Same applies with build 17672 and 17677
AMD x64 system
Many non-Microsoft apps and app setups are erroring out with 0xc0000005 errors.
This recurring after second full clean reinstall, and redownloading the build. SFC run, no violations.
I've set the registry DisableAvCheck Dword to 1 and rebooted.
Avast Free Antivirus won't run or reinstall. My VPN client won't run or reinstall, utorrent and bit torrent won't run or reinstall.
I've also set HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_Dlls Dword as 1.
Still get 0xc0000005 errors. Hasn't happened before on any Win 10 builds, so something needs sorting urgently somewhere.
