how do i fix error ox800106ba


Hi Anon,
The 0x800106ba error may occur after Windows Defender is updated due to the computer's inability to update the Windows Defender firewall. It may not have applicable permissions needed for the update, or it may not have the files necessary for updating itself.

The Fix

Set Windows Defender to Automatic - You can set the Windows Defender service to Automatic, Disabled or Manual. Setting it to automatic might solve the problem. Follow these steps:
  1. Click Start > type services in the Search box > click Services in the Programs list.
  2. If you are asked for a Password before you continue, then enter the password > click Continue.
  3. Double-click Windows Defender, and click Automatic in the start-up box > click OK.
Uninstall and reinstall Windows Defender - If the first procedure did not help resolve the problem, try un-installing and then reinstalling Windows Defender. Due to the fact that Windows Defender is a Windows component, we will use AppWiz to un-install it from the computer. Follow these steps:
  1. Press Windows Key + R > type appwiz.cpl > Press Enter
  2. Click Windows Defender > click Remove
  3. Follow the prompts to uninstall Windows Defender

Let me know how you go!

how to fix windows defender for free


The Windows Defender software constantly scans your computer for threats such as spyware that may slow down your computer or try to steal personal information. If the software wasn't installed properly or is conflicting with other programs running on your machine, Windows Defender may not work correctly. To repair the software you either need to download the latest update available for the program, or you need to completely uninstall and reinstall Windows Defender.

Restart your computer's operating system. Double-click the "Windows Defender" icon in the system tray at the lower-right end of the screen. Click the question mark icon at the top of the Windows Defender screen and choose "Check for Updates." Select "Continue" if you are running Windows Vista. Wait for the updates to finish installing and click "Scan." Click "Stop Scan" if the problem persists. Click the question mark icon again and select "Exit Windows Defender." Click "Yes" to confirm you want to close the software. Open the "Start" menu screen and select "Control Panel." Select "Uninstall a Program" in Windows 7 or Windows Vista, or instead choose "Add or Remove Programs" in Windows XP. Click the "Windows Defender" entry and select "Uninstall." Choose "Yes" and restart the computer after the program is removed. Navigate to the Windows Defender installation webpage (see Below). http://www.microsoft.com/downloads/details.aspx?FamilyId=435BFCE7-DA2B-4A6A-AFA4-F7F14E605A0D&displaylang=en&mg_id=10134 Click "Download" and double-click the Windows Defender installation file when it downloads to your hard drive. Go through the onscreen installation instructions. Open the "Start" menu and choose "All Programs." Select "Windows Defender." Click "Scan" to start a new scan for malicious software. Hope this helps
