ISSUE IS BACK
Re-cap:
1809 pagefile issue - windows not recognising a pagefile on a non-O/S drive.
After a subsequent Microsoft update, the issue was resolved. Was able to use a pagefile on a non-O/S drive again.
Recent:
Later I found apps using odbc connections from my workstation to SQL Server on a server, crashed randomly.
To resolve this new issue, I uninstalled KB4493509.
This resolved the odbc connection issue.
But, now the original pagefile issue of windows not using my defined pagefile on my F: drive is back and windows created a temporary pagefile on C: drive.
