How to change
settings in a deep freeze enabled computer (date/time)
Deep Freeze is a software, mostly used in cyber cafes to freeze or make
hard drives unable to accept installations, changes and generally any settings
made to the computer in which it is installed on. In most public computers, for
example: Cyber cafe computers are public computers and most have Deep Freeze
installed on them to clear private data of every user, every time the computer
powers off.
However, using a Deep Freeze to prevent access to unauthorized persons
is important and should be taken to consideration.
How Deep
Freeze works?
The function of Deep Freeze software on a computer is to make sure
everything about the previews user is cleared before others can access the same
computer. For example Emails, Passwords, Browser history, System settings,
Saved websites, Bookmarked websites etc.
If you saved a good number of websites on a Deep Freeze enabled
computer, there is high possibility that you will not find them after the
computer restarts, no matter if you saved or not. That applies same with other
settings and browser histories in the computer. If you most have noticed that
every public or cyber café computer hardly suggests names of web sites as you
start typing them, with reason being that the previews session has been cleared
by the software and you can’t gain access to files of the previews session.
Remember that these settings are only cleared if the computer powers
down/restarted before it is being used again. If I may advice or remind cyber
café owners that there are a good number of software that allows you to
configure either if a computer should be restarted in every session timeout
(when users time runs out) or not. Assigning a restart in every session timeout
is best and should increase a high level security in your business place.
What if I want to install a program?
Even the most complicated machines has their own way of getting through
and making changes, best suiting your want. Same with Deep Freeze, there is
also a means of installing programs even with the Deep Freeze installed on the
same computer. There are many types of software that plays such rolls, but I
will be talking meanly on Deep Freeze, (Faronics software). There are also
others like Returnil 2008 and maybe the latest versions are available, but so
far Faronics sotware (Deep Freeze) is most common and does work well.
Before you even start anything, you have to disable the software to
liberate the computer from its frozen mode. When the computer is unfrozen, you
are allowed to make changes to the computer as much as you want, with no fear
of losing them in case the computer powers down, unless you did not save. To disable Deep freeze for program
installation, press and hold ctrl + alt + shift + F6 and the login windows pups
up. Login with the password you provided during or after installation. Select
Boot Steward, then click apply and reboot button, confirming a warning message
will reboot the computer and make it free for possible changes to be made. You
are free to install, but make sure there is an X on the Deep freeze icon in the
system tray. Remember to go through the same process and choose “Boot frozen “to
enable it again.
Do I need
that process to change system date and time too?
Changing date and time in a frozen computer could be very difficult at
windows level, since the frozen computer will not be allowed to accept any
changes till its set free. Well, there is a difference between changing
something that won’t stay after a restart, and trying to change what cannot be
changed or trying to change what you are not given access to even for a restart
or not. What am I saying? The Deep Freeze will not stop you from accessing the
date and time settings area, but the difference is what will happen after the
computer goes off and on. Changing system date and time every times the
computer boots could be tiring and you may sometimes forget. However running a
computer with wrong date and time could course several problems to your
computer, running in the box and either with or without your knowledge.
including the ones you see physically, for example. If you have hard your
computer scheduled to scan or update the whole system every 4PM, knowing fully
well that the computer freezes during this process and allow you less
privileges to work, even playing music could be difficult. You have the
computer set to perform these tasks at that time because you know you’re always
free and might not be working on the computer, meaning you understand the
stress the computer goes through while it scans or update and at the same time
you use. But now, what if the system time is wrong, and starts performing these
tasks right before you are done, maybe still at 12 noon in the correct time
zone? It’s annoying as compared to my own case when my computer freezes, I just
fell like heating till it gains stability, and of course that’s not the right
step to take, but simple (CORRECT DATE AND TIME) Some problems encountered as a
result of wrong date and time could be “Un-trusted connections”. When you are
working online, the internet and computer time work in hand, to make sure the
same day on computer should be the same with the internets. Each and every web
site is certified and made easy and trusted for you to browse through your
computer, with the help of date and time.
If your computer date and time displayed 4/10/2012 instead of the current
date, each web site you visit compares the current sever date and time with
yours, and if it’s different from each other, the browser things the
certificate of the site your viewing has expired and will try to prevent you
from using web sites with outdated certificates due to wrong date and time. We
will know more about site certification in the upcoming articles.
I know I almost went off the whole deal, but I hope it did help explain
the outcomes of wrong system date and time. Diving back to our main target (Do I need that process to change date and
time?), I will show you a very easy and simple way of changing date and
time without even the interest to know if there is any deep freeze installed or
not.
One good
thing
Deep freeze only functions at windows level and cannot affect any changes
made in BIOS setup or before the system boots.
Change date
and time in system BIOS setup
With the system BIOS setup, you can make several changes to your
computer without any fear or awareness of whether there is a deep freeze
installed in the computer or not. In the system BIOS, you can change or correct
date and time, right before the system boots. Settings made at this level are
never cleared by the Deep freeze, with reason being that the Deep freeze only functions
at windows level immediately the computer boots. But because system setup is
accessed before the computer boots, the Deep freeze is denied access and cannot
be in charge of anything at this level.
Take for instance; if the Deep freeze had powers over the whole system
even in BIOS then formatting a computer with Deep freeze installed would be a
big problem. If you noticed, then you most have found out that each time you
save changes in the system setup, (bios) the computer restarts and starts
booting afresh, following instructions as assigned in the previews setup, and
if Deep freeze where to work through the whole system then those settings will
be lost after the computer restarts, but because it’s not that way you are able
to format a computer by assigning the first boot device to be the CD ROM without
any fear of losing when changes applied restarts the computer, so go on and
change your date and time.
Good luck.
