On 25 Feb. a nice set of documents used by Microsoft in aiding the law enforcement authorities with forensics related to Windows Vista and Window 7 were leaked and first published on Public Intelligence.
They are a good read and explain a lot of what Microsoft does and does not do to keep your privacy in place and what kind of risks you are exposed when using these two operating systems and with a little background in security for your self you can start defending your privacy better.
The documents provide a great forensics insight and if you do care about your privacy then you should read them.
That there are 2 copies of notepad.exe in Windows? Yes that’s true! Check out Windows\ and Windows\System32 directories and you will see a copy of notepad.exe in each directory! \o/
Conclusion: Microsoft knew all the way that Notepad is the most valuable and appreciated default tool on Windows and put two copies of it in Windows just to make sure.
