BOOT CAMP 526 (27/05/08)
User Accounts, and Password Recovery part 1
only thing worse than a rickety computer is one that is clearly firing on all
cylinders, but stubbornly refuses to let you access your files because you’ve
forgotten your password. Actually there is something worse, being asked for a
password when you didn’t (or don’t remember) setting one…
to the often confusing and sometimes frustrating world of Windows accounts and
passwords. Over the next few episodes of Boot Camp we’ll be delving into this
mysterious and murky realm, and – what many of you have been asking for – some
advice on what to do when you are locked out of your computer.
first, a brief guide to user accounts in Windows XP and Vista. In fact there
are a number of significant differences between the two operating systems, and
also within the various ‘Home’ and ‘Pro’ versions, and we’ll look at some of
them as we go, but the basic concepts are the same.
the ‘first run’ Windows asks you to enter your name and organisation and create
a password for the all-important Administrator account. There are actually
three types of accounts on a Windows XP PC, the aforementioned Administrator
plus Limited Users and Guests, each with different access rights and
privileges. See also this week’s Top Tip.
Administrator is the boss of the computer, the Kahuna, the Big Cheese and the
person who decides who else uses it. He or she is also the only one who can
make changes to critical system settings, install software and hardware and
much more besides. Windows XP allows more than one User account to have
Administrator rights, sometimes without asking and generally speaking this is
not a good idea. On a shared machine only one person should be in overall
charge or chaos will surely ensue. Vista and Windows 7 are different, Users can have a range
of Administrator rights, there’s also a hidden ‘Super Administrator’ account
and we’ll look at that next week.
frequent users of a shared computer, including the Administrator, should have
their own individual User account. Each User can then customise Windows with
their own background images, desktop layout, screensaver and email account as
well as do all of the usual things, like access shared files (Documents,
Pictures, Music etc.), write documents, surf the web, create their own
Favourites lists and use most of the software on the PC. What they can’t do is
interfere with critical system settings, they are limited in the programs and
hardware they can install and they cannot access other Users protected files.
If required the Administrator can set even more restrictions on a per-user
basis. However, for most PC users this type of account gives them the freedom
they need whilst protecting the system core, and other users.
XP does not create a Guest account automatically but it’s easy enough for the
Administrator to set one up, and there’s no need for a password. Guest accounts
are meant for occasional and one-off users of a computer and provide only
limited access to the computer. Nevertheless, Guests can still surf the web,
write documents and so on but just about everything else, including other Users
protected files are strictly off limits.
speaking it works reasonably well (or at least it did in the very early days of
Windows XP) and it means that on a typical family PC, for example, one or both
parents will manage the Administrator account but each parent will also have
their own Limited User account, so they can use their own background, desktop
and screensaver, operate their own email accounts and keep their messages and
documents separate and safe. Additional Limited User accounts are assigned to
each child, and if one of the kid’s friends wants to use the computer they can
do safely so via the Guest account.
has their own personal slice of Windows and in theory no one, except the
Administrator can mess things up. In practice there are dozens of things that
can go wrong but the big problem, with Windows XP, is that it is far too easy
to assign Administrator rights to Limited User accounts. This makes the
computer much more vulnerable to accidents and it compromises security.
launch of XP in 2001 also coincided with the explosive growth of broadband and
the emergence of ‘Malware’. This is malicious software that gets into a
computer, silently and stealthily via pop-ups on web pages. All a user has to
do is innocently click on a button and hey-presto, the whole computer, and not
just one User’s part of it, is infected.
big change in Windows Vista is User Account Control (UAC) and this seeks to
prevent mishaps and tighten up security by making sure that only a User with
Administrator rights can install software, drivers or services that affect the
whole system. It also makes it much harder for malware to get into the system.
UAC also has an extra failsafe and any attempt to change system files generates
an on screen message that requires consent from a User with administrative
rights, so changes cannot be made unwittingly or by accident. . Well, that’s
the basic idea anyway but there’s much more to it (see this Microsoft
article), and a lot that can go wrong…

it assumes that you are the sole user and usually – but not always – that is
the last time you’ll be asked for a password. If you do create one choose
something that won’t be easily guessed by someone who knows you. That means not
using your own name or that of you partner, children, pets, your phone number,
street or house name and so on, at least not as-is. One way to create a
memorable password out of a familiar name or word is to reverse or jumble the
order of the letters. For example, if your cat’s called tibbles, your password
might be ‘selbbit’. To make it even stronger add your house number to the beginning
or end. When you create a password Windows asks you to enter a ‘hint’ (more
about that in Part 3) to jog your memory if you forget it; in this case it
could be something like ‘catback’ or ‘pussrev’.
