Why are the good old security advices gone


What happend to basic security advices. You nearly don't hear about them anymore.
Im talking about Limited User Account (LUA) and Software Restriction Policy
Today its all about IE features + big security suites, comodo firewall and
fancy removal tools.
With LUA and SRP all your family desktop/laptops, will newer get infected.
Why has Microsoft and most of the Security MVP's given up on these security
They are not even listed here:

Please also remember that UAC in Vista was not ment to be a security
boundary, from what I have read.
Any comments?.
