I confirm, you were correct about "Privacy" and "Settings" components ... they are saved correctly but not loaded correctly (with "LOAD" button) using a wccf ... I will fix it in the build which will be available tomorrow. Thank you very much for your report
About your Hyper-V virtual machine, the speed of a virtual machine depends essentially on the power of your microprocessor, the RAM memory size and your Hard Disk Drive (type and free space), this is also valid with other virtuallization software such as VMware Player or Virtualbox.
1 - with a powerful microprocessor (also known as "CPU") with 4, 6 or 8 cores : you are able to assign more microprocessor cores to speed the virtual machine ... for instance I think you have just one microprocessor core activated in your virtual machine. To be clear if you assign 2 cores instead of 1 core, you should double the power of your virtual machine
2 - with a lot of RAM memory (8Gb to 32Gb) : you are able to assign a lot of memory for your virtual machine, which speeds up by much your virtual machine
3 - with a fast hard disk drive (also known as "HDD") : if you have few free space on your hard disk drive, it will slow down, by much, your virtual machine. It exists other type of "HDD", known as "SSD" and they are very fast for this kind of usage
==> for example, I using a virtual machine, created with VMware Player, with 4 CPU cores, 4 Gb RAM and the virtual machine is entirely stored on an old intel SSD X-25V (40Gb) ... I install a winreduced windows 10 in less than 2 minutes
==> I think you must look at some HyperV tutorials to get the best speed ... but never forgot to choose wisely your virtual machine options to avoid instabilities in Windows 10 while using your virtual machine
@KrX : the "true" or "OK" values in the wccf are exactly the same, and this is a correct behavior ... but the recommended value is always "true".
