Would it be possible to get rough guidelines as to what is “too big”? Also, any recommendations as to where I can find an iso for Server 2019 (or Server 2016) to install without desktop? The only kind I was able to find for free was the eval copies, which I understand HTB can’t use (correct me if that’s wrong).
You can find the ISO of Windows Server 2019 from the Microsoft official website. The ISO will allow you to choose which version of Windows you want to install (Desktop experience or not). Without the Desktop experience, the machine will be waaaaaay lighter.
