Don't think this is OS related. I have a Win7 x64 Haswell system which needs 6 seconds to boot from Power Off to Desktop. My C2Q Working system needs about 45 seconds to boot from Power off to Win 8.1 x64 Start page... With Win7 x64 on the C2Q this time nearly is identical. Both systems have an identical SSD and the CPU are also on a comparable speed level... So this is a matter of the system itself much more than a matter of OS.booting is way faster in 8
What kind of configuration settings do you recommend to improve MP1 performance for Win7 / Win8?
