Simple Trick to Turn off all system beeps

If you want to turn off all system beeps (like the ones that go through your computers' internal speaker):

Start Regedit

Go to HKEY_CURRENT_USER\Control Panel\Sound

Edit the key Beep and give it a value of No

Disable Turn Off option in windows xp

Disable Turn Off Option ..and ALT+F4 option

REGEDIT->HKEY_CURRENT_USER->SOFTWARE->MICROSOFT->
WINDOWS->POLICIES->EXPLORER
THEN GO TO RIGHT SIDE AND BY RIGHT CLICK OF UR MOUSE CREATE NEW DWORD VALUE WITH NAME NoClose and after creating click on it and give Value Data 1.

And Reboot your pc ..now your Turn Off option is disabled ..to Enable it again ..go to that directory by regedit ..and simply delete that created NoClose and Log Off Your User and Log in again ..your Turn off Again Working.

Boot Or Start Computer Faster

Many computers take a lot of time to boot (or start ).This is due to many reasons.

Some slight changes can do wonders for your system:

1. Press start->run then type msconfig and press enter.

Go to the startup tab. Here you will see a list of startup items. These are all the programs that automatically start when you boot your PC. It is these that slow down the boot up process.
                                 So uncheck all the unwanted items like ms-office, messengers other utilities that u may not need at startup). Don't uncheck your antivirus software.

Restart your Pc to and see for yourself, your pc will now boot faster....

MAKE YOUR MENUS LOAD FASTER

This is one of my favorite tweaks as it makes a huge difference to how fast your machine will 'feel'. What this tweak does is remove the slight delay between clicking on a menu and XP displaying the menu.
 
Go to Start then Run
Type 'Regedit' then click 'Ok'
Find "HKEY_CURRENT_USER\Control Panel\Desktop\"
Select "MenuShowDelay"
Right click and select "Modify'
Reduce the number to around "100"
This is the delay time before a menu is opened. You can set it to "0" but it can make windows really hard to use as menus will open if you just look at them - well move your mouse over them anyway. I tend to go for anywhere between 50-150 depending on my mood.

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."

Hide Drives for security & Privacy

This is a great trick you can play on your friends. To disable the display of local or networked drives when you click My Computer.

1.Go to start->run.Type regedit.Now 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 (it is case sensitive).
Now modify it's value and set it to 3FFFFFF (Hexadecimal) .
Now restart your computer.
So, now when you click on My Computer, no drives will be shown(all gone...).

To enable display of drives in My Computer, simply delete this DWORD item that you created.Again restart your computer.You can now see all the drives again.

Remove Thumb.db file

Thumb.db is a cache of the current picture in any directory that contains Picture files for example: .jpeg. To remove it ,navigate to:
1> open "WINDOWS EXPLORER".
2>go to "TOOLS".
3>open "FOLDER OPTIONS".
4>go to "VIEW".
5>see 1st section "FILES & FOLDERS".
6>click on the "DO NOT CACHE THUMBNAILS".
Now the thumbnail file will be removed from your computer once u do this the file will be never created.

Make A Autorun File For Ur Cd

Did You Notice, whenever You Insert any game 0r software cd, or simply consider Windows Xp Operating system cd. As soon as You Insert the disk in CD-ROM, It automatically runs the cd. If you want to make a autorun file for that CD you are ready to burn just read this...

1) You open
notepad
2) now you writ: [autorun]
OPEN=INSTALL\Setup_filename.EXE
ICON=INSTALL\Setup_filename.EXE
Now save it but not as a .txt file but as a .inf file.

But remember! The "Setup_filename.EXE" MUST be replaced with the name of the setup file. And you also need to rember that it is not all of the setup files there are called '.exe but some are called '.msi

3) Now burn your CD with the autorun .inf file included.

