How to Enable Windows 8 Picture Password?

Recently Microsoft has launched Windows 8 Operating System with many new and unique features as compared with its earlier version Windows 7. Out of these new and unique features, picture password is one of the features which is very attractive and getting popular as lightening speed. This feature allows its user to prevent unauthorized access by enabling password with the help of picture. In picture password authentication system, user can select any picture (to appear on login screen) and register specific patterns by touching (or dragging) finger on the picture.

If you are Windows 8 user and wanted to enable picture password then you can following these steps as given below.

1. Click "Settings" on the Charms bar.

2. In settings panel click "More PC Settings" -> Click "Users" (on the left side of the screen).

3. On clicking "Users" you will see your account information. From "Sign-in options" click "create a picture password" button.

4. You will see "Picture Password Wizard". In the first screen of wizard you will be asked to select a picture to be used for password.

5. After selecting picture you will need to register (two times) 3 gestures on picture by dragging your finger on the picture. You can draw gestures in any shape like line, circle, triangle etc.

Note : Be careful about the direction in which you draw gestures because they are direction sensitive.

6. If you get success in making same gesture (depending upon some accuracy level) then Windows 8 saves it as picture login password for your account and from next time onwards you need to repeat this gesture to login to your user account in Windows 8.

So, now no need to remember long and complex passwords, login quickly by dragging finger on picture. I am sure you will be very excited to share this great feature with your friends too.

Password protection is one of the most important features of MS Excel. Password protection feature ensures that only authorized user can see or modify the data of the excel file. This feature allows user to set (mainly) two types of password on excel file: Password to open and Password to modify. First type of password (Password to open) restricts the user from opening the excel file whereas second type of password (Password to modify) can be used to protect excel sheet (or cells) from unauthorized modification.
Many times it happens that the authorized user forget excel file password and hence they also lost access from opening/editing the excel file. In such situation most of the user take help of excel password remover software to recover lost password.
Here I am sharing how you can edit read only password protected excel file without any password remover software.
  1. Login into your Gmail account.

  2. Click on documents (or open after you have login into Gmail account).
  3. Click Upload Document icon.

  4. Browse the file you want to edit and upload it.

Unprotect Excel Sheet with Brute-Force Attack and Masking Technique

MS Excel provide many features to manage and analyze large volume of data. Graphical representation tools and inbuilt (mathematical, financial, statistical and logical) functions make it very easy for everyone to analyze and summarize data without any special expertise. Besides so many user friendly features, MS Excel also provides a very useful security feature called “Password Protection” to prevent unauthorized access (or modification) of valuable data. This password protection feature of MS Excel allows User to protect entire workbook, individual sheet or cells of a file. 

Many times it happens that Excel user forget the password enabled by them to protect their worksheet. In such situation it is really very difficult to unprotect excel sheet without password remover software. I searched a lot to find methods of removing excel password without software but did not get even a single method which can do this. From my search I analysed that almost all the excel password remover software are based on two features: Brute-Force Attack Technique and Masking Technique.

Let me explain you how Brute-Force Attack and Masking Technique help to unprotect excel sheet. 

Brute-Force Attack Technique – This technique involves making all possible permutations of characters (lower case letters, upper case letters, special characters, numbers) of your password. All excel password breaker software provides you the option to specify the probable length and characters in your password. On the basis of the password length and characters all possible permutations are made and run through for checking. Total time taken by software to recover excel password directly depends on the total number of permutations (which in turn depends on the length and complexity of your password). 

For example if your password is 3 characters long and include numbers, Upper case and lower case letters then there will be total 62 * 62 * 62 = 238328 guesses or permutations (Here 62 = 26 lower case letters +26 upper case letters + 10 numbers).

Masking Technique – Many time it happens that user remember first few (or any) characters of their password but not able to recall full password. In such situation Masking Technique allows user to specify the initial (remember) characters and replace the unknown characters by '?'. This helps Brute-Force process to search for the unknown characters only and hence reduces the time to crack excel password. 

Overall we can say that because of Brute-Force Attack and Masking Technique excel password remover software has very high success rate. So, if you forget your excel file password then you can use any excel password recovery software based on Brute-Force Attack and Masking Technique.

How to Solve the Problem “Outlook keeps asking for password”?

Many Outlook users complain that Outlook keeps asking for password (network password) repeatedly. Situation becomes worse when “Enter Network Password” pop-up message appears after every 20-30 seconds. Pop-up keeps on flashing even the user has entered correct username and password. Enabling the “Save Password” or “Remember Password” also does not solve the problem.

The possible reason for this problem can be:
  • Corrupted Outlook profile.
  • Registry has incorrect Protected Storage System information.
Solving corrupted Outlook profile problem:

This problem can be solved by creating a new outlook profile and connecting this profile to the .pst file of old profile (or damaged profile).
  1. Create new outlook profile.
  2. Locate the .pst file used by damaged profile (you can find it at location C:\Documents and Settings\ user_name \Local Settings\Application Data\Microsoft\Outlook\Personal Folders.pst).
  3. Configure new profile to use .pst file of old profile. This can be done by following the given below steps (based on MS Outlook 2010):
    1. Open Outlook.
    2. File tab -> Info -> click Account Settings (in Outlook 2007 Account Settings option is available in Tool menu, in Outlook 2003 and 2002 Tool -> Options).
    3. E-mail tab-> click your email account. (in Outlook 2003 and 2002 Mail Setup -> Email Accounts -> View or change existing e-mail accounts - > Next)
    4. In the "Account Settings" dialog box Click "Change Folder".
    5. Click New Outlook Data File-> click Office Outlook Personal Folders File-> click OK.
    6. Browse and locate the .pst file of old profile-> click OK.
Solving Incorrect Registry information Problem:
  1. Close all the programs
  2. Click Start -> Run
  3. Enter "Regedit" and Click "Ok"
  4. Locate the folder : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
  5. Edit Menu-> New-> Expandable String Value
  6. Name it as "AppData"
  7. Double click new entry and write "%USERPROFILE%\Application Data" in "Value data field" box.
  8. Click "OK" and Close the registry editor.
Note: Before following this solution make sure that you have created a backup copy of registry.

I hope that with the help of these two methods you can make outlook to remember your mail password. So no more complaints that Outlook keeps asking for password.
