[xubuntu-users] file system window read-only

[Alessandro Lin]

Hallo,

this work:

Access Window 10 Prompt with Super User (administrator) privileges. The 
access is somewhat nested but it is located.

Command:  powercfg / H off

exit and close the pc.

Restart the pc in Xubuntu.

The Window partition is read - write. Wonderful!

Edit 1 file and close the pc.

Restart the pc in Window 10. Everything is OK.

Edit 1 file and close the pc.

Restart the pc in Xubuntu. Everything is OK.

Regards.