4) Now set the CD in you
CD drive and wait for the autorun to begin or if nothing happens just double-click on the CD drive in "This Computer"

Disable simple File Shares

In Windows XP Professional, the Simple File Sharing mode is easily exploited, since it a little too easy to share out a file across your LAN (or the NET at large). To turn it off, go m My Computer, click Tools, Folder Option and the View tab, and uncheck Use Simple file sharing (Recommended). Click OK. When you do this you can access the Security tab in the Properties window for all folders; set permissions for folders; and take ownership of objects (but not in XP Home)

Disallow changes to IE settings through IE

This is another anti hijacker tip. IE can be set so that any changes to its settings must be performed through the Internet icon in the Control Panel, rather than through IE's own interface. Some particularly unscrupulous programs or sites try to tamper with setting by accessing the Tools, Options menu in IE. You can disable this and still make changes to IE's settings through the Control Panel.

Open the Registry and browse to HKEY_CURRENT_USER SoftwarePoliciesMicrosoftInternet ExplorerRestrictions. Create or edit a new DWORD value named NoBrowserUptions and set it to 1 (this is a per-user setting). Some third-party programs such as Spybot Search And Destroy allow you to toggle this setting.

You can also keep IE from having other programs rename its default startup page, another particularly annoying form of hijacking. Browse to HKEY.CURRENT USERSoftwarePolicies MicrosoftInternet ExploreControl Panel and add or edit a DWORD, Homepage and set it to 1.

Set the Hosts file to read-only to prevent name hijacking.

This one's from (and to a degree, for) the experts. The HOSTS file is a text file that all flavors of Windows use to hold certain network addresses that never change. When a network name and address is placed in HOSTS, the computer uses the address listed there for that network name rather than performing a lookup (which can take time). Experts edit this file to place their most commonly-visited sites into it, speeding things up considerably.

Unfortunately hijackers and hackers also love to put their own information into it - redirecting people from their favorite sites to places they don't want to go. One of the most common entries in HOSTS is local host which is set 1770.0.1. This refers to the local machine and if this entry is damaged the computer can behave very unpredictably.

To prevent HOSTS from being hijacked, set it to read-only. Go to the folder %Systemroot%system32driversetc, right-click on HOSTS, select Properties check the Read-Only box and click OK. If you want to add your own entries to HOSTS, you can unprotect it before doing so, but always remember to set it to read-only after you're done.

Fake out hackers with a dummy Administrator account

Since the default account in Windows 2000 is always named Administrator, an enterprising hacker can try to break into your system by attempting to guess the password on that account. It you never bothered to put a password on that account, say your prayers.

Rather than be a sucker to a hacker, put a password on the Administrator account it you haven't done so already. Then change the name of the Administrator account. You'll still be able to use the account under its new name, since Windows identifies user accounts by a back-end ID number rather than the name. Finally, create a new account named Administrator and disable it. This should frustrate any would -be break-ins.

You can add new accounts and change the names of existing accounts in Windows 2000 through the Local Users and Groups snap in. Right-click on My Computer, select Manager, open the Local Users and Groups subtree, look in the Users folder and right-click on any name to rename it. To add a new user, right-click on the containing folder and select New User. Finally, to disable an account, double-click it, check the Account is disabled box and click OK.

Don't ever delete the original Administrator account. Some programs refuse to install without it and you might have to log in under that account at some point to setup such
software. The original Administrator account is configured with a security ID that must continue to be present in the system.

Disable the POSIX and OS/2 Subsystem.

Windows 2000 and XP come with little-documented subsystems it at allow compatibility with UNIX and OS/2 systems These rues systems are enabled by default but so rarely used that they are best off bring disabled completely to prevent possible service hijackings.

To disable these subsystems, open the registry and navigate to HKEY LOCAL MACHINESYSTEMCurrentControlSetControlSession ManagerSubSystems. Delete the subkeys Os2 and Posix. then reboot.

Clearing the Page File at Shutdown

Windows 2000/XP paging file (Sometimes called the Swap File) can contain sensitive information such as plaintext passwords. Someone capable of accessing your system could scan that file and find its information. You can force windows to clear out this file.

