Also, you should (MUST) place a password on your account.

How?

Start | Control Panel | User Accounts | Choose "Owner" (or what ever account you named it above) --> Select "Create a password."

That's it

(Note: Reference @ http://www.uksecurityfocus.com/husdg/windowsxp/renameadmin.htm,
	           http://support.microsoft.com/?kbid=279783                       )

Delete temp folder upon startup -
have a copy of the file cleanXP.bat (from your bckup CD or from www.geocities.com/wwf_tomie16),
then copy it to the startUp folder.

Delete the Links folder from Favourites -
1). HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Toolbar
2). Look for the key "LinksFolderName", and delete the value "Links".
3). Delete the folder "Links" from Favourites.

power management -
1) Standby mode
2) Suspend-to-Disk mode (STD)
3) Suspend-to-RAM mode (STR)
They should be able to be configured under Control Panel. Try to find where Power Management
is. They can also be configured using BIOS, but it's not recommended.

Practices -
1) Get at least TWO anti-spyware softwares, such as Spybot & Ad-aware,
   and probably SpywareBlaster as well.
   (1.1) Perform scan and check for updates at least once a week
   (1.2) In addition, get CWShredder @ www.spywareinfo.com/~merijn/downloads.html
 
2) Get at least one antivirus software, such as Avast; and optionally,
   at least one online virus scanner, such as TrendMicro @
   http://housecall.trendmicro.com
   (2.1) Perform scan and check for updates at least once a week 
         (some softwares will have automatic updates)

3) Keep a log of what has been disable/enabled

4) Create restore point(s) before installing anything

5) Disable System Restore when suspecting virus or spyware threats,
   which you'll scan for, and remove if possible. You can re-enable
   System Restore once you're certain that your PC becomes clean.

6) Perform bckup at least once a month. The most convenient way is
   to keep an installation file for each software, and keep a zipped
   version of non-softwares (such as picture or doc files).

7) Do not login as Adminstrator unless it is absolutely necessary.

8) Perform disk cleanup at least once a week.

9) Perform ScanDisk, followed by Disk Defragmenter every two weeks.

10) Run System File Checker every two weeks.

11) Remove any unnecessary windows components.

12) Check for windows updates once a week. Look for "critical updates" first, which
will fix the most serious holes. Wait for a week or two after SPs and patches come out.
Recommend to get patches with uninstallers.
Do not choose the automatic windows update option.
(Note: patches for realplayer can be found @ http://service.real.com/realplayer/security/
However, realplayer is known to have spywares. Any site associated with it is not
guaranteed to be safe, so visit that website at your own risk!)

13) Turn off any unneeded services.

14) There is an issue of random connection drops for the wireless network. This has
nothing to do with the router. The problem comes from the Wireless Zero Configuration
in Windows services (run -> type "services.msc" without quotes). Go to D:\WRT54GS\Help
for more details. It has been claimed that Microsoft is aware of the problem and might
provide a fix soon.
