Windows 10: Windows Defender blocking network access

I have been dealing with a strange issue for a few months since one of Windows 10 patches. About 80% of the time my PC boots, it cannot connect to my network or the internet. In the Windows Defender window, it indicates "unidentified network", then I disable Windows Defender, click on network troubleshooting to reset my adapter, then it will switch to "network 4", and everything works as it should. Going through this exercise every day is getting old. I have the TinyWall firewall that is more restrictive and Windows Defender, so I am tempted to permanently disable Windows Defender, but I would rather not. Any ideas?

Windows Defender is blocking too much saying it viruses

Hi Sam,

Based on the screenshot that you've provided, Controlled Folder Access is turned on, blocking most apps that you're using. We suggest that you turn it off to allow blocked apps in Windows Defender. Follow the steps below:

• Select Start > Settings.
• Choose Update & security > Windows Defender.
• Select Open Windows Defender Security Center.
• Select Virus & threat protection, and then choose Virus & threat protection settings.
• Under Controlled folder access, turn it on or off.
• Once done, try accessing the apps and see if you can now access them.

Should you need further assistance, feel free to post back.

The DWORD is set to 0 and I cannot get the process you suggested in the "NOTE" portion of the tutorial to work. Two attached screen shoots will show the before and after attempts to change the Permissions necessary for access to the DWORD change.




Access is denied. (Note-Protected folder in Defender is turned off)
