Windows the most widely used Operating System has many holes. With some operations you can easily customize (hack) your Windows
Operating System. Now let”s see some usable and funny tips and tricks..

Change the Windows start-up and shutdown screens:

Using this trick you can easily change the boring startup and shutdown screens. In Windows the screens are stored in the disk as
logo.sys, logow.sys, logos.sys. Find them on the disk and open them with “Mspaint”. Now you can do any thing with these files.
You can even add your pics as the startup screen. But remember that the width should be 320 pixels and height should be 400
pixels and save it the Windows directory as the logo.sys/logow.sys/logos.sys.

Get out of Windows without warning:

Using this trick you can shutdown or restart your Windows without any warning. For using this right-click on desktop and create a
short-cut and enter the command line as follows:
Shutting down: “rundll.exe user.exe,exitwindows” (without
quotes)
Restarting: “rundll.exe user.exe,exitwindowsexec” (without
quotes)
Note: you can even shutdown Windows by running this command in
Windows directory.

Catch your desktop:

To get the contents of your screen as an image file, press the “print screen” key on your desktop and open Microsoft Paint and
click paste in the edit menu (or press Ctrl+V). You can it as an image file.

video file.

Hack the Windows login passwords:

During Windows startup press F8 key (i.e., before the startup splash screen) and select “command prompt only”. Go to c:\windows
directory and delete the password file(*.pwl “ where * is the username) and restart the system. When the password dialog box
pops up, type the username and enter any password. Windows should accept any password.

Internet Explorer- Some tips to clean your tracks on your system:

If you are using Internet Explorer for surfing the net, it is the program which spies on your browsing habits and stores the files
you viewed in the hard disk. Any hacker by introducing a small Trojan program to your system can easily know your surfing habits.

Clear History:

The sites you visited over the internet with the Internet Explorer engine are stored in the history folder in your Windows directory.
You can delete the entries in the history folder by clicking the “Clear History” button in the Internet options dialog box. To
delete only a specific entry go the history folder in c:\windows and delete the entry.

 

Remove the temporary internet files:

Internet Explorer stores the images and pages viewed through it in the “Temporary Internet Files” folder in c:\windows directory.
Delete the files in it by clicking the “Delete Files” in the Internet Options dialog box in Internet Explorer. You can even
delete the files by browsing through the “Temporary Internet Files” folder in Windows directory.

Remove Cookies:

Cookies are the files used by the websites to know information about your last login to that site, your username in the site etc.
The information in these files is not user readable language. But, the cookie name tells the name of the site you visited. Delete the
cookies by browsing through the “Cookies” folder in Windows directory.
The above mentioned are some basic tricks you can play on Windows.
But, to really hack your Windows, there is no other better tool
than REGEDIT.

Working with registry:

Registry as its name indicates it is the central core registrar of windows system. It contains all information about the programs
installed on the system and how to respond to inputs of the user. Customizing windows is very easy by working with the registry. In
windows 95/98 the entire registry is stored in USER.DAT and SYSTEM.DAT; in windows Me there is another file called
CLASSES.DAT. In windows NT/2000 the registry is stored in %system root%\system32\config directory. But, you cannot edit these files
directly to change the values in registry. To change the registry settings there is an utility in windows known as “REGEDIT”. Using
this utility you can comfortably edit the registry to hack your windoze.

The registry has a tree structure and it looks similar to windows explorer. The entire registry is divided to six hives with further
have sub-keys and values. The six main hives in the windows registry are

HKEY_USERS “ This hive contains all information about the settings for each user on the system. If there is only one user then only
“.default” key will be present.

HKEY_CURRENT_USER “ This is the link to HKEY_USERS. It loads the appropriate settings like desktop settings, start menu settings
etc. for the current logged on user.
HKEY_LOCAL_MACHINE - This hive contains all information about the system starting from the hardware settings, software etc. to
information about the users on that system.
HKEY_CLASSES_ROOT “ This hive contains all information about windows shortcuts, file associations.
HKEY_CURRENT_CONFIG “ This is an alias to HKEY_LOCAL_MACHINE and
stores information about the current hardware configuration.
HKEY_DYN_DATA “ In this hive, changes in the values of registry
take place dynamically. So, this key is known a “Dynamic Data Key”.

The values to the sub-keys in the registry are defined by three types.
String: This type is used to represent human readable values
Binary: In this type the information is stored in hexadecimal
format. It mainly stores information regarding hardware
configuration.
Dword: This is a Boolean format. To disable a Key change its value
to “0” and “1” to enable the key.

