shtcut to restarting xp..


You can restart a Windows XP Pro and Home machine easily by creating a shortcut with following path. (Assume you installed Windows XP on your C: Partition) "c:\windows\system32\shutdown.exe -r -f -t 00" -r is for restarting the computer. -f is to force close all programs without saving. -t 00 is used to restart in zero seconds. i.e. as soon as you D.Click on the shortcut. You can log off from a Windows XP Professional or Home edition by running "C:\windows\system32\shutdown.exe -l -f -t 00". Also you can shutdown a Windows XP Home or Professional edition by running "c:\windows\system32\shutdown.exe -s -f -t 00". You always have to turn from the CPU after running this command. (Same with AT and ATX powered machines.) If you want to turn down power of ATX machine automatically, run "c:\windows\system32\tsshutdn.exe 00 /POWERDOWN /DELAY:00" This is used to turn off a server. Even though your computer will be
shutdown completely, this whole operation will take 30 seconds to finish. Even though you don't have networked computers attached to your computer, this works. 


1) Disabling Display of Drives in My Computer :

This is yet another trick you can play on your geek friend. To disable the display of local or networked drives when you click My Computer go to : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer Now in the right pane create a new DWORD item and name it NoDrives. Now modify it's value and set it to 3FFFFFF (Hexadecimal) Now press F5 to refresh. When you click on My Computer, no drives will be shown. To enable display of drives in My Computer, simply delete this DWORD item. It's .reg file is as follows: REGEDIT4 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explore r] "NoDrives"=dword:03ffffff 


2) Pop a banner each time Windows Boots :



To pop a banner which can contain any message you want to display just before a user is going to log on, go to the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WinLogon Now create a new string Value in the right pane named LegalNoticeCaption and enter the value that you want to see in the Menu Bar. Now create yet another new string value and name it: LegalNoticeText. Modify it and insert the message you want to display each time Windows boots. This can be effectively used to display the company's private policy each time the user logs on to his NT box. It's .reg file would be: REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon] "LegalNoticeCaption"="Caption here." 

3) Great trick Lock ur PC yourself



lock ur pc.. open notepad copy and paste the script below and save it .VBS extention
This wil create a shortcut.. run(click) it

set WshShell = WScript.CreateObject("WScript.Shell")
set oShellLink = WshShell.CreateShortcut(wshShell.SpecialFolders("Desktop") & "\LockWorkstation.lnk")
oShellLink.TargetPath = "%windir%\system32\rundll32.exe"
oShellLink.Arguments = "user32.dll,LockWorkStation"
oShellLink.Save

first select a folder for example i'll use a folder name movies in D drive D:\movies\

in the same drive u create a text file and type

ren movies movies.{21EC2020-3AEA-1069-A2DD-08002B30309D}

and save it as loc.bat

again u type in a notepad as

ren movies.{21EC2020-3AEA-1069-A2DD-08002B30309D} movies

and save it as key.bat

now in D drive u can see two batch files loc and key.. when u double click loc the movie folder will change to control panel and whn u double click key the control panel will change to normal folder..

there are two more different tricks in dis site to lock ur pc down in a unique ways.. donno where i have typed it.. !!!

4) Deleting System Options from the Start menu :



You can actually remove the Find and Run options from the start menu by performing a simple registry hack. Again like always Launch the registry editor and scroll down to the below key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer Right-click on the right pane and select New, DWORD Value. Name it NoFind.(To remove the RUN option name it NoRun). Double-click the newly create DWORD to edit it's value and enter 1 as its value. This will disable the FIND option of the Start Menu and will also disable the default Shortcut key(F3 for Find.) To restore the Run or find command modify the value of the DWORD to 0 or simply Delete the DWORD value.

