Why'd you minimize the pagefile? You're gonna get the best performance by just leaving pagefile as/is.
There are many opinions, but one fairly common one is that with lots of RAM, pagefile need be only enough to hold a minidump. Windows allows no less than 16 mb. Some recommend no pagefile for better performance of specific apps. That's why I tried it. Slight help. And no problems.
Perhaps I'm misreading this. Are you saying that the install for Windows 7 is larger than 32 gigs? In my experience it's usually around 10gb. Maybe 16 counting pagefile and hibernation file..
In bytes to avoid the 1024 vs. 1000 confusion.

application caches have generally been relocated to other drives or it would be larger.
numbers kept changing slightly during cut and paste so may not add exactly
edit: running windirstat "as administrator" shows that the "unknown" is in fact system volume information. However running windows explorer "as administrator" still lists svi size as zero.