When you right click on any key in the left pane of registry, the following options popup:
Expand: To expand the tree.
New: Creates a new key
Find: To find a sub-key in that key
Delete: Deletes the key
Rename: Renames the key
Copy Key Name: Copies the entire key

When you click on a key in the right pane the following options popup:
Modify: Modifies the value of the key
Delete: Deletes the selected key
Rename: Renames the key

Registry Editor is included with the windows operating system. To launch Registry Editor, click start and select run. In the Run dialog box, type “regedit” (without quotes) and click OK. You will now see the Registry Editor launched to the screen. In the windows
registry you can neither add nor delete the main hives. You can add or delete keys to these hives and even modify the values to the keys.

With this concept you can easily hack your windows system. But, be careful while working with registry. Editing the registry could
crash programs and even the entire Operating System. Now we shall see some tricks you can play on windows registry to
customize (hack) your Windows using registry.

CLSID folders- What they really are” In Windows Operating System, the system folders are protected from
accidental deletion. Each system folder is represented by a 16-bit value known as CLSID value in the Windows registry. These
values point to the specific system folders. These values are stored in the registry in “HKCR\CLSID”. Below given are some of
the CLSID values of some folders

Recycle Bin- {645FF040-5081-101B-9F08-00AA002F9554E}
Network Neighbourhood- {208D2C60-3AEA-1069-A2D7-O8002B30309D}
My Computer- {20D04FE0-3AEA-1069-A2D8-08002B30309D}
Control Panel- {21EC2020-3AEA-1069-A2DD-08002B30309D}
My Briefcase- {85BBD920-42AO-1069-A2E4-08002B30309D}

To delete a folder simply delete the corresponding value to the folder in the above key mentioned.
Note: To delete a key from the desktop go to
“HKLM|Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\Names
pace” and delete the corresponding key.

Customize the right-click menu of the CLSID folders:
The above explained process is not an efficient one to delete the system folders. There is another method by which you can
customize the right-click menu of the folder after which you can delete the folder or even rename the folder. Let”s look at this process.

This operation deals with editing the DWORD value of “attributes”
in the shellfolder of the corresponding CLSID folder. To do this go to
“HKCR\CLSID\{CLSID VALUE}\Shellfolder” and find the DWORD value
named “Attributes” in it and change its value to the following values according to your requirement.

70 01 00 20 “Adds both rename and delete to the menu
50 01 00 20 “ Adds only rename option to the menu
60 01 00 20 “ Adds only delete to the menu
47 01 00 20 “ Adds cut, copy, paste to the menu
40 01 00 20 “ Changes the menu to its default condition

Now you can do anything to the folders. But, remember editing these values could eve crash your system. So, be careful while editing them.

Playing with Explorer.exe:
Explorer is like the heart to Windows Operating System. It is mainly responsible for the originating windows in Windows OS.
So, the life of Windows lies in Explorer.exe. Now we shall see editing this file. Remember, editing explorer.exe is a complicate
issue to take a backup of all the important data you have and also have a copy of explorer.exe.

You can use DOS for hex-editing your explorer.exe or even any .exe file.

Change the “Start” text on Start button:
To do this restart your computer in MS-Dos and go to C:\Windows> and type the following command.
“edit /70 explorer.exe” (without quotes). The /70 option helps you to see only 70 columns on the screen. It is in the line 2390 of
the editor window, there is a text “S t a r t”. Now you can replace the text on start button with any word of 5 characters.
Simply replace the letters in “S t a r t” with any the required letters with null characters (remember not spaces) in between
them. Example: Replace the “S t a r t” with “S n e h a”.

If by mistake you typed a space between the letters, copy a null character from the remaining document and paste it over the
typed space.

Change the text over Clear button in Taskbar properties:
Follow the same procedure to open the Dos editor and to the line 1354 in the editor. You can find the word “& C l e a r”. Now
just replace the word with any other word with exactly 5 characters. The “&” signifies the shortcut key for the operation i.e., the
command gets executed when you press “Alt + C”. Example: I changed the “& C l e a r” to “& S n e h a”.

Restart your computer for the settings to take place. Like wise there are many operations that you can do to change the taskbar
properties and start menu items. All these can be found in between the lines 1336 to 2348. But be careful while editing it.

Note: The lines mentioned here are with reference to explorer.exe in a Win98 system. These lines may vary with explorer.exe in other OSs.

Disclaimer: Editing the registry and explorer.exe is a complicate
issue. Operations above mentioned could even crash your system.
So, always maintain a back-up copy while editing the registry or
explorer.exe. Perform the operations at your own risk. I am not
responsible for any kind of damage.
