It's likely this affects libguestfs since it runs wrestool on
Windows guests.  I'm not able to see bug 1544931 however so
I don't know if there is already a bug to fix this in RHEL 7.

Hi Richard! bug 1544931 is the task created for this issue and a related one https://bugzilla.redhat.com/show_bug.cgi?id=1544928

RHEL-7 status is new, the assigned analyst will define if it is affected and create the trackers, if needed
