Ok now some of my triks :
(1) To change start button's text:
Backup the file explorer.exe first, and then edit it in dos
mode (click start click shutdown clcik restart in dos mode)
for windows 98. Note : If you don't have windows 98 you can
either boot from a floppy, cd or do this from another operating
system's dos. At the Dos change to the directory where is the
explorer file usually c:\windows and type the following command
Edit /70 explorer.exe
Then Search for Text (start) it will be written like this
( S t a r t ) Then press the insert key on your keyboard and
take the cursor to word (S) And type your desired word and
press the right arrow key and then type next word and repeat
this procedure till the last word..... Note : You can't write
more than 5 letters but if you want to write less than 5 letters
then when you have finished your work take the cursors on the
last word(s) which you want to remove and then press space bar.
If you can't search for the word (start) here is the description
of lines and columns of some windows !
Windows 2000 (Line 3236 Col 56)
Windows Xp (Line 3814 Col 25)
Windows 98 (Line 2390 Col 49)

(2) Sorcut without arrow :
First
creat a blank icon using paint.( How : Open paint brush
and then click image attributes type 32 in both boxes and
click o.k then save the file as blank.ico ) Then open
registry editor by typing regedit in run box and go to
Hkey_Local_Machine\software\microsoft\windows\currentversion
\explorer\shell icons right click anywhere in the right pane
and from the new menu select string value type "29" (without
quotes) as the name of the value and then double click on it
and now fill it with the path of that icon for exp "c:\my
dcouments\balnk.ico" with quotes. Now you've done but you'll
see nothing happens actually you need to refresh icons (How :
right click on desktop select properties and then go to
appearance tab and from the drop down item list select icon
and then reduce there size by 32 to 30 and then back to 32 now
you've finished. No shortcut arrow haan!
(Note : for windows 98, Me, 2000 and may be Nt, 95 but not for windows xp)

(3) Just for fun(1) :
Try this naughty trick on your friends PC. Close all
the open applications. While you are on the Desktop,
press Print Sceen key. Open Paint and then paste the
captured image. Save it as BMP, right - click on the
desktop and change the wallpaper to the newly saved image.
Go to the "Web" tab of the Display propeties dialog and
turn on Active Desktop. Make sure that the "Hide icons
when desktop is viewed as Web-page" is turned on. From
now on, your friend wont be clicking an application icon
on the desktop, just a picture of it. See their face when thet happened!

(4) Just for fun(2) :
Open MS DOS Promt and then go to the C:\Windows\Desktop
directory. Normally you only need to type CD DESKTOP and
press enter. Type (for exemple): MD 2002 VIRUS .Use the
space bar between MD and 2002, but between 2002 and VIRUS,
hold down ALT key and enter the number 255 on your numeric
keypad. This will create the space character that cannot be
removed from Windows shell (Explorer). Thats it. Now wait
until you see your friends face when they cannot remove that
"Virus" folder from desktop.
Just in case your friend panic and ask you for help to
remove that "Virus", here are the steps: repeate the
above steps but use the RMDIR (Remove Directory) command
instead of MD ( Mke Directory )

(5) Restart link on your Desktop:
To create the Restart link on your Desktop do this:
Right click on Desktop and create link for
C:\Windows\RUNDLL.EXE user.exe,exitwindowsexec.
Use the space between RUNDLL.exe and user.exe,exitwindowsexec.
Now you can restart you PC not from start menu...

(6) Shut Down link on your Desktop:
To create the Shut Down link on your Desktop do this:
Right click on Desktop and create link for
C:\Windows\RUNDLL.EXE user.exe,exitwindows.
Use the space between RUNDLL.exe and user.exe,exitwindows.
Now you can Shut Down you PC not from start menu...

(7) This is a system cheat.
now follow this steps
first create new shortcut.
C:\WINDOWS\RUNDLL32.EXE
& at the end of the line add this
' user,exitwindows'
so it will look like this
C:\WINDOWS\RUNDLL32.EXE user,exitwindows
when you run this file your computer will be
shutdown without asking you.

(8) Windows cheat:
every time when you are asked for restarting your
computer or when you want to reboot or restart your
computer(opearating system must be windows:any version)
just keep 'shift' key pressed & click on restart option
& then press 'ok'.
only windows will be restarted.
you won't get any startup options.
but you must keep pressed 'shift' key.

So .. i belive this is it ... One more thing you can customize your windows very simple just follow this link : http://wincustomize.com some interesting stuff !
