Wow mitch, thanks for all the great info!
Sorry I've been a bit scarce, since my last reply in this thread.
Like ripley, I'm so grateful for the help and support of the more savvy and experienced members (geek or not!); I really
treasure every comment I read from such professionals. And I also must admit to wanting a list of rules (simple or not), although I can't really say it comes from laziness, for me. However, this does shed some light on something that's been both confusing and frustrating for me, regarding the internet and tech support in general.
I don't know, maybe I'm just "old school", as they say

I've only had a pc and internet access for a few years, but I've been aware of, and understood the general idea of computers and the internet since college (in the late '70's).

Yeah, or maybe "old flower child"

would be apropos

LOL! Because
my understanding of the original concept of the internet (or www?), as a medium, or tool, for facilitating the uninhibited free-flowing exchange of information, is very much like the idealism that I associate with the 60's generation....or maybe the concept of 'community', at its most basic, ie -- give whatever you can, take whatever you need, everything will balance out in the end. (I realize that many folks consider this to be a naive perspective....so call me naive

, and read on

)
So when I first came to the internet, I expected an abundance of websites and forums whose goals are to help people. And not just offering computer classes and technical support, but educational content for everything imaginable. I expected people to be offering these things out of the goodness of their hearts, simply because they want to help others, and asking nothing in return! Once I managed to learn how to work my computer, and I got to the internet, I was
shocked and dismayed at the blatant commercialism! Instead of teaching everything imaginable, people are using the internet to
sell everything imaginable! (as I said...call me naive

....)
However, despite all the commercial pollution, up until the last few months, I still believed this free educational content must exist, and that I have just not found it, or learned enough to find it yet. But I was becoming increasingly frustrated at the apparent lack of content and support for beginners. I definitely find plenty of educational info available (witness LzD)...just precious little designed to assist rank beginners. But given my belief that such content and support are inherent aspects of the internet, my frustration has lately been changing to anger....until now.
I don't think I can really verbalize entirely how this belief began to change for me. Part of it is the realization that I'm no longer a mere novice, but perhaps have reached the level of an intermediate- or advanced-beginner...all on my own, without yet having found the educational material which I thought was part and parcel of the internet. And mitch's and ripley's comments in this thread have really gelled this new concept for me -- it's not
just this limited user account for enhanced security, for which there is "no list of easy rules" or instructions. Indeed, I'm beginning to think it's more the exception than the rule, that any given computer issue will have clear-cut rules.
So, talk about long-winded! Anyway, it's just...when you hear things like "it's all ones and zeros", and you begin to understand the concept of "digital"...well, maybe not "you", but
I think, everything about computers must be very structured, regimented, and ultimately, clear and understandable...ie - rules and list for everything imaginable. But mitch's and ripley's comments in this thread have really reinforced for me the notion that information, educational content and/or tech support are not necessarily available for every issue that one might encounter, in teaching oneself computer literacy/proficiency.
And why am I posting this discourse? Partly to explain myself. Not so much an apology, for everyone has their own learning curve

But just to shed some light on my original motivation here at LzD. This new understanding of the nature of computers and internet, will undoubtedly affect my use of all support forums -- hopefully resulting in more thoughtful requests for help...more patience with complex, yet helpful, replies...to name a couple of potential adjustments. And partly in case there may be other members who might benefit from reading/hearing my thoughts, perceptions, and experience.
And finally getting back to the topic of this thread:
"using different users can be a "black art""
I hope by this, mitch, you mean that not many people actually use the limited user account as a security measure, or that it's not widely understood as such...as opposed to there being something dark and unnatural about it?
Oh, Windows Explorer, yes I know what that is. I just have never heard it called an "expanded windows folder". I normally make fairly heavy use of it, and not sure it will help me understand, since I may have moved a program to another folder, besides where it was installed. ...or am I still missing your point? In my C drive, I have Owner (the admin), Brynn (the new limited user), and All Users. But all the security programs are in All Users. Is that what you would expect?
Well, the bottom line, I
do understand, is that I have to dig into each program's documentation, to find out how it treats the limited user accounts -- not just in regard to what it scans, or from where; but also in regard to dl-ing and installing. And I do understand that they are all different in this respect, or mostly different.
"on anti-crapware i usually give the user admin powers before i download the program ( say aaw) and install in the admin account and give it a shortcut"
2 Qs on this comment:
--- I'm not sure what you mean by "...
give the user admin powers...". Are you talking about a different process than switching users, or in other words, a different process than logging out of user and logging in to admin? Oh! Or is this the "right-click > Run as admin" trick you mentioned?
--- "...
give it a shortcut" Give it a shortcut...
from the limited user account?
Ok then, for whatever it's all worth, end of reply
Thanks for your patience,
especially mitch and ripley, and also everyone else who reads all this!
