Looks like Windows doesn't exactly like patching resources within DLLs after all (but still does it):

Patching COMMAND.COM...
&DiskImage[filestart(=4200)+0x650c] = 0x000007fef0ee31e4
First-chance exception at 0x000000013f8df40b in rufus_fd.exe: 0xC0000005: Access violation writing location 0x000007fef0ee31e8.

If it ain't broke...

Unless we encounter a Windows platform where the files end up not being properly patched, leave it as it is.

Actually, the above, as well as the patching of the autorun.ico does crash the program when compiled as 64 bit with WDK.
Will have to duplicate memory to work around this issue.
