Where Windows 10 is concerned, rebuilding might not change anything. More than likely, you have an OEM version of Windows from a "Microsoft Partner", versus a retail build which could be considered (loosely) to be the baseline. In essence OEM's can (and do) alter Windows to suit their purposes which can significantly alter the build's security profile.
Well, the PC is custom built and windows is installed from the iso that i downloaded directly from microsoft, so it should be retail, right?
On your re-install's - doing several re-installs is not the same as getting it right. It's possible that you're doing something consistently wrong. (Don't take offense . "Stuff" happens, and this forum see's a lot of "stuff".)
Very much possible. I just hope that it keeps working now, otherwise ill just screenshot every single tab in the omv config and post it here
I might just be overseeing something simple that keeps breaking stuff.
BTW: Shut down your R-PI cleanly - meaning use shut down in the web GUI, wait 2 to 3 minutes, then reset power. Doing dirty shutdowns may, eventually, corrupt your install.
Yeah, thats something i messed up on the very first try. I didnt just cut power of course, but i used ssh and shutdown now, and i feel like that broke something.
From there onwards i always used the gui to shutdown.
