• I cannot perform certain functions because he says that I'm not an administrator, but it's my computer and I'm the only one who uses this computer__

  I cannot perform certain functions because he says that I'm not an administrator, but it's my computer and I'm the only person who uses this computer

  What are the functions? More global changes (changes to the system, software installation) require an elevation in Vista/Windows 7.

  Changes to the built-in Vista administrator account

  http://support.Microsoft.com/default.aspx?kbid=942956

  User - recommended configuration (Vista and Win7) accounts

  You absolutely don't want to have only one user account. As XP and all other Windows 7, Vista, and modern operating systems are operating systems multi-user with integrated system of accounts as default Administrator and comments. These accounts should be left alone because they are part of the structure of the operating system.

  In particular, you do not want account only one user with administrator privileges on Vista and Windows 7 because the administrator account integrated (normally only used in emergencies) is disabled by default. If you use as an administrator for your daily work, and this account is corrupt, things will be difficult. It is not impossible to activate the built-in administrator to rescue things, but it may require more work you want to do. Better not to get into a bad situation at first.

  The user account that is for your daily work must be a Standard user, with the extra administrative user (call it something like 'CompAdmin' or 'Tech' or similar) only it for elevation purposes. As a user Standard is recommended for security reasons and will help protect your computer against infections. After you have created "CompAdmin", connect to it and change your normal user account Standard. Then log on to your regular account.

  If you want to go directly to the desktop and ignore the Welcome screen with the icons of the user accounts, you can do this:

  Start Orb > Search box > type: netplwiz [Enter]
  Click continue (or provide an administrator password) when you are prompted by UAC

  Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null). MS - MVP - Elephant Boy computers - don't panic!

• Cannot perform the iTunes update

  Hello
  Try to update iTunes, I received the message (attached, in German):

  "There is a problem with the Windows Installer Package. As a result, cannot perform the update of iTunes. Contact the technical support. »

  What can I do?

  Thanks in advance for the help.

  Best regards, Alpe1

  Try to repair the Apple Software Update of the programs and features Control Panel, and then reinstall iTunes.

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  More information area has direct links with the current and recent buildings if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit-for old video cards) as a workaround for problems with installation or operation, or compatibility with QuickTime software or a third party.

  Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

  If the problem persists and you have a 64-bit system try for the old version of video cards which is a 64-bit Installer for most of the 32-bit code, similar to all 64 bit iTunes up to 12,1 versions.

  I get a message "Cannot perform this operation because the default mail client is not properly installed".  What should I do?

  Unlike Windows XP & Vista, Win7 does not have a default email Client. [What were thinking?]

  You will need to install a (e.g. MS Outlook;) Windows Live Mail; Thunderbird) , and then set it as a default for mail in CUSTOM (<>) article in Set Program Access and defaults of the computer , then restart your computer before any function send to or MailTo will become available.
