Some Windows 10 users are facing\u00a0 a curious issue: Windows reports after each login an offline Windows Defender and shows error code 0x80070578. Here a few hints how to solve this problem.<\/p>\n

<\/p>\n

\"\"In part 1 of this article series I cover the case, where a user is still able to login to his user account.<\/p>\n

The error description<\/h3>\n

I stumbled upon this issue within a Microsoft Answers post. A user reported a curious behavior.<\/p>\n

Windows defender offline (win 10) shows error: 0x80070578.<\/p>\n

After each restart Windows Defender offline drops the same error code. Windows can't be launched! There is an endless loop.<\/p>\n

How can I prevent my system from launching Windows Defender during Windows start?<\/p><\/blockquote>\n

Ok, the first question is, what is causing error 0x80070578? Error 0x80070578 stands for ERROR_INVALID_WINDOW_HANDLE. That isn't too helpful \u2013 and also this Microsoft Answers post<\/a> dealing with this error code doesn't help to much. But searching the web reveals a few more details.<\/p>\n

Missing Defender-Updates and third party AV software<\/h3>\n

The root cause for this issue seems to be caused from third party antivirus software. This software tries to deactivate Windows Defender, so Windows Defender won't be updated.<\/p>\n

Microsoft has announced a change in Windows 10: Limited Periodic Scanning in Windows 10 \u2026<\/a> allows two antivirus scanners running in parallel.<\/p><\/blockquote>\n

Fix #1 for the problem<\/h3>\n

The first solution is: Just uninstall your third party antivirus solution and run also a clean tool provided by AV vendor, to clean the system from install files\/entries left after uninstalling. Then reboot Windows and check, whether Windows Defender is active again. Then let Windows search for Defender updates and let Windows install those updates.<\/p>\n

Fix #2 for the problem<\/h3>\n

Another approach: Let Windows Defender update its signature files. Go to Settings <\/em>app and then let Windows search for updates. Maybe, Defender-Updates will be found and installed.<\/p>\n

If that doesn't work: Open an administrative command prompt (see Windows 10: Open command prompt window as administrator<\/a>) and enter the commands below:<\/p>\n

\u201e%PROGRAMFILES%\\Windows Defender\\MPCMDRUN.exe\" -RemoveDefinitions \u2013All<\/em><\/p>\n

This command removes the Defender signature files. The screenshot below shows this in my German Windows.<\/p>\n

\"Defender<\/p>\n

Then use the command below to fetch the newest Defender signature updates:<\/p>\n

\u201e%PROGRAMFILES%\\Windows Defender\\MPCMDRUN.exe\" \u2013SignatureUpdate<\/em><\/p>\n

After the Defender updates has been downloaded and installed, try a Windows restart. If that doesn't help, repeat Fix #1.<\/p>\n

In part 2 I will cover the case, where Windows 10 is locked in a Windows Defender Offline (WDO) boot loop, so the operating system can't start.<\/p>\n
