Although Cipher requires the path of a folder, it actually wipes all the
free space on the drive. This means that the commands cipher /w:c:\
Romulus and cipher /w:c:\Remus have exactly the same result.
Set up Cipher to wipe folders containing sensitive data at
regular intervals (or when Windows starts) to automatically
protect deleted data. See Chapter 9 for information on the
Scheduled Tasks feature and WSH scripts, both of which can
be used to automate Cipher.
Note that Cipher??™s /w option does not harm existing data, nor does it affect
any files currently stored in the Recycle Bin. It also works on unencrypted
folders and encrypted folders alike.
Control User Account Control
For years, Windows-based PCs have been under siege by viruses, spyware,
and adware, concepts introduced in Chapter 6. User Account Control, or
UAC, is Microsoft??™s response to this scourge in Windows Vista.

Users and
Security
It works like this: Windows Vista, like its predecessors, supports different
???levels??? of user accounts, some with administrator rights??”necessary to
install software and configure the system??”and others with lesser privileges.
But Vista doesn??™t give administrators carte blanche like Windows XP
and 2000. Instead, an administrator (you, for instance) operates in a morerestrictive
standard user account mode most of the time. Only when you
make a change that supposedly affects other users on your PC (whether
there are any or not), like installing a new hardware driver or changing Windows
Firewall settings, does Vista request your permission with the UAC
prompt like the one in Figure 8-12.
