Hi Paul,
Thanks for the help! Unfortunately I wasn't able to run these Remove-WindowsFeature, Install-WindowsFeature commands because a windows 10 client-based operating system is installed on my workstation. Although I think these commands would accomplish the same
as the GUI for Turning Windows features on or off that I already tried.
Any other ideas, what I could try to get past this IIS Manager white screen problem? I was thinking, maybe it is using some sort of hardware acceleration and when I moved my SSD to my new PC, it run into some incompatibility with the new hardware.
Thanks in advance!
