Hi, Does anyone have any idea why all builds of W8 have run really slow on my machines? I don't think it's hardware specific, seeing as I've installed 2 of the builds on 2 different machines. Everything is laggy: moving windows, typing, web browsing, everything. I'm currently on 7989 on a fairly old PC, but it runs W7 perfectly well. Laggy as hell now. If anyone has any ideas, I'd love to hear them!
