Windows Registry contains path to Tor Browser Bundle executable

A forensic analysis of the Tor Browser Bundle (version 2.3.25-6, 64-bit) on Windows 7 showed that the registry contains the path to the Tor Browser Bundle executable.

HKEY_CURRENT_USER, abbreviated HKCU, stores settings that are specific to the currently logged-in user. Each user's settings are stored in files called NTUSER.DAT and UsrClass.dat. The path to the Tor Browser Bundle executable is listed in the following two files:

  • C:\Users\runa\AppData\Local\Microsoft\Windows\UsrClass.dat
  • C:\Users\runa\AppData\Local\Microsoft\Windows\UsrClass.dat.LOG1

I did not find traces of the Tor Browser Bundle in any of the NTUSER.DAT files.

You'd never be able to remove OS "logging" under non-admin credentials. It is not a leak, but traces.

Please, don't invent new keywords out of the box and don't close tickets even if there is no obvious workaround or fix imaginable at the moment. Thanks.

Don't you see the difference between leaks and traces?
Disk Avoidance section in Design Guide describes what to be added to tbb-disk-leak. 5 invalidated tickets are about OS activity, not TBB. Are you going to fix Windows?
