Lenovo 14W eMMC SSD is so slow... Trying to put Pagefile.sys to USB Flash drive fails...

Hello All,

I had currently bought a Lenovo 14W for my son but I am underwhelmed with the performance of this PC.  The CPU is always at 100%, the Disk access is always at 100% and if the RAM is 100% filled, the paging file runs extremely slow.

The system has 4gb eMMC drive and 4gb RAM embedded onboard.

I have purchased a Lexar USB3.1 Jumpdrive S47 64gb

Lexar USB Flash Drive 64GB

The USB thumb drive is extremely fast and is actually faster than the eMMC drive by 2.4 times.

In Windows 10, I tried to modify the Virtual Drives on the system properties to add the paging file onto the USB drive.  The USB drive does not show up at all.  I then try Readyboost to enable it on the drive but then I get the error: This device cannot be used for ReadyBoost.  ReadyBoost is not enabled on this computer because the system disk is fast enough that ReadyBoost is unlikely to provide additional benefit.

Now this is BS as I have tried another caching program called eBoostr and it is not really the same but it did increase the performance of Windows 10.  The system was peppier, performed faster and the CPU and Disk 0 was under 95% usage.

My goal is the following:

Find a way via the registry to allow USB Thumb drives to be allowed to be used for pagefile.sys
If the above fails, find a manual method to force enable ReadyBoost, Allow USB thumb drives to be enabled by force and see if it will provide a much needed performance boost.
Currently, the system must not reach its 3.8gb RAM limit otherwise the paging file becomes horrendous to the CPU, Disk and RAM performance.. 

Ideally, I would like to know if it is possible to "Build" my own Registry settings to enable the USB Thumb Drive Pagefile.sys 

Thanks in advance for all that can assist with this.
