Low transfat and low carb diet for you pc
or How to optimize Windows XP for the best performance.
Compatibility: Windows XP Professional/Home. Should be OK on Windows 2000, some options/features will not present.
Purpose: Unfortunately, starting from Windows XP, most of the software and hardware manufacturers adapted a habit of diverting
user s attention and time towards their own goals  collecting personal information (e.g. preferences, habits), advertisement, etc.
This article is my personal answer to this unprecedented corporate takeover.
The following set of instructions will help significantly to improve Windows XP performance without costly upgrades.
To shorten this article and save your time, I ve decided not to go into theory behind suggested configuration changes. If you require
additional information, please search Windows Help and Support (Start -> Help and Support) or Internet. List of related links posted
at the end of the document; And downloadable/printable version (in Adobe Acrobat format)  at the top.
Your Comments and Recommendations are welcomed, but I can t promise to respond to every message.
Warning: If you would like to be able to undo the described changes, please use System Restore utility (see Windows
Help and Support (Start -> Help and Support)) to create a restore point first.
1. Clean Startup Folder (Start menu)
Right-click Recycle Bin, and select Properties.
Under Global tab uncheck Display delete confirmation dialog option (Pic.1).
Pic.1

Pic.5
All items that you see start automatically whenever you start computer. Delete all unnecessary entries by right-clicking it, and
selecting Delete.
Note 1: Removing items from the Run folder will not remove the corresponding program from your computer. It will simply prevent
the program from loading automatically, and running in background, consuming valuable resources.
Now, repeat the same procedure for the Run folder under HKEY_LOCAL_MACHINE (Pic.6):
Pic.6
Browse to HKEY_LOCAL_MACHINE -> Software -> Microsoft -> Windows -> CurrentVersion -> Run. And delete everything that you
don t want to load automatically (see Note 1). As you see from Pic.6, I have a few items in Run folder. They represent Autoprotect
services of my Norton Antivirus. You may have other antivirus/firewall applications loading trough Run. I wouldn t recommend
removing antivirus/firewall from Run folder. Everything else can (and should) go. Restart computer.
3. Remove useless programs (Add or Remove Programs)
Click Start, point to Settings, and click Control Panel.
Double-click Add or Remove Programs icon (Pic.7)

applications (MS Office, MS Works, Quake III, Unreal Tournament 2003 and almost everything else) will run just fine (well& , faster).

It s very easy to disable/enable Virtual Memory. Try both options, and determine the one that fits your personal preference.
See Windows Help and Support (Start -> Help and Support) on how to disable Virtual Memory.
Run Disk Defragmenter after disabling/enabling Virtual Memory.
Restart computer.
10. Enjoy!
Afterword:
This may seem simple, but don t keep your computer on when you re not using it. In 2002, a Cornell University study calculated that
the US could switch off seven power stations if TVs, videos and computers were not left on standby.
Even if you are yet to lose your job, and not very concerned about your electric bill, and rising number of countries we need to
 liberate to secure energy resources, consider this:
Windows is not a none-stop operating system. Not only it is leaking system resources, it also has a tendency to keep some
programs running in background even though you closed them.
If you have an "always-on" internet connection, such as a DSL or cable, keeping your box on 24x7 will tremendously increase your
chances being hacked or infected.
