I have upgraded from Windows 7 Home Premium to Windows 10. I never used Windows Defender previously, but I want to now. I have trouble starting Windows Defender, I am not using any third party antivirus. Whenever I start Windows Defender it shows a message "The service couldn't be started" and in detail it shows error code 0x8007139f. What could be the reason for this?

Have you completely removed your previous anti-virus?  Also, try running the uninstaller for the previous anti-virus to clean up any leftover remnants.  I have a list of them here:  http://www.carrona.org/avuninst.html

Double check to be sure that all Windows Updates were successfully installed.

Did you try other free scans to see if the system is infected?   Here's a list of a few free scans (from this link: https://www.us-cert.gov/ncas/alerts/TA15-286A ):

 

           F-Secure
           https://www.f-secure.com/en/web/home_global/online-scanner (link is external)

           McAfee
           http://www.mcafee.com/uk/downloads/free-tools/stinger.aspx (link is external)

           Microsoft

           Sophos

           Trend Micro

Looks like that page is broken (I get the same behavior).

Have you tried any of the other links?

 

I tried it in Firefox and got that behavior.
I tried it in Edge and it worked just fine.

I tried it in IE11 and had a couple of crashes before it settled down and worked.

Don't bother with WinDef, it's the lowest rated AV in the world, by a large margin, just check any AV test site, it's always at the bottom of the list.

 

Use a good one, free are Bitdefender, Avast, Avira. Paid, the top of the heap is Kaspersky.

 

That being said, if you are bound and determined to use WinDef, here's the fix:

There's a bulk of solutions for fixing this error. Try one by one until the issue fixed. For my case, I just reset the PC & done :)

1. Restart your PC

2. Remove existing antivirus and antispyware software

3. Scan your PC for malwares

4. SFC scan

5. Clean Boot

6. Restart Security Center Service

7. Delete conflicting Registry Entry

For step-by-tep, you can also refer to the source post here: How to fix Error 0x8007139f when scanning with Windows Defender?

This problem may occur after Windows Defender is updated, To resolve this problem, follow these steps:

 

  1. Set the Windows Defender service to Automatic instead of Disabled or Manual. To do this, follow these steps:
    1. Click Start, type services in the Start Search box, and then click Services in the Programs list. If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
    2. Double-click the Windows Defender service, and then in the Startup type box, click Automatic.
    3. Click OK.

 

Hope this helps. If you need further assistance with Windows, let us know and will be glad to help.

Do not use Windows Defender for anything. It is rated as the worst AV in the world by many test centers. Look it up.

 

Look up best AV's 2016, use any one of the top, namely:

 

     Avira 

 

     Avast

 

     Bitdefender

 

    AVG

 

Any of those will work fine.
