Temporary freezes and occasional "not responding" messages are not often seen in Windows 8, but occur much more frequently than they do in W7. Same hardware, same software. Only the drives and a few drivers differ. These hesitations arise in various programs or while manipulating UI options, and have since the earliest W8 betas, though they have become less frequent with each release. No forum messages that I have come across relate specifically to this random issue. Additionally, W8 is a multitasking slug as contrasted to W7 when, for example, a large file is downloading in the background. Open another program in W7 and it pops up almost immediately; open in W8 and it takes 15-30'. Priority has been assigned to both "programs" and "background services." Made no difference. 2600 Intel CPU, ASUS P8P67le MB, NVidia 210 GPU, at least 28G free space on each drive. Noted the same behavior or have suggestions on how to overcome it?
