Comment (by tortestuser):

 According to [https://www.torproject.org/projects/torbrowser/design/
 Design Document of the TorBrowser.]
 "The browser MUST NOT write any information that is derived from or that
 reveals browsing activity to the disk, or store it in memory beyond the
 duration of one browsing session, unless the user has explicitly opted to
 store their browsing history information to disk."

 I can confirm this bug is in windows 7 64bit by following steps 1-4, and
 it has a related solution.  Ensure the enviroment has the TEMP/TMP
 enviromental variable are set properly for each os to point to a relative
 directory, and failing that, do not use api calls that create temp files.
 For my computer TEMP=C:\Users\tortestuser\AppData\Local\Temp according to
 Process Hacker, and that is where the files are created.

 I have attached a picture with visual proof of the problem.
