Sysprep frozen

[Farinax]

Hi guys, i needed to use sysprep and when i needed to exit from it i clicked generalize and reboot
But now the problem: it rebooted and now it's stuck at "Applying system settings..." (translated from italian)
It's been like this for the past 2 hours, what should i do?

EDIT AFTER ANOTHER HOUR:
I tried doing Shift + F10 for the cmd so that i could see if the pc was doing something in the task manager
Well, cpu usage is at 0% and ram only 940mb off of 4GB
Now my question is, what will happen if i shut down the pc?

EDIT AFTER RESTART:
Now it just throws an error saying that it can't continue the installation of windows
How do i bypass this error? Already tried msoobe method but that is temporary, i wanted to image this system on an iso

Is this on an ssd or a mechanical HD? If you have a mechanical HD, this can happen due to bad/damaged sectors on the hard disk. You should run chkdsk /f on this installation of Windows from the Win RE environment.
