The registry is one of the most vital components of the Microsoft Windows operating system. In simple phrase, it is a complex database containing virtually all system, software, hardware and user settings. Almost every piece of software keeps its data in the registry. It is so important, that Windows would not even start without it.
The major part of all dangerous parasites, especially browser hijackers, trojans, spyware and adware threats modify the Windows registry. Parasites add various registry entries, create new keys, change default values. This is made in attempt to register a pest in the system, alter essential settings of the Windows operating system and installed software. Most of such changes are made for malicious purpose.
On our site you can find parasite registry entries that need to be manually removed. However, editing the registry is a difficult task that only advanced users and professionals can accomplish safely. Most anti-spyware programs will remove malicious registry entries for you. However, even the most powerful spyware removers might be unable to get rid of certain threats. The reason is simple: security software vendors cannot examine each recent pest immediately after it goes wild, and new pests appear almost every day. Anti-spyware tools rely on spyware definition databases. A few advanced products can find unknown suspicious files, but unknown harmful registry entries often stay unrecognized. This is why you need to know how to manually edit the Windows registry. But you have to be extremely careful. One inappropriate value, mistyped registry key or other small mistake in the registry may damage installed software and even corrupt the entire system! Do not modify the registry if there is no real need for this!
The following picture is showing how to open our registry you can also remove malicious registry entries from your computer registry.
Open run windows and type in regedit
This program consists of two panes. Use the left pane (on Image 2 it is designated by the red box) to navigate to certain registry key. In the right pane (it is in the blue box) you will see values, which belong to that selected key.
becaus of some computer viruses and spywares in registery some values change the scipt of show all option of folder option will not work you can follow this steps to make your folder options work again 
Sometimes a virus or some malicious script makes the hidden files and folders not visible even when it is explicitly enabled.
In this case even if the user enables the Show hidden files and folders in
Tools > Folder options > View menu, Hidden files and folder does not become visible.
Lets see how to fix it.Fix:First and foremost is the point that the user has enabled the Show hidden files and folder
1. Go to Tools > Folder options. This will show a folder options menu.
2. Go to View tab and select the option “Show hidden files and folder”
The hidden files and folders are displayed by this method normally. But in case some virus or script is preventing the hidden files and folders from being visible, follow the below steps:
1. Go to your Start > Run, type regedit and press enter. This will open registry editor.
2. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
Note:
DELETE the value CheckedValue in the right window if it already there and type is REG_SZ
Now create a new DWORD value again with the same name CheckedValue.
3. Double click the value called CheckedValue, and modify its data value (DWORD Value) to 1 (0×00000001) . Close registry editor after this.
If still folder options is reverted back to don’t show hidden files and folders then it could be due to some virus still in action.
Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden
NOHIDDEN
In the NOHIDDEN folder, select CheckedValue and set the value to 1
4. Go to Tools > Folder options. This will show a folder options menu.
5. Go to View tab and select the option “Show hidden files and folder
you can edit your windows register entries to do different things with your windows.
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
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

7) how 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
More
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.
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
