Hi! Parallels automatically allocates only 1 gig when creating a new Windows 10 machine. This is annoying, because the 10041 both requires 2g and is broken: if you fail the RAM check for 2g, it still marks itself as installed -> no way to make Windows retry the installation. Please make Parallels default to 2G of memory when creating Windows 10 machines. BR, LW
Hello Lauriw, You can increase the RAM manually, please Shutdown Virtual Machine > go to Virtual Machine Configure http://kb.parallels.com/117287 > Hardware > CPU & RAM > increase the RAM to 2 GB and start the virtual Machine and check if the issue still persisting.
