I installed Windows 10 as an upgrade from Windows 7 on my father’s notebook and it went perfectly. Note, this is a machine that flat-out refused to run Windows 8.x because the notebook has one of those funky dual-GPU setups in which it has an ATi/AMD Radeon GPU and an Intel GPU (yes, I said it was a funky setup).
Under Windows 8.x the ATi/AMD and Intel GPU drivers never meshed right under Windows 8.x which resulted in video card support being well… completely FUBAR.
I said, what the hell… it’s a free upgrade, might as well try it. I did a Macrium Reflect disk image of the system disk just in case Windows 10 resulted in a FUBAR video situation. But, much to my surprise, Windows 10 supports this dual-GPU setup flawlessly.
WELL DONE MICROSOFT! God, I can’t believe I just said that. Let me go wash out my mouth, it tastes bad now.
