Where can I download the last WindowsDefender.msi to repair, modify or reinstall ?

Best Regards

P.D. I think my problem is a rest of an old virus

 

I find this link
Problems starting Windows Defender in Windows 8/8.1/10

In all my attempts to solve the problem I observ some entries in the registry with MSASCuiL.exe
Usually detected by Ccleaner.

Defender Icon changed to Shield

 

It's different from the one appear in wikipedia :
File:Windows Defender icon.png - Wikipedia

 

Because many users use a blue background, the blue icon was hard to see. I suspect they changed it to a white shield to make it easier to see. The one shown in Wikipedia is outdated.

As long as you see a white check mark in a green dot in Security Center like below, you are okay.

 

Mine has the White shield ever since I can remember.

 

This change was introduced in the Insider Preview a couple of months back. It shows in the "Creator" update.

 

i don't find now , but I remember see an old icon somewhere. so I preocupied about this. I will try to locate where.
Best Regards

 

The old icon remain in Activity Center - security...

 

If you read the Wiki - you would see it related to Vista!!
I would imagine that the icon used in all current MS info would be the latest icon. Does it matter what icon is used? A wall - to protect. A shield - to protect.
