You cannot do this for Windows as a whole (and even if you did, users
could just use a Print-Screen instead, to pass on restricted data). But
you can do it for specific applications: the key technology is Windows
Rights Management Services ("RMS"). See
http://www.microsoft.com/windowsserver2003/technologies/rightsmgmt/default.mspx
If you have an application which can take part in an RMS infrastructure,
then you can indeed configure policies to selectively permit or prevent
cut-n-paste, etc, to specific users and groups; or disallow cut-n-paste
altogether, in that application.
Microsoft Office is the most common app which can plug into RMS. Once it
is all set up, it is extremely effective ... you really want to
cut-n-paste confidential info from that juicy email or Word document; but
dammit, you just can't! You also cannot forward protected emails, etc.
There is a public SDK, so anyone can write an application which subscribes
to RMS and restrict access to the app's data. However if you have a legacy
application (ie, an already-existing application) which you cannot
re-engineer, then I think you are kind of stuck. You may need to approach
the security question from a non-computer perspective, such as HR
policies, etc.
You might also take a look at Software Restriction Policies ("SRP"), a
similar security feature in Windows. SRP won't stop users from cutting and
pasting, as such; but it does let you create a very controlled
environment. You can stop users from doing many things you don't want them
to. See:
