installubuntu.exe ?
Sorry, not much help, but I now have zero time for Windows 10 and Microsoft's perpetual 'test it in production' ideology.
Recent updates have caused hours of effort to resolve f##ked-up installs. Now that I've got Office 365 (through my work's HUP deal) I don't need Windows anymore, which is great.
I would have thought that your gfx card would have it's own memory - you haven't got integrated graphics consuming resources, have you ?