5) Cleaning Recent Docs Menu and the RUN MRU :



The Recent Docs menu can be easily disabled by editing the Registry. To do this go to the following Key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer Now in the right pane, create a new DWORD value by the name: NoRecentDocsMenu and set it's value to 1. Restart Explorer to save the changes. You can also clear the RUN MRU history. All the listings are stored in the key: HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMR U You can delete individual listings or the entire listing. To delete History of Find listings go to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Doc Find Spec MRU and delete


6) Can u Delete Recycle Bin?


1 thing is 4 sure, delete option can be added 2 recycle bin...
the old registry thing will work out.....
* launch d registry...
* open HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder
* to add a rename and delete option, change the Dword attribute to 70 01 00 20
* refresh and reboot the system..... u r done.

PS: always backup ur data as well as registry b4 attempting 2 work on it if u r a newbie....



7) To change the icons used for specific drives in explorer


Open regedit by typing regedit into start->run

then navigate to 

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer 

now create a key(KEY not VALUE!!) called DriveIcons under Explorer...
now within DriveIcons, create another key with the drive letter you want to change (e.g.,HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons\K)...
create another key within the drive letter key called DefaultIcon...
now set the default String value equal to the icon you want to use. if you have a file that has more than one icon in it, such as a DLL file, use the standard
C:\full_path\icon_file.dll,n <file:///C:/full_path/icon_file.dll,n>) where n is the number of the icon within the file icon_file.dll...


~ c h e e r s! ~

change drive icons.....

first of all copy a icon file to the root of the drive.
example: c:\icon.ico

then create a file called: autorun.inf in c:\autorun.inf
then open that file and type the following:

[autorun]
icon=icon.ico

save and close the file.

now open my computer and resfresh.. and woh! icon changed....
you can apply to other drives too.

be carefull:

"autorun.inf" and "ico.ico" must be in the root of the drive.
example: c:\autorun.inf and c:\icon.ico.
same on the root.

ENJOY, this works on 98 too!!!!!!!!!!!!!!!!!!



8) Hacking windows SEND TO MENU


I know this is a very simple thing but the problem, as like many other issues, is the ignorance about it.

How often do you copy songs from a CD? Or some photos from a CD?

What do you do? You select the required files and do a CTRL –C. Open the destination folder and do a CTRL-V. Here is something you can benefit time from. Customize your SEND TO MENU. 

This sounds simple and you can do it in less than sixty seconds.
You can create your own BASKET.

First you’ll need access to hidden files. So change your view settings to make all hidden files visible.
Tools -> folder options -> view (tab) and select the show hidden files and folders.
go to parent drive:/documents and settings/(user name)/send to

Open up my computer and locate your most used folders.

Create a shortcut of the most used folders in SEND TO FOLDER.You can do this in a number of ways.

Right click -> send to desktop(create shortcut) and move the shortcut from the desktop to the SEND TO FOLDER

Copy the most used folder and go to SEND TO FOLDER and right click -> paste shortcut.

Also remember to rename the shortcuts to send to videos or send to potos. We don’t need confusion when we use the same later.

5. DONE

~ c h e e r s! ~


9) How to remove the shortcut arrow from the desktop ?



Open Regedit and navigate to the following key:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Shell Icons
Backup the key. More information.
In the right-pane, create a new String value named "29"
Double-click 29 and set its data to:
C:\Windows\System32\shell32.dll,50 (an empty icon)
Close Registry Editor.
Now,

Right-click Desktop, choose Properties
Click the Appearance Tab.

Click Advanced button.

Choose Icon from the drop-down list

Set it's size to 31 and press OK, OK.
The changes will be applied now. Repeat the above steps and then set the Icon size back to 32 (defaults). The above steps are required to force Windows to redraw the icons


10) The Complete list ! Can u Do it!


Try to create a folder in Windows with either of these names--
"con" or "nul" or "Aux" or "Lpt1".
Windows will not let u create ....

This s coz these refer 2 some well known ports....
-con corresponds to the console
-Lpt1 corresponds to printer and so on....

well dat was common but hw bt this ? Try these more

CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9.


