Here are the Game Cheat for some of the windows game.

Minesweeper

Secret – Reveal Mines

Instructions – Minimize or close all running applications. Launch Minesweeper, then type xyzzy. Next hold down either shift key for one second. Now when you move the mouse cursor over a Minesweeper square you will see a tiny white pixel in the top left corner of your desktop screen. This pixel will change to black when your mouse moves over a mine. You may need to change you desktop background to a solid color other then white or black to see the pixel.

Pinball

Secret – Extra Balls
Instructions – Type 1max at the start of a new ball to get extra balls.

Secret – Gravity Well
Instructions – Type gmax at the start of a new game to activate the Gravity Well.

Secret – Instant Promotion
Instructions – Type rmax at the start of a new game to go up in ranks.

Secret – Skill Shot
Instructions – Launch the ball partially up the chute past the third yellow light bar so it falls back down to get 75,000 points. There are six yellow light bars that are worth a varying amount of points:

First: 15,000 points
Second: 30,000 points
Third: 75,000 points
Fourth: 30,000 points
Fifth: 15,000 points
Sixth: 7,500 points

Secret – Test Mode
Instructions – Type hidden test at the start of a new ball to activate Test Mode. No notification will be given that this is activated but you can now left-click the mouse button and drag the ball around.

Secret – Unlimited Balls
Instructions – Type bmax at the start of a new ball. No notification will be given that this is activated but when a ball is lost a new ball will appear from the yellow wormhole indefinitely. Once this is activated you will be unable to activate other secrets without restarting

FreeCell

Secret – Instant Win
Instructions – Hold down Ctrl + Shift + F10 during game play. Then you will be asked if you want to Abort, Retry or Ignore. Choose Abort, then move any card to instantly win.

Secret – Hidden Game Modes
Instructions – In the “Game” menu choose “Select Game”. Enter -1 or -2 to activate the hidden game modes.

Solitaire

Secret – Instant Win

Instructions – Press Alt + Shift + 2 during game play to instantly win.

Secret – Draw single cards in a Draw Three game

Instructions – Hold down CTRL + ALT + SHIFT while drawing a new card. Instead of drawing three cards you will only draw one.

Infinite Points

In the Windows XP version of solitaire, draw from the deck at least twice. Hold control and drag a card down from the deck. Click the “A” key and then let go of the left mouse key. You will get 10 points for this. Continue doing this for infinite points!

Infinite points trick II

To do this trick, finish a game of solitaire with the time bonus option on. The cards will start bouncing. Click on the solitaire screen and the play again box will pop up. Select no, so the solitaire screen is just blank green. Use the instant win cheat (Alt+Shift+2) and you will recieve the time bonus you got last game will be added to your last game’s score. For example, if your time bonus was 5000, and your final score was 6000, after using this glitch, you will have a score of 11000. This glitch can be used as many times as you want.

Registry hack which will allow you to see your opponents’ cards

Launch REGEDIT.EXE and navigate to HKEY_CURRENT_USER\Software Microsoft\Windows\CurrentVersion\Applets\Hearts.

NOTE: You may have to create the Hearts key under Applets In the right-hand pane, create a new String Value. Immediately rename it to “ZB” (without the quotes); give it a value of “42″ (again, sans quotes).

The next time you are in a game of Hearts, press CTRL + SHIFT + ALT + F12.

Remove shutdown from start menu and also from all other possible options Or hide shutdown from start menu.

This tool is a inbuilt tool present in windows XP, just like msconfig. So you got to execute this command using run.

1 . Start ->run and type gpedit.msc.

The gpedit stands for group policy and you can do wonders using this.

2. User configuration -> administrative Templates -> start menu and taskbar –>

3. This option opens up a pane on the right hand side. Identify the option named- Remove SHUT DOWN on the start menu .

4. Double click Remove SHUT DOWN on the start menu option.

5. A small screen pops up and you may like to read about the explanation in the EXPLAIN TAB before you change the settings.

6. Just change the radio button TO ENABLED and say apply.

7. DONE. No need to log off or restart the system. (You may however have to find a way to restart your system.)

8. This option disables the log off option from the system. From the start menu, also from the life saver – three buttons CTRL – ALT – DEL options.

This option goes well with the HIDING THE LOG OFF FROM START MENU… (To shut down your system:-without using shut down menu) The solution is that you can switch user through task manager (alt+ctrl+del) or by pressing win key+L where you get the option to turn off your computer /restart/standby.

Or you may create a shortcut using this shortcut location:

To shutdown your system %windir%\system32\shutdown.exe –s

To restart, you can use this shortcut %windir%\system32\shutdown.exe -r

Many of us are really fond of videos and watch videos at YouTube or Google Videos.  Of course you prefer to watch good quality videos at YouTube than those worse videos.

There is a small trick that will do all the wonders, and now you can always get good quality YouTube videos.

Step1: Click to video that you want to see, the link will display on Address bar.
Example:  http://www.youtube.com/watch?v=Ne1l6VNkuLM

Step2: Add &fmt=6 to the end of that string.
That address like:
http://www.youtube.com/watch?v=Ne1l6VNkuLM&fmt=6

Optional Step: To get more quality YouTube video
.Add   &fmt=18 to the end of that string, you will have the best quality video with direct download link !

Example:
http://www.youtube.com/watch?v=Ne1l6VNkuLM&fmt=18
Note: Appending &fmt=6 to the URL delivers a 448×336 resolution version of the video and appending &fmt=18 delivers a even better 480×360 resolution version.

