Hello, I'm posting for the first time ever....apologies in advance if this post is in the wrong place. So here is my problem. Running Parallels 12, 20GB virtual disk size. Wanted to upgrade to the new windows 10 anniversary update, decided to increase the Virtual disk size to 45GB. Successfully installed windows 10 update. Removed all installation files from windows (as they were taking extra space up). Trying to reduce the Virtual Disk size back to 20GB. However under parallel settings, the minimum size for the Virtual Disk shows up as 45GB. It does not allow me to shrink the size. I have double checked under windows 10, there is lots of free and un-used space. Any idea how can I can reduce the virtual disk size? Many thanks for your support.
