On high security systems its a good idea to perform a secure delete of files or regularly write zeros to your free space to remove what remains of previously deleted files.
Secure Delete Windows
I came across this utility which seems to do the job perfectly. http://technet.microsoft.com/en-us/sysinternals/bb897443
Usage:
Securely erase a drives free space
sdelete -p 5 -z c:
This will write random strings to the free space on drive C: for 5 passes.
-p = Pass
-z = Zero free space
Securely delete a file or directory
sdelete -r c:\temp
This will securely delete c:\temp and all its sub-directories (1 pass)
