I'm on ASUS N56VZ (all drivers checked and up to date)
after updating to 10074
I got this weird error when I try to "manipulate" any kind of file in the C: folder.
it seems i don't have the right to edit, copy, rename any file inside that partition,
I tried to solve this by editing the security privileges on Volume C properties but it changed nothing.
so I'm asking for support as soon as you can
Thanks for your help
