Re: Windows 10 Fail
"still won't let you read Linux files from Windows"
This is meant to run Linux under Windows on top of an NTFS or ReFS filesystem - Why would you then need another Linux install on the local system ? If it's not local you just use a network share... So an EXT4 driver is not really something I would expect Microsoft to provide. If it was a multi-access file system that made sense for the cloud then maybe, but it isn't.
If you really need to access Linux local EXT file systems then there are several third party driver solutions for Windows.