TURN NUMLOCK ON AT LOGON.!!



NumLock does not toggle on by default (system-wide), even if you have it set in your PC's BIOS, because of XP's multi-user functionality. Guess Microsoft doesn't know everyone actually turns it on, which should be reason enough for what acts as "default"...
Anyway, you can hack the Windows Registry to change this behavior, or run a script at logon to turn NumLock on.
1. To enable NumLock through the Registry:
* Open Windows' Registry Editor (START > RUN, type "REGEDIT").
*. Navigate to HKEY_USERS\.Default\Control Panel\Keyboard.
*. Change the value for InitialKeyboardIndicators from 0 to 2.
2. To enable NumLock using a script, see this MS Knowledgebase article for complete instructions:
CODEhttp://support.microsoft.com/directory/article.asp?ID=KB;EN-US;Q262625
Option 1 is the quicker method, but if you have more than one user on your system and one or more don't want NumLock on (stranger things have been known of), then option 2 is the way to go since it allows you to only attach the script to specific users.

REMOVING SERVICES DEPENDENCIES.!!


This will allow you to disable a service or uninstall it from your system without effecting another service that depends on it. Here's how you do it
1. After you have set your services the way you want them and you have disabled/uninstalled something that another services depends on, run "regedit"
2. Under HKEY_LOCAL_MACHINE\System\find the service that will not function, do to another service being disabled/uninstall (found in ControlSet001\Services, ControlSet002\Services, and CurrentControlSet\Services)
3. Once you have found the service right-click on the string value, "DependOnService,"and modify
4. You should now see a list of services that it is dependent on. Simply delete the service that you have disabled/uninstalled
5. Restart your computer and your ready to go Disclaimer REMEMBER TO BACKUP YOU REGISTRY FIRST I'm not totaly sure if this will have any negative effects on your system. I used this method after uninstalling "Netbios over Tcpip" from my system completely, so that my Dhcp service would function and I have had NO negative effects on my system.

Recently when I tried to copy some files to my mmc using card reader it showed me some error saying the disk is write-protected. Remove the write protection or use another disk.
It was working fine before. I have used this card many times before but it never gave any error and suddenly it started showing this error. After going through some forums I came to know that it happens because of write protection notch but there was no such notch or switch on my card.I kept on searching on more forums and after some time I found one solution to this problem. Follow the steps given below if you are also facing the same problem.
  1. Run Registry Editor (regedit).
  2. Navigate to the following registry key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
  3. Right click on control and create new key.
  4. Name it as StorageDevicePolicies . (Copy and paste it from here if possible)
  5. Now click on StorageDevicePolicies and in right side pan right click and select create new dword and name it as WriteProtect.
  6. Double click on it and set its value to 0.
Now restart your machine and try copying some files to your card.


Increase the life of ur dvd rom.

This is an interesting one!!!

This is for those who watch movies on their computer's dvd rom drive!!!
There is a software called dvd idle pro which can really increase the life of your dvd drive. By using the Smart Read-ahead Cache,
DVDIdle saves DVD data which will be played soon onto the hard disk cache or RAM cache, and
then feeds it to DVD player.
This allows the DVD drive to rest.

For example:
a 6X-speed DVD drive will only work for 15 minutes when you are watching a 90 minutes DVD
movie.
here is the link: http://www.dvdidle.com/download/DVDIdlePro59.exe

SPEED UP UR "RAM".. PLAY BETTER GAMES...

1. To speed up your windows or to increase RAM virtually,
Right click on My Computer
>> Properties
>> Advanced
>> Performance - Settings
>> Advanced
>> Virtual Memory - Change
Keep the initial size same as recommended and maximum size double of it then restart your system.
It will improve speed of windows and you can play some games which require higher RAM.


2. When a window is active, press the F11 key of the keyboard to get the biggest window possible and press F11 again to restore it.

FOLDER OPTIONS ARE MISSING

Many times we find that the folder options missing in windows explorer
