blog post. Thanks!
Agreed. Better Privacy for Firefox is pretty good for this but I would like to see secure deletion of user data for plugins be a core part of the browser and not an extension. They added stupid "personas" before deleting secure history deletion :(
Good post but two things I would change.
Firstly I would use sdelete from Microsoft (formally Winternals). It is a free command line secure delete utility. Just replace
del /q /s /f in the Firefox example with sdelete -p 2 -s and it will securly delete the files with 2 passes (although 1 should be fine for everyone to be honest).
Secondly there is no need to compile the OPs regdelete app as you can use the built in reg.exe to do this
Just do
reg delete "HKCU\Software\Microsoft\Internet Explorer\TypedURLs" /f
And the same job is done :)

I couldn't get that reg working for some reason. But awesome tip on sdelete!
Depending on how thorough you want to be, don't forget evercookies

I feel like it's important to note that this is actually obliterating the entire user profile. Bookmarks, saved passwords, and extensions included. Unless I'm mistaken, which is certainly possible.
Also, for Windows, CCleaner.
