The UAC appears to give me grief constantly, it seems like every error I get with installing software stems from permissions issue.

So I went to turn off the UAC today on a server just to confirm if it made a difference.
To turn it off:

• go to Administrative Tools -> System Configuration -> Tools tab
• scroll down to Disable UAC and click to select
• then click Launch and note that it will require a reboot of the server

Apparently it does not turn it off fully, as I still needed to use Run as Administrator despite my logged in account being specifically added to the local computer administrators. Seems odd and it did not fix the specific error I was looking at, so I turned it back on.
