Whenever you log in to a website using your username and password, you'll be prompted by Firefox whether you'd like Firefox to remember this password.

If you click on Remember, the next time you visit the website, it'll automatically enter the username and password for your convenience.

Now, back to the topic. Let's say you saved your Yahoo password in Firefox. After months or years gone by and you don't remember the password you set for my Yahoo. You started to panic and desperately need to get back your Yahoo password.
Don't worry, here's how you can find the hidden Yahoo password in Firefox.

Firefox is much better than Internet Explorer in terms of managing "remembered" logins. In Internet Explorer, there is no built-in feature where you can manage or view your saved login information. That's why you need third party tools to reveal the passwords hidden under asterisks. As for Firefox, you can access remembered passwords with a few clicks.

To view your remembered passwords in Firefox browser, go to Tools, and click on Options. Go to Security tab and click on the Show Passwords button. A remember password dialog box will appear. Click on the Show Passwords button again and a new column with password will appear.

Here is a trick to add your name in place of AM and PM beside time in the taskbar.

This trick 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

"con" or "nul" or "Aux" or "Lpt1".Windows will not let u create ....

Reason: all this correspond to some of the famous ports

First this trick need an ntfs disk, if u have fat or fat32, the convert it here is how: open ms-dos and write

convert X:/fs:ntfs
Replace X by the drive name (c or d or e)

For example... for drive C:\
convert c:/fs:ntfs
now select a drive (c or d or e.......) right-click and propreties, then click on general and select "compress drive to save disk space" and press ok...no data will be damaged or removed.

when double clicked on this drive an error message will open saying it is inaccessible .This is an alternate to hiding a drive and making it inaccisible. Here's how u do that :

Go to the registry editor and navigate to the following place :
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
In the right hand pane for the Explorer key, create a new "DWORD" value named ViewNoDrive

Double click the new value and enter it as .......
for hiding A drive set value as 1 , for B its 2 and C its 4 and so on and for Z its 33554432
generally multiply it by 2 for the next alphabet to hide.
Once done, reboot or log off and login in again. Then try double clicking the drive you made inaccessible.
You should receive a message stating that the drive cannot be accessed

& type Regedit

ContentIndex

now there find the Key Called
"Startup Delay"
Double Click On It
Now where its Base
Click Decimal
Now its Default Value Is 4800000(75300:hexadecimal)
Change The Value To 40000
here u go u have done it
now close the Registery Editor and Restart Your Computer
You'll See The Result

Once done, you will be able to right click any file or folder and use the Browse for Folder dialog to choose the location you want to move or copy your file or folder to, without having to go to the destination path, its cool!

First we will add the copy and move options to the right click menu of all FILES.

CLICK Start>Run, type REGEDIT and click OK to open up the registry editor and make your way to this key:

HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers

Right click the ContextMenuHandlers key and choose New>Key.
Name the new key “Copy To” (without the quotes).
Repeat the above and create another new key named Move To.

You should now have two new subkeys under the ContextMenuHandlers key:

HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\Copy To
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\Move To

Select the Copy To key and in the right hand pane, double click “Default”
Enter this clsid value as the value data:

{C2FBB630-2971-11d1-A18C-00C04FD75D13}

Next , select the Move To key and in the right hand pane set the default value to:

{C2FBB631-2971-11d1-A18C-00C04FD75D13}

This now takes care of the Copy and Move options for the right click context menu of all your files.
Now all that is left is to add the same options to the right click menu of all your folders.
The procedure will be the same as for files but at a different key:

HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHan dlers

Right click ContextMenuHandlers and create a new key named Copy To.
Right click it again and create another new key named Move To.

left click on the right hand pane, add the same default values as you did for Files:

For Copy To:
{C2FBB630-2971-11d1-A18C-00C04FD75D13}
For the Move To:
{C2FBB631-2971-11d1-A18C-00C04FD75D13}

Exit the registry and you are done.

Now when you right click on a file or folder, you should see two new options: Copy to Folder and Move to Folder

All you need is WinRAR INSTALLED ON Windows XP.

Gather all your files

Now add those files in a RAR Archive
For example Secret.rar

Now copy the RaR file to a folder.
For Example : C:/hidden/

Now copy any image which is in JPEG format to the same folder above.
For Example logo.jpg

Now Open MS-DOS
Start > Run type "cmd" without quotes.

In Dos window something like this should be written
"Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.
C:\Documents and Settings\Administrator>"

to change it to C:/Hidden/
type "cd\" without quotes.
then type "cd hidden" without quotes.

then type this
COPY /b logo.jpg + secret.rar output.jpg

Now you will see a output.jpg in that "C:\Hidden\" folder.
Now only winrar can open it

Now access the internet via your standard Microsoft Calculator using this trick.
You can do this for fun or when your browser is messed up for some unexplainable reason.

Steps:

1. Open your MS Calculator. This is normally found in Start => All Programs => Accessories => Calculator.

2. Open the help-window by pressing the F1 key.

3. Click the top-left corner icon of the help window once (Standard is a Document with a Questionmark).

4. Select 'Jump to URL'.

5. Type your address into the avaliable field, but remember to type http://, and not just www. (or equivalent).

Have fun !!!

Who wants to delete "RUN"

I really don't know why someone could wish to remove RUN from START MENU, but if you're one of them, you can do that, too.

REGEDIT

HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Policies\Explorer

Double click on "NoRun" and change "ValueData" from 0 to 1.

Close Regedit, and restart computer.
Done!!
