Hello kludge, :)
The tutorials below can help show you how to turn off Windows Defender Smartscreen. It is not recommended to turn this off though.

Windows Defender is useless without smartscreen, so disable it only if you are using another AV.
To get rid of the process, you can remove it or rename it. To restore it, run SFC scan.
Code:takeown /f "%WinDir%\System32\smartscreen.exe" /a icacls "%WinDir%\System32\smartscreen.exe" /grant:r Administrators:F /c taskkill /im smartscreen.exe /f del "%WinDir%\System32\smartscreen.exe" /s /f /q
Brink,
Of course! Warning, don't try this at home!
The website told me about the Tutorials when I posted and they solved the issue.
Thanks for the response!
TairikuOkami,
If Windows Defender was truly useless then it would not flag the Eicar Test File while SmartScreen is disabled. Finding the test file proves Windows Defender is working and not as useless as lead to believe.
Thanks for the script and taking the time to respond!
Thanks to @TairikuOkami for his solution but sometime since then smartscreen.exe reappeared.
I want to take his method one step further and remove access by the system to smartscreen.exe
so I offer my solution here.
Disable smartscreen.exe permanently, can't run, can't be overwritten by system (except reinstall),
can't be fixed with sfc:
Code:takeown /f "%systemroot%\System32\smartscreen.exe" /a icacls "%systemroot%\System32\smartscreen.exe" /reset taskkill /im smartscreen.exe /f icacls "%systemroot%\System32\smartscreen.exe" /inheritance:r /remove *S-1-5-32-544 *S-1-5-11 *S-1-5-32-545 *S-1-5-18
Reset smartscreen.exe to default permissions:
Code:takeown /f "%systemroot%\System32\smartscreen.exe" /a icacls "%systemroot%\System32\smartscreen.exe" /reset icacls "%systemroot%\System32\smartscreen.exe" /setowner *S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464
I wish this would have worked, came right back when I opened either Thunderbird or Wiindows Photos. Keeps showing up trying to phone home in my Windows Firewall Control popup. Any ideas? I've tried everything including the reg fix too. Shows its "off" in the registry, but still getting the popup from WFC that its trying to contact MS.
Try this, works on 2004 as well. But it is possible, that Windows Defender prevents malware like changes.
Code:reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer" /v "SmartScreenEnabled" /t REG_SZ /d "Off" /f reg add "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\PhishingFilter" /v "EnabledV9" /t REG_DWORD /d "0" /f reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\AppHost" /v "EnableWebContentEvaluation" /t "REG_DWORD" /d "0" /f reg add "HKLM\Software\Policies\Microsoft\Windows\System" /v "EnableSmartScreen" /t "REG_DWORD" /d "0" /f reg add "HKLM\Software\Policies\Microsoft\Windows Defender\SmartScreen" /v "ConfigureAppInstallControl" /t REG_SZ /d "Anywhere" /f reg add "HKLM\Software\Policies\Microsoft\Windows Defender\SmartScreen" /v "ConfigureAppInstallControlEnabled" /t "REG_DWORD" /d "0" /f takeown /s %computername% /u %username% /f "%WinDir%\System32\smartscreen.exe" icacls "%WinDir%\System32\smartscreen.exe" /grant:r %username%:F taskkill /im smartscreen.exe /f del "%WinDir%\System32\smartscreen.exe" /s /f /q
Thanks TairikuOkami
That may have done it. Says "SmartScreen.exe processes have been terminated". (cant help but think of the movie Terminator, every time I see the word "terminated")
I was trying to think of why I am seeing the smartscreen popup so much now on WFC, and then it hit me, that ever since I download photos and docs from my Android phone to the computer, this has started happening.
Something about doing that I think has triggered this, but smartscreen should have been able to be shut off without going through all of these command prompt hacks.
Anyway, lets see if this lasts.... if it comes back, I'm just going to "throw in the towel" and accept that MS is not going to allow changes to its SmartScreen.

@TairikuOkami Thanks for the script! Works Great! I know thats offtopic but do you have anything similar for compattelrunner.exe?(creates a lot of cpu usage sometimes and disabling tasks from scheduler doesnt solve it)
