So since the new Fall Update windows causes microlags when I open any application. If i open firefox for instance it would lag for 0.5 second then launch the app, same goes for anything else, apparently this is something lots of people experience. Anyone got an idea what is causing this mess? Windows is running on a Samsung Evo 840 SSD 250GB firmware is up to date. Maybe @Phoenix knows something since he seems to be working a lot on fixes and optimizations. SSD has been tested, is in good condition and didn't cause microlag when doing the test, so I'm 100% positive it's not the SSD.
