Nothing to do except getting back to Windows 7 or Linux in order to keep mining Ethereum until April 2019 when DAG will reach officially 3 GB in size.
Or Win 8.1 / 2012 R2
Btw, max epoch I could reach on Server 2008 - 231, 2012 R2 - 230.
Friend of mine tried *nix(EthOS I think) - 230 max.
Server 2019 - same as Win10. Killing DWM and explorer or Core(no GUI) install does not help.
So not April, but Jan prly.
