One of the first things I did after installing Windows 7, was to turn the UAC completely off to stop getting those annoying messages.
I have just read in this months PCPlus magazine that you should alter the default settings in UAC and slide the thing right to the top to give yourself more protection!
I'm not sure what's best now?
Have you turned yours off?
As I've mentioned in a previous thread, the first thing I do after installing Windows 7, is turn UAC up to it's maximum level so that it acts more like it did in Vista.
As it should be.
While I'd like to consider myself an advanced user (better than average maybe), I find that UAC on maximum settings is a useful tool that helps me to identify potential threats that may get past my firewall and antivirus.
Sure, when I install applications and/or drivers, it can be annoying, but what if I'm browsing the web, or use a CD/DVD/FlashDrive from someone else, and the UAC prompt pops up without warning, I'd know to cancel it and not allow access. I'm generally carefull about what I do on Prometheus, but knowing that Windows is helping does make the whole expierence a whole lot easier.
UAC is also great when you have kids at home that use your PC, or perhaps their own. Just setup a password-protected admin account for yourself, and let the kids use a seperate limited account without a password. If they try to install software, or attempt to do anything that could be potentially disastrous to the stability of the system (RegEdit, MSConfig, Drivers, etc...), then they cannot proceed without first entering a password, which only you should know.
When combined with the built-in parental control features, I no longer have any concerns about my niece using Prometheus when she visits, and I don't have to keep an eye on her.
UAC is not the evil big-brother that most make it out to be. It's already saved my neck (figuratively, of course) a few times in the past.
UAC on maximum setting is the only safe way to use it.
