A forensic analysis of the Tor Browser Bundle (version 2.3.25-6, 64-bit) on Windows 7 showed that the Windows Thumbnail Cache contains the Onion Logo icon.

Windows stores thumbnails of graphics files, and certain document and movie files, in Thumbnail Cache files. The following files contain the Onion Logo icon associated with the Tor Browser Bundle:

  • C:\Users\Runa\AppData\Local\Microsoft\Windows\Explorer\thumbcache_32.db
  • C:\Users\Runa\AppData\Local\Microsoft\Windows\Explorer\thumbcache_96.db
  • C:\Users\Runa\AppData\Local\Microsoft\Windows\Explorer\thumbcache_256.db

Other Thumbnail Cache files, such as thumbcache_1024.db, thumbcache_sr.db, thumbcache_idx.db, and IconCache.db, may also contain the Onion Logo icon.

An easy solution would be to drop the Onion Logo icon and have use a standard Windows icon instead.

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.
