Re: XP: Your Very own Low-Rights IE
said by BruceT  :I am not that well versed in XP admin rights and such but it seems to me that most people who have XP Home got it as an OEM that came with their computers when they bought them. I am sure that almost all of them are admins since that seems to be the way XP home sets the users up the first time they turn the system on. This means most "lay" people are open to exploits? Now from reading this, XP Home makes it difficult to use the system running it as a non-admin. Is that correct and if so what should the "average joe" home user do? Yes, people that are running as admin are open to exploits in the sense that any program they run as admin whether malicious or not can do anything it bloody well pleases, whereas, on limited accounts, there are strict limits to what can be done. A simple example: You execute a virus that wants to format your partition X. If you executed the virus as admin, the virus can do what it wants. If you executed it as a restricted user, sorry, no format allowed.
XP Home isn't so difficult to run as non-admin that I wouldn't recommend doing it. In my opinion, the average user should set up a non-admin account, and use that for non-admin tasks. Any problems with file permissions can be sorted out by booting in safe mode and editing the permissions there (in XP Home, the security tab appears in the properties menu only in safe mode). Some apps will probably be troublesome, but there's most often a solution for it.

Some apps will probably be troublesome, but there's most often a solution for it. The problem is that the additional burden of administrative tasks (and also how to carry out those tasks under NT) is inconvenient enough that most of the people I know outside of computers or IT don't do it.
In addition to the technical difference in security models between Win9x and WinNT, interacting with RunAs or discretionary ACLs is completely foreign to most users who upgrade from Win9x. (And too many Windows software developers.)
Some people have no problem with doing this and I always recommend running as non-admin. But for a large segment of users (particularly consumers with otherwise unmanaged systems) non-admin has to get closer to zero-maintenance, because that's often how much time many people spend on maintaining their systems.

| I agree that non-admin accounts as they are now aren't perfect, and MS has improvements to make, but I don't agree about the whole zero maintenance point. Non-admin accounts as they are now in Windows require some extra work, yes, but just how much extra work is required to constantly sort out malware problems that could have been avoided by not running as admin? According to my own (limited) observations, people actually have to waste less time on maintenance when running as non-admin.

| Its much less work, my anti-software updates on the system account, and if I really need to I can run as a program to do an admin task. The only real limitation is piss poor programing, anti-software that won't update on the system account, programs which require admin access like games which repeatedly install DRM software which causes problems with everything on your computer, etc...

said by Tuulilapsi :and MS has improvements to make So do software vendors, that is, constant writing to the registry should be done in HKEY_CURRENT_USER and the current user's Application Data folder instead of the program's folder.
So it seems Vista will ask for a password if a program requires more privileges to write somewhere. I fear this only encourages other vendors to continue this vile behavior even if MS recommends it to them as only a solution for legacy or poorly written apps.

| Agreed - software vendors, in particular security software vendors - should both advocate the concept of least privilege and write their programs to work properly with non-admin accounts. What I would like to see is MS getting really rough on anyone who churns out code that breaks with non-admin accounts. If you remember those lovely "This driver has not been certified for XP compatibility" warnings, perhaps something like that would be in order: "Warning: This software is not compatible with (fancy term like 'Windows Protected User Accounts' here). This software is poorly coded and may jeopardize the security of your system, and your socks. Do you still wish to proceed with the installation?" If anyone could get away with doing that, it's MS. What are vendors going to do? Start writing all their apps for other operating systems, as if the majority used them? It would work.

According to my own (limited) observations, people actually have to waste less time on maintenance when running as non-admin. Absolutely, I agree with you that it's less time consuming and less of a hassle to prevent problems rather than to fix them. And logically, it's a no-brainer.
But that's a "pay me now or pay me later" choice; a lot of people choose the latter, even if they aren't aware that they are making a choice.
Regarding what Microsoft has to do with non-admin accounts, I think Microsoft is mostly addressing third party applications that don't work. If it was just Microsoft apps, they could have fixed the individual apps without having to make many of the changes that are going into Vista. (They may be fixing them, anyway.) Day to day use of non-admin accounts has been possible on "managed" NT desktops for a long time.
In a way, the changes going into Vista are just another set of compatibility "shims" that Microsoft has to put into Windows to accommodate odd conventions in third party programming. In some cases, I believe those conventions were at least partly the result of a lack of documentation or "under documentation" of best practices for using some Win32 API functions.
