1000s of folks ask here, but not one ever posted a photo of the screen that fails, and matters.
ever.
we can't see your screen ok,. hint hint.?

A username is the name that other people will see. It is not your real name, but rather an alias. Most places also require it when you login. Here is a wikihow page about how to make a username: How to Make Unique Username

Reset Your Windows Password Using the Command Prompt

1. Boot your computer using your Windows installation disc.
2. Wait for the setup files to load, and select your language. Click Next.
3. Click the Repair your computer link on the Install Windows screen.
4. Select the operating system to repair, and note the drive letter on which the OS is installed (it is probably C: or D:). Click Next.
5. Click Command Prompt at the bottom of the list of recovery tools.
Now you need to overwrite the Sticky Keys executable with the Command Prompt executable. Sticky Keys is an accessibility feature that allows a user to tap the Shift, Ctrl, Alt, or Windows key once to achieve the same effect as holding the key down. Ordinarily, tapping Shift five times activates Sticky Keys--but with this trick, you are going to make tapping Shift five times activate the Windows Command Prompt instead.
The instructions below use drive letter C: as an example. If your operating system is installed on another drive, replace C: with the appropriate drive letter.
1. In the Command Prompt window, type copy c:\windows\system32\sethc.exe c:\ and press Enter.
2. Type copy /y c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe and press Enter.
3. Exit the Command Prompt and reboot the computer. At the login screen, tap Shift five times. The Command Prompt will pop up.
4. Type net user username password, replacing username with your username and password with a new password.
5. Exit the Command Prompt, and log in using your new password.
To prevent another user from exploiting the same trick to reset your password, you can restore Sticky Keys as follows:
1. Step through the instructions above to boot the PC using your Windows installation disc, open the recovery tools, and launch the Command Prompt.
2. Type copy /y c:\sethc.exe c:\windows\system32\sethc.exe and press Enter.
3. Exit the Command Prompt and reboot the computer. Pressing Shift five times will now activate Sticky Keys instead of the Command Prompt. Store your Windows installation disc in a secure location.

Try adding a few numbers to it. Instead of choosing "username" as a username, try username, "username76", for example.

Here are the possible reasons why you would be unable to claim a username that seems available:

• Usernames containing the words Twitter or Admin cannot be claimed. No account names can contain Twitteror Admin unless they are official Twitter accounts.
• Your username cannot be longer than 15 characters. Your real name can be longer (20 characters), but usernames are kept shorter for the sake of ease.
• A username can only contain alphanumeric characters (letters A-Z, numbers 0-9) with the exception of underscores, as noted above. Check to make sure your desired username doesn't contain any symbols, dashes, or spaces.
• The username may be claimed by a suspended or deactivated account. Suspended and deactivated usernames are not immediately available for use, so you'll need to select a different username.

Hope that helps!

Run a time machine backup. Then the easiest way would be to find a photo that you are willing to delete in iPhoto.

Jot down the name of the photo file, delete it. Then empty the trash.

Then go into time machine, try to search for that file, when you locate it, restore it. If you can then there is probably a good chance that you time machine backup is good.

To be on the safe side why not create a manual backup.

You'll find the iPhoto Library at:

/Users/username/Pictures

"username" will be your name that appears when you login to the computer.

1. To get there, double-click the icon for your hard drive to open it, then double-click the Users folder. Double-click your Home folder, which is identified by a house icon and your username, and then double-click the Pictures folder to open it.
2. 1. 1. 1. Inside the Pictures folder you'll see a file called iPhoto Library. Copy the iPhoto Library file to a location other than your hard drive, such as your Maxtor external hard drive.

1. your account may not active .please contact bank for further information.

(note: the activation of the internet banking may take 3 weeks. be patient . ) user ID and user name are not different. you can also change your user name and password after login to your account.
important:please don't tell to others the username and password. SBI never ask to you to specify your username and password.
