Congratulations for your new acquisition !!
First thing you must do is to keep some kind of order relating to
where you save the downloads, even you must know where the partial
downloads are. This last thing is in the case that the partial
download be abandoned and you have an unuseful file wasting several
megabytes from your hard disk.
With the above in mind the download folders must be revisited once a
week to delete the unnecessary downloads (like music that you don't
like after you heard it, or programs tested and/or discarded, etc.).
Keep the downloads organized by categories for quick find for use them
and delete them.
Is it always a good idea to save to a CD or DVD the download folder in
a regular basis and then empty the folder at the computer.
Regarding the installation and desinstallation of demos and trials
versions this could result in a damaged or unnecessary high size
To avoid this there is a free program that check the registry and help
you to keep it clean, this program is RegSeeker:
Download it from here:
Note: If after a cleanup, your Add/Remove control panel doesn't work
(release 1.05RC3), just download this reg file and merge it into your
Click here to download it(FixAddRemove.reg):
Run it once a week and using the "Clean the Registry" option at the left frame.
The following page gives you an idea on how to use this powerful program:
"How to clean the Windows registry after uninstalling old Java
versions - AzureusWiki":
Another option is to clean the registry with RegCleaner (this tool
works manually, you must search the bad registry entries by yourself):
Install and run this program and them at the Software tab search for
references to the trials (at both columns Author and Software), select
all the references found and then use the remove selected items
With RegCleaner you will be able to get rid of those old and obsolete
registry entries created by the trials, for help on using this program
Note: If the viewlet is too wide, you can use these Keyboard
shortcuts: PAUSE to stop it running on its own, the RIGHT ARROW to
move forward frame by frame, and ALT F4 to close the viewlet window.
Your computer is also 24/7 connected to the Internet, so you must
protect it from net attacks, you will need a firewall for that if you
are not using Norton Internet Security suite. I recommend you a free
one, it works very well at home computers and it is easily
customizable in the case that you need to open or close some specific
port or need to block an application, this program is Zone Alarm:
Download it from here:
"Zonealarm is one of the more popular free for non-commercial use
firewalls. There are many reasons for this, the main being the
detailed installation and configuration tutorials that come with it.
This software is also ready to use immediately after it has been
installed, making it great for novice computer users.":
From "Security Reference Guide - Free Security Software, Part 2":
One more thing needed is a tool to clean the temporary files and
folders and also all the stuff that comes from the Internet and is
keeped unused in the computer. For this the better option is CCleaner:
Download it from here:
For guides on how to use it see:
"CCleaner: Get the Crap Out of Your PC - WinPlanet Windows Software Reviews":
"CCleaner - Quick Tour":
"Clean & Protected - CCleaner Scan tutorial":
Two more tools will be needed to protect your computer:
This tool is for prevent the installation of pestwares.

Hijackers, and Malware":
The other one is his brother SpywareGuard:
A real-time protection solution against spyware.

Finally I recommend you to see the following question, that I
answered, related to how to make and use a disk image to restore to a
previous good system configuration when it is necessary:
"Google Answers: Windows XP backup with drivers":
At this point my recommendation is a paid software, Norton Ghost, that
is the one that I use, but the free choices works very well according
to several reviews and some friends opinions.
Now you are ready to work, but I suggest you to take a look to the
following pages for additional and useful info:
"Simple and easy ways to keep your computer safe and secure on the Internet":
"Security Reference Guide - Home User Security":
Go through the "Next Section" links until the end, it is a large
article. See specially the "Free Security Software" parts 1 and 2
