I've got this error preventing Windows 10 updates. It's happening on 3 of my devices (All Windows 10). 
The 0x80070643 error, I'm led to understand is caused by AVG software controlling/overriding Windows Defender, but i'm not entirely sure. Either way, is there a simple fix for this error? I've followed various sets of instructions online on how to resolve it, but nothing has worked.
