I rarely used 7.5 as I bought it a couple of weeks before 8 so I never checked.  It's uninstalled now.

I wonder if it's something to do with 64 bit because I tried with 6 but it didn't work even though it used to on my old 32 bit.  Also took a lot of effort to get the resources to drop below 70% which may be why it didn't work.   I need to try something that really eats resources to get it really low but was in a hurry.    If I'd put the same amoutn of stuff in 8 that Idid in that test though, it would have been well down.
