I have great news to share!
I have just updated my laptop to Windows 10, and I am happy to say that The Sims 2 Ultimate Collection will run perfectly fine on the Windows 10 software!
It was not officially stated if or if not The Sims 2 Ultimate Collection would work or not on Windows 10, but after launching it, it seemed to run fine!
My worries were that the game wouldn't run on Windows 10 because The Sims 2 is such an old game, but then there was a theory in my head that thought: "If The Sims 2 Ultimate Collection worked on Windows 8, then it should work on Windows 10!" and gladly my thought was right!
I am so happy to share this news with you and happy that our favorite old game is still running and performing strong!
