This is what my Win 7 64 bit with 16GB RAM  is set to:

If you have 16 GB try changing yours to look like mine.

I have 12278mb, but the Maximum Memory box is unticked, do you want me to tick the box and enter 12278mb or leave it blank?

Are you talking about the msconfig or the Performance Options that I just posted?  Leave the MSconfig like it is but change the Performance Options to look like mine.  Make sure you check the Programs button.  You can make the Virtual Memory the same as mine.  The idea is to make it about the same size as your total  RAM but more doesn't hurt anything.  Just wastes some disk space.

I've just changed adjust perfromance to 'Programs'

But I need clarification where to put 16gb because I see two memory boxes here in my Advanced Performance Options.

NB: Still seeing "Error This upload failed" trying to upload attachments to G2G, so posting in box.com.

Changed Advanced Performance Options. Disabled Network Adaptor.
Didn't do speed test, but as soon as I launched ProcessExplorer, noticed atleast 100 Pagefaults that grew every second.
Here's a Latency Monitor log of that, without usbdeview open:

_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

 REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count:                 taskhost.exe

Safely Remove notifier didn't speed up and usb speedtests didn't improve, so I've changed Advanced Perfrmance Options back to what they were to benefit audio production.

Would rather you kept them where they were as your changes make no sense to me.  Did it really impact Audio?

I looked it up again on google, it seems that it's an outdated and possibly unnecessary tweak.

I will adjust it to how you advised.

I just think that if something is reliable and isn't causing a problem, I don't want to change it unless it improves something.

I am trying to get your system back to a standard config with no unknowns.  You may not think so but the last Latency Monitor log was the best we have seen so far. 

 

What does Latency Monitor look like now if you do not disable the network adapter when running a USB speed test?  What network adapter are you using?
