• Windows update error - "Code 80070643 - Windows has encountered an unknown error"

  I am running windows Vista SP1 and for the past month, it does not install updates.

  My security software (ESET Smart Security 4) keeps telling me that my system is not up-to-date and when I check the windows update, I have accumulated lack updated for a month. Previously, they have updated very well, but I think the problem started when he tried to install windows vista service pack 2 and failed with an "unknown error".

  When I try to install the updates, Windows Update displays an error message saying that it has to update the version of the Windows Update software but when I click on continue, I get "Code 80070643 - Windows has encountered an unknown error. No updates are then installed.

  Office Source Engine setting to automatic, what I did, but that makes no difference, suggested the online help.

  Can anyone help?

  Thank you very much.

• Installed windows 7 and windows live mail. now I want to import my messages from windows mail, and they will not matter. I really need the messages because they have a lot of important information in them.

  Would be really happy for any help.  The application tells me that they have been moved to the storage area, but they are not there.

  Help.

  Is your username mentioned in the tab security for storage files and all subfolders, and has 'full control '?

  If these files are really empty then the transfer/import routine failed for some unknown (to me) reason.

  Have you tried to copy all old messages from the Windows.old folder, put in a file in your user name for example Documents and then import from there?   It is perhaps necessary to remove to another location in the current storage folder in Windows Live Mail rather than simply delete before rerunning the import program.

  Have you tried to temporarily disable your anti program virus and other security programs to see if that blocks emails appear?

  Try running ChkDsk to check your drive for errors. Right click on your drive icon / properties / tools / error checking.  First try checking not be (read-only) to see if it reports any problems file or hard drive.  If this is the case, start by checking the two boxes, in no other rerun.

• How can I add more capacity to my email? I tried to send attachments, and they are not sent, says that it's too big

  I need to be able to send attachments, for my work.  I need to increase the capacity for the things sent.  How can I do this?

  How great the message you can send is depends on your ISP. They put
  the limit, no Windows, and not your e-mail program.

  Ask them what the limit is, and whether you can change it. But be
  aware that it is likely that you can not have the raised limit.
