• Windows Defender does not open

  I recently had to reinstall MS Security Essentials. Now cannot open/start Windows Defender. A window appears and says that WD is off. When click to open get message - "WD has encountered an error: 0 x 80070424 - the specified service does not exist as an installed service'." "

  have always been able to use it - obviously was and should be installed/available service!

  Any advice much appreciated

  It's normal. Windows Defender is disabled or in XP uninstalled when you install Microsoft Security Essentials because MSE includes the Windows Defender antispyware feature. If you use XP and Windows Defender is still listed in Add/Remove programs you must uninstall/remove it.

  Exactly what virus or other malware, have you been hit with? How do you have
  I know? They were removed? How?

  What anti-virus and anti-spyware programs you have installed? Are
  they kept up to date?

  Be aware that Microsoft Security Essentials and safety

  they contain a lot of the same functionality.

  My Windows Mail does not open.  It gives me a message saying, ' Windows Mail could not be started because MSOE. " DLL could not be loaded. "How can I fix in order to regain access to my e-mail address?

  The only other thing I can suggest is to back up and then delete the following registry keys:

  HKEY_CURRENT_USER\Identities

  HKEY_CURRENT_USER\Software\Microsoft\Windows Mail

  I start with the first and then see if it works.  If this isn't the case, then delete them both.
