Hello community, I was running Parallels 14 with Windows 10 Pro 1909 and Mojave, I decided to do the full upgrade and upgraded to Catalina 10.15.6 and Windows 10 Pro 2004. I had to realize that Windows 10 became significantly slower so I checked the Task Manager for any disturbances. I then discovered that from my 4 GB RAM I assigned only 2GB were usable, so I shut down the machine and increased the amount to 6GB and checked again but had to realize that the usable RAM only increased by 700MB sinse the hardware reserved amount increased drastically to 3,3GB. I then did the same but this time I increased to 8GB (my System has 16GB build in). And then I started to wonder, the hardware reserved part increased to 5,3GB and the usable memory was still stuck to 2,7GB. What I already tried: 1) Upgrade to Parallels 16 2) Used msconfig to set the usable memory to full 8GB. 3) Checked the VM BIOS to see if the memory is displayed fully. What I also observed: 1) Also if I increase the usable CPU Core count it is not displayed in the task manager according. 2) Sometimes it seems to undo the changes made to the shutdown VM (memory reverted to 4GB). 3) The total amount of RAM my System uses is not displayed the slider bar in th VM config ony goes up to 8GB maximum. I can't find any solution, so any help is appriciated.