In the registry navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory Management and add or edit the DWORD ClearPageFileAtShutdown. Set it to 1.

Note that when you do this, the system will take much longer to shut down: a system with a really big Page File (! Gig or more) may take a minute or two longer.

Remove "Orkut Is Banned" i.e.; Muhahaha! Virus

Easy Method to delete the virus.

Open task manager>process tab>there if you find svchost.exe befor your user name (Remember also system will use svchost.exe don't end that) just give end process for that then go to Run and type C://heap41a and Delete all files of that folder.. Now you are Done Enjoy Orkut..

Google search tips

define: - This google operator will find definitions for a certain term or  word over the Internet. Very useful when you come across a strange word when writing a post. I use this as a google dictionary. example :
info: - The google info operator will list the sets of information that    Google has from a specific website
site: - This google operator can be used to see the number of indexed     pages on your site                Alternative it can also be used to search for information inside a specific        site or class of sites.
link: - This google link operator allows you to find backlinks pointing         to your site. Unfortunately the count is not updated frequently and             not all backlinks are shown
allinurl: - Using this Google operator will limit the search to results         that contain the desired keywords on the URL structure. (i.e. allinurl:dailyblogtips)
fileformat: - Useful Google operator for finding specific file formats. Sometimes you know that the information you are looking for is likely to be contained in a PDF document or on a PowerPoint presentation, for instance. (i.e. “fileformat:.pdf market research” will search for PDF documents that contain the terms “market” and “research”)

Add network support

By default Windows Live MovieMaker won't let you import files over a network, but a quick Registry tweak will change this. Run REGEDIT, browse to HKEY_CURRENT_USER\Software\Microsoft\Windows Live\Movie Maker, add a DWORD value called AllowNetworkFiles and set it to 1 to add network support.

Calibrate your screen

The colours you see on your screen will vary depending on your monitor, graphics cards settings, lighting and more, yet most people use the same default Windows colour profile. And that means a digital photo you think looks perfect might appear very poor to everybody else. Fortunately Windows 7 now provides a Display Colour Calibration Wizard that helps you properly set up your brightness, contrast and colour settings, and a ClearType tuner to ensure text is crisp and sharp. Click Start, type DCCW and press Enter to give it a try.

Set the time zone in windows 7

System administrators will appreciate the new command line tzutil.exe utility, which lets you set a PC's time zone from scripts. If you wanted to set a PC to Greenwich Mean Time, for instance, you'd use the command
tzutil /s "gmt standard time"
The command "tzutil /g" displays the current time zone, "tzutil /l" lists all possible time zones, and "tzutil /?" displays details on how the command works.

burn ISO images

Windows 7 finally introduces a feature that other operating systems have had for years - the ability to burn ISO images to CDs or DVDs. And it couldn't be much easier to use. Just double-click the ISO image, choose the drive with the blank disc, click Burn and watch as your disc is created.

REMOVE ANNOYING DELETE CONFIRMATION MESSAGES

Although not strictly a

performance tweak I love this fix as it makes my machine 'feel' faster. I
hate the annoying 'are you sure?' messages that XP displays, especially if

I have to use a laptop touchpad to close them. To remove these messages:


1. Right-click on the 'Recycle Bin' on the desktop and then click

'Properties'
2. Clear the 'Display Delete Confirmation Dialog'

check box and click 'Ok'
If you do accidently delete a file don't

worry as all is not lost. Just go to your Recycle Bin and 'Restore' the file

SPEEDUP FOLDER BROWSING

you open my computer to browse folders that there is a slight delay. This

is because Windows XP automatically searches for network files and

printers everytime you open Windows Explorer. To fix this and to increase

browsing significantly:

1. Open My Computer
2. Click on Tools menu
3. Click on Folder Options
4. Click on the View tab.
5. Uncheck the Automatically search for network folders and printers check box
6. Click Apply & ok

(C:\programfiles\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 &amp; 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.
