Will adding more RAM speed things up, or is some limit reached with
extra RAM?



Are you running 32bit or 64bit Windows 10 ? 32 bit is only able to use
around 3.5 GB of ram.


Can Windows 10 use PAE?


Of course. It applies PAE to get NX (page table format quirk).
They need a place to store the NX bit, to protect data
segments from attempts to execute them (malware). The
NX stands for "no execution of this segment", that's the
basic idea. If the program counter wanders into such an
area, there's an access violation or something. Chunks of
memory are basically labeled according to their intended purpose
(data or instructions).

But the OS applies MS memory license of 4GB, so PAE cannot
be used for its intended purpose.

Even though PAE is perfectly willing to map stuff
above 4GB, the MS memory license cuts it off at the knees.

And that's where our 32-bit OS limitation comes from.

A dude here, hacks Vista 32-bit, to run all 8GB of
RAM on the guys machine. Just to show that PAE really
works on Vista+. And this is done by defeating the
memory license barrier.
