First, I'd like to apologize for the selection of the forum. I couldn't find any more fitting forum for this. I have been running as admin and moved to using protected admin with Windows Vista. Continued the same behaviour with Windows 7. But now I'm building a new computer and after reading good things about LUA + SRP combination which many people here seem to use, I have thought that maybe it is time to start using Standard User for day-to-day tasks. My questions are: Will I be able to install new software or even drivers with Standard User, if I give the Admin account credentials? Is there any difference on this matter as opposed to the Protected Admin? If I'm able to do it, will it install the software for my Standard User or my Admin account? I mean that sometimes installers ask that who you want to install the software for, yourself or all users on this computer, so I'd like to know that if I choose "yourself", does it mean the Standard Account which I'm using or the Admin which's credentials I gave for the installation?
