First, and most important let me remind everybody, make backups before you try any adjustments to your os, or registry, ie, please create restore points or registry backups before you try each one of these ideas!

MY PERSONAL ORDER, FOR TURBO CHARGING MY OS, AFTER REFORMAT
1) A restart button on your desktop:

1. Create a shortcut (Right-click on desktop, select New > Shortcut). 2. For location, type the following:

shutdown -r -t 0

3. Click Next, enter a name for the shortcut ("Restart” is appropriate), and click Finish

2) Since I use the system restore as my registry backup, and I backup often, I put the system restore shortcut on my desktop also, the target is %SystemRoot%System32restorerstrui.exe

3) I love device manager on my desktop, target %windir%system32mmc.exe c:windowssystem32devmgmt.msc
I’m also in the registry a lot, so that’s on the desktop too, target C:WINDOWSregedit.exe

4) I turn off all the startup programs possible, in msconfig.

5) I turn off all the services possible; go from administrative tools, to services, turn to manual or disable whatever you can, go to http://www.blkviper.com for ideas on what you can safely turn off.

6) I increase the icon cache, On XP the Max Cached Icons is set too low,
to changed this got to regedit,HKEY_LOCAL_
MACHINE-Software-Microsoft-Windows-currentversion-Explorer

in the right window, double click max cached icons, type the value 8192.
If you don’t have this, open up your registry and make your way here:-
HKEY_LOCAL_
MACHINE/Software/Microsoft/Windows/currentversion/Explorer
in the right side, right-click a blank area and choose “New” “String Value” and call it
Max Cached Icons
Double-click this new Key and type the value
8192
into the box
P.S.
If you want to try the DWORD version, follow the above but instead of making a new String Value, you should make a “New” “DWORD Value” and call it
MaxCachedIcons
and give it a Value of
2000 in Hexadecimal, or
8192 in Decimal.
then reboot you should see a big speed boost icon load, and opening folders.

7)I can’t stand logging in, I do it automatically,
Enabling/Disabling Automatic Logon
1. Click Start on the Windows taskbar, and then click Run.
2. In the Open box, type “control userpasswords2″ (without quotes),
and then click OK.
3. In the dialog box that appears,
You’ll see: “Users must enter a user name and password to use
this computer” check box.
Enabled will require users to logon, disabling will make XP
automatically logon to the Administrator account.

8) Xp does not manage the page file very well, to set it correctly, I follow allans advice,
To get to the Paging File Settings: Control Panel / System / Advanced Tab / Performance (Settings button) / Advanced Tab / Change Button

If you have more than one hard drive, put it on the fastest one. If you have only one hard drive with multiple partitions, put it on the largest partition.

XP sets a page file on each partition by default, you only need one. Follow the above instructions on where to put it, then disable the others.

The size of the Paging File should be approximately 1.5x (one and one-half times) your installed ram. That is, if you have 512 meg of ram, then the page file should be approximately 768 meg.

This “static” setting will minimize fragmentation of the page file.

9) I eradicate the messenger, the easiest method; Click Start / Run, and paste
RunDll32 advpack.dll,LaunchINFSection %windir%INFmsmsgs.inf,BLC.Remove

Press ENTER
Restart Windows

10) Of course, I disable balloon tips; from regedit;
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced
then set the value of ‘EnableBalloonTips’ to 0.

Or if you have TweakUI, disable tips is in tat program
