I am very much a novice, but I am learning. I have a Windows 7 64 bit. Windows defender needs to be manully started. I found the following instructions.What does this statement mean, specifically " run each command in an elevated command prompt ? How do I do this ? Thank you. Claudis.

Re-register the following dll files and see if it helps you. Run each command in an elevated command prompt one after the other and hit Enter:


regsvr32 wuaueng.dll

regsvr32 wucltui.dll

regsvr32 softpub.dll

regsvr32 wintrust.dll

regsvr32 initpki.dll

regsvr32 wups.dll

regsvr32 wuweb.dll

regsvr32 atl.dll

In Windows 7, click the Start orb, type cmd then at the top of the list that comes up, right-click the "cmd.exe" and select "Run as administrator".

How to open an elevated Command Prompt <- shows several ways to do this

Where did you find those instructions? They are generally used to re-register Windows Update components...but I have seen them provided in this topic: Windows Defender is turned off or not working

What other security products do you have installed on this machine?
Did you check to make sure the Windows Defender service is running (enabled)?

These are instructions for restarting Windows Defender if it has been stopped...How to Start/Stop Windows Defender service

To start (enable) a service, press the WINKEY + R keys on the keyboard or click the Start Orb > Run...,
and in the Open dialog box, type: services.msc
Click OK or press Enter.

Note: You can also click the Start Orb and in the Search Box, type: services.msc

Windows Services will open:
  • Click the Extended tab at the bottom to view all the info on your services.
  • In the Services applet, scroll down the list and find the Windows Defender service.
  • Double-click on the name of the service to open the Properties page.
  • In the Properties Window > General Tab that opens, click the "Start" button if it is stopped.
  • From the drop-down menu next to "Startup Type", click on "Automatic".
  • Click "Apply", then "OK" and close any open windows.

regsvr32 is a Windows command line utility to register COM/ActiveX objects.


You need to be administrator and use your administrative rights to register COM/ActiveX objects. That is why you need to elevate your command-line prompt (cmd.exe), at least if you use Windows Vista or later.
