Windows 10 Technical Preview setup crashes every time on my machines directly after starting, before any user input is requested: " Your PC ran into a problem...". Just like Windows 8.1 setup - always same crash. "Microsoft Windows 8.1 Upgrade Advisor" says my machines are compatible! However, Windows 7 and 8.0 work without problems on these machines. Anyone has a solution? Is it so hard for M$ to get better skilled people?
