Can we presume this laptop was part of some program allowing students to buy a used device? I would think the school would want that device detached from it's network and would take care of that for you.
My laptop was bought from a school so it's under its domain, but because I've graduated, I wanted to get rid of that domain. What I did was I changed the settings and now I'm under a workgroup, and now I'm not able to do a lot of things because I no longer have administrative rights. I don't know why because this is the only account I can log onto, as in there aren't any other accounts on my computer (they don't even have that one where you can type in both the username and password), so my sole account should be the admin account but it's not.

My laptop is ancient (Fujitsu Lifebook T series, Windows Vista) and it drives me crazy already without all this nonsense but I just want to get rid of the domain first, but the problem now is that I can't even do administrative changes to the laptop so I'm stuck. I'm all for factory resetting but I don't even know how to factory reset this disappointing contraption. I'd also like to know what a domain does, like if a domain-controller can see the contents of computers under its domain and things like that.</div><span style="font-size: 14.4799995422363px;">
<span style="font-size: 14.4799995422363px;">I'm one step away from obliterating it with a sledgehammer but I don't own a sledgehammer so can someone help me?
