Re - turn on Defender windows manually

I accidently turned off my windows defender and I tried to turn it back on via the features info help, but now it says that I have to turn it on manually and I can't find out how to do this.  Can someone please?

Hello chattykathy,.

However, if as Ken said, you have Microsoft Security Essentials, it will turn off Windows Defender.
Other antivirus programs can do that too. Windows Defender is part of the Windows Vista operating system and cannot be uninstalled, it cannot be disabled.

  1. Open Windows Defender by clicking on the button start, clicking all programs, and then click Windows Defender.

  2. Click on tools and then click Options.

  3. Under the administrator options, select or clear the check box use Windows Defender and then click Save. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

I hope this helps.

Sincerely,

Marilyn

    Norton is a 4 AVs programs (antivirus) which will stop Windows Defender.
    The reason is that Norton has its own advocate. Run 2 defenders in the same machine allows to create conflicts.
    So what you notice is normal.

    As for access to startup programs, defender of the window isn't the only way.

    Start > in the search box, type msconfig > Enter > Startup tab > here is the list of startup programs.

    To disable = uncheck the box in front.

    I would like to work in a quiet environment.  So I would like to turn off all Windows sounds without going through each of them via Control Panel-> Sound and defining each and every one of them (no).  I don't want to rely on turn off the speakers I could forget often because I do not use the speakers every now and then to use practice.

    If you want to silence your system completely, you can simply click on the volume icon and then select Mute.

    Now, if you want only to silence the sounds of Windows, open the Control Panel (large or small icons) and select audio, select the sounds tab. Under his regime to No. soundschange, at the bottom click on apply then OK.
