  Windows Defender is disabled whenever I turn on my computer. setting has been activated automatically, but a message "windows defender is disabled" keep appearing one whenever I click on it. Help, please. Thank you!

  If you have Microsoft Security Essentials or AVG installed, you don't have to do a thing. These 2 are supposed to disable Windows Defender, because they have their own "defender". Running two defenders would conflict on the other and redundant.

  If you have not installed 2 above. Try this...
  Start bittun > in the search box, type services > press ENTER > uac prompt > scroll down and look for Windows Defender...
  under the State ; It must be said Started
  under Startup type : must say automatic
  If this isn't the case, right click on Windows Defender > properties >
  under the change of automatic startup type to
  under service status to start editing
  Click OK.

  Hello

  If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.

  There is nothing to worry.

  Using both programs at the same time can cause system conflicts, etc.

  If you are using one of the above AntiVirus programs, this Information from David O - Support Engineer shows you how to manually enable Windows Defender (disregard information from uninstalling; not possible in Vista):

  "Go to start, Control Panel, Administrative Tools, Services. Look for Windows Defender.

  Right click and select Properties , ensure that Startup Type is automatic.

  Once modified, click apply and OK.

  Quit and restart your computer. Check the back take the same path to confirm that Windows Defender has started"

  Hello osamanaiem56,

  Thanks for posting on the Microsoft answers Forum.

  I recommend that you look at the solutions of the following missions:
  http://social.technet.Microsoft.com/forums/en-us/itprovistaapps/thread/f5536f2d-ACEB-41A5-beb6-92e5d3b2f73f

  If this does not help then try the following suggestion:
  Right click on command prompt and run as administrator. Type the following command:
  WinMgmt /verifyrepository
  If the system returns "referential WMI is not consistent", run this command:
  WinMgmt /salvagerepository
  The first time you run this operation fails. (It will assign orders to stop services leading to failure. "This may take a few minutes for the services to stop). Run the command again. You may in fact need to run 3 times before finally runs and ends on its own.
  Reboot your system.
