For now what you can very quickly do:Open go to \VirtualTest\ plugin UI on any other project (SE, Gena)Giving example with \VirtualTest\"VMware Emulation" plugin- right up "Select ISO" button, below change "Auto" to winvista or winvista-64- Click "Select ISO" and choose Win10XPE .iso file
A bit like it is done in PESE with the Standard file copy...Win10XPE uses the full Winre.wim with lightweight WinSxS and some language folders deleted.thus, It preserves all functionality including for example Refresh your PC...I gave up on the (lightened) Standard file copy in XPE. It is too much work to find the new files to include, delete old ones, and to check again and again all the features, each time Windows is updated, every 6 months.It is safer with the full light winre.wim and by trusting the work done by Microsoft.Also, $MS has progressed well since windows 7, they have the expertise, and the original boot.wim (or winre.wim) is getting better and better.
