--- Comment #1 from François Gouget fgouget@codeweavers.com --- For some reason the Windows 8.1 cw-rx460 got a somewhat newer kernel32 library than the others:
w8 6.3.9600.17056 w864 6.3.9600.17056 cw-gtx560 6.3.9600.17415 cw-rx460 6.3.9600.19994
That's probably the reason for the difference in behavior. I confirmed that by upgrading w864 to the latest: it got kernel32 6.3.9600.20326 and started having the same failures.
Finally expanding the test confirms that the file copy does succeed.
