How to delete cookies, cache and history in all major browsers

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.

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 :)

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.

Doesn't this delete bookmarks, too? I have a file called "bookmarks" in the directory that is deleted by the script.