Many of us sometimes find the folder options missing in windows explorer.

Here’s the solution:-

Open Run and then type "gpedit.msc".
Now go to User Configuration > Administrative templates > Windows Component > Windows Explorer.

Click on Windows Explorer you will find the 3rd option on the right side of screen "Removes the Folder Option menu item from the Tools menu"

Just check it, if it is not configured then change it to enable by double clicking on it and after applying again set it to not configured.

In old days of Windows 3.1 when you could open up the Win.ini file in a text editor and remove an item from the RUN= line to disable it from running at startup.

With Windows 9x and above, the Win.ini file became less useful because 32-bit programs were set to run at startup from within the Registry instead.

One way to selectively disable programs from loading at startup is to use MSCONFIG (from the Run command) to
deselect certain items.But this leads to selective Startup which may cause problem.

Another way to remove them is to edit the Registry directly.

Consider the following locations:
HKEY_LOCAL_MACHINE\Software\ Microsoft\Windows\CurrentVersion\Run

for applications that start up for all users

HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\Run

for applications that start up when the current user logs on

Remove the entry for a program by right-clicking it and selecting Delete to prevent it from loading

When Windows XP is first installed it requires you to enter at least one name of a user who will access the computer.

Once you create this name the default Administrator account vanishes.

To access it, press Ctrl-Alt-Delete twice at the
Welcome screen to retrieve the standard Windows XP logon dialog. Log on as Administrator from this point.

To log the Administrator off, click [Start] [Log Off] and [Log Off] when the [Log Off Windows] selection box appears. The Log On screen with the available users will be displayed.
To Make the Administrator Account Always Visible on the Login Screen use this Registry Tweak.

[Start] [Run] [Regedit]
Go to: HKEY_LOCALMACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList

Modify/Create DWORD Value of Data type REG_DWORD Named [Administrator]
Setting for Value Data: [0 = Disabled / 1 = Enabled]

Exit Registry and Reboot your system.

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 debugging programs, unassembling and cracking, and reading "hidden" memory areas like the boot sector, and much more. 

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

now type "?",after "-" 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 <address> <drive letter/> <sector> <amount to load>
-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]

Now, this tip will be very helpful for those who frequently install Windows XP operating system.

Normally OS installation takes around 40 minutes to complete, but through this trick you can now save 10-15 minutes.

This simple tricks goes this way.

1. Boot through Windows XP CD.

2. After all the files are completely loaded, you get the option to select the partition. Select “c”.

3. Now Format the partition, whether it is normal or quick with NTFS or FAT

4. Once the formatting is completed, All the setup files required for installation are copied. Restart your system by pressing Enter.

Now, here begins the Simple trick to save 10-15 minutes.

5. After rebooting, you get a screen where it takes 40 minutes to complete or finalize the OS installation.

6. Now, Press SHIFT + F10 Key ->  This opens command prompt.

7. Enter “Taskmgr” at the command prompt window. This will open Task Manager.

8. Click the Process Tab, here we find a process called Setup.exe -> Right Click on Setup.exe -> Set Priority -> Select High or Above Normal.Initially it will be Normal.

That’s it, no more work to do. Relax your self and see how fast the installation process completes

Just because Windows XP has the Add/Remove Programs feature it doesn’t mean your application will appear in the
list.

Furthermore, even if it does appear, it’s no guarantee that the uninstall feature will work.

When you run across one of these situations the items listed below will help in getting rid of the application. Be aware that these steps may not remove everything associated with the application and can impact other applications on the computer. Have a backup or restore point and use caution.

Find the directory for the application and delete all the files in the directory. Delete the directory.
Open regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE and find the folder for the application. Delete the folder.

Open regedit and navigate to HKEY_CURRENT_USER\SOFTWARE and find the folder for the application. Delete the folder.

To remove the application entry from Add/Remove Programs (if present) open regedit and navigate to
HKEY_LOCAL_MACHINE\SOFTWARE \Microsoft\Windows\CurrentVersion\Uninstall and find the folder for the application. Delete the folder.

Some applications have Services attached to them. If this is the case, navigate to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services, locate and delete the service.

In Windows Explorer, navigate to the individual user settings and delete program references. Common places to check would be:
C:\Documents and Settings\All Users\Start Menu\Programs and delete relevant entries.
C:\Documents and Settings\All Users\Start Menu\Programs\Startup and delete relevant entries.
C:\Documents and Settings\%YourUserID%\Start Menu\Programs and delete relevant entries.
[Do this for each User ID listed]
C:\Documents and Settings\%YourUserID%\Start Menu\Programs\Startup and delete relevant entries.
[Do this for each User ID listed]

If no entries were found in the previous step and the application launches automatically, navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
and delete the entry.

There is a trick in windows which gives you the opportunity to hide any type of files in a JPG file.

This simple trick can be achieved in few steps:

1. Select the files you want to hide and compress them using winrar,winzip etc…

2. Drag the compressed file and a random picture in the same directory(e.x. C:\)

3. Go to Start–>Run and type cmd in order to open the command prompt window
Go to directory where you have placed the files (type cd.. twice to go to C:\)

4. Type:
COPY /B "name".jpg + "name".zip "new name".jpg

After that process a new jpg file will be created in C:\ with the name: new name.

If you double click you will see just the image,but if you right click to the file and select extract,your hidden files will be extracted.
