my laptop is 4 months old it came with windows 10 Opera keeps freezing and lagging it runs 8 processors and makes my disk max out 100% i use Internet Explorer and Firefox i don't like Chrome as it uses too may processors as well and i get the same problems as Opera as for Explorer and Firefox my only problems with them is Explorer won't stay in full screen and Firefox's plug-in container keeps crashing other then that i have no problems with Explorer or Firefox what would make me happy to keep Opera is the removal of the multiple processors as they use too much Disk space to run.
